00:01:0100:01:05 Hello, and welcome to Doctor’s Talk.

00:01:0500:01:10 A podcast where doctors and health experts discuss various health-related topics.

00:01:0700:01:12 On the Zerosick channel.

00:01:1000:01:14 In this episode we have English subtitles.

00:01:1400:01:19 I’m Dr. Jimmy, a medical doctor specializing in preventive medicine.

00:01:1900:01:23 When talking about how to protect yourself from cancer, dementia

00:01:2100:01:25 or other serious diseases "exercise" is always a vital factor.

00:01:2300:01:28 I’ve repeated this in many episodes.

00:01:2500:01:31 That exercise is important for our bodies.

00:01:2800:01:34 But today, we will dive deeper into it's mechanism.

00:01:3100:01:37 And the misconceptions that everyone still believes.

00:01:3400:01:39 Surveys show that 90% of people who exercise in the gym don’t see any results.

00:01:3700:01:41 How should you exercise to see results?

00:01:3900:01:44 For those who want to build muscle, what should they do?

00:01:4400:01:48 And do supplements really help?

00:01:4600:01:51 Today, I’ve invited a famous trainer

00:01:4800:01:53 with a lot of experience to join us for a discussion.

00:01:5100:01:56 His name is KELVIN, hello!

00:01:5300:01:58 Hello, I’m PANUWAT RONGBANDIT – KELVIN.

00:01:5600:02:00 Currently a Professional Fitness Trainer.

00:02:0000:02:05 Certified by an international institution in America,

00:02:0300:02:07 called ACE or the American Council on Exercise.

00:02:0900:02:13 In addition, I’m also certified as a Strength Coach by NSCA.

00:02:1200:02:15 And I specialize in Group Exercise as well.

00:02:1300:02:17 Wow, you have so many certifications.

00:02:1700:02:22 Today, we’re going to share some knowledge about exercise.

00:02:1900:02:24 In today's life,

00:02:2200:02:26 when we wake up, we feel hungry so we need to eat, when we feel sleepy, we go to sleep.

00:02:2400:02:28 So why should we make time for exercise?

00:02:2800:02:32 How does exercise benefit our bodies?

00:02:3000:02:34 Looking at it from a structural standpoint

00:02:3200:02:36 exercise makes us feel more energetic.

00:02:3400:02:40 It helps us move our muscles and become stronger.

00:02:3600:02:42 It strengthens our bones.

00:02:4000:02:45 It helps us look younger.

00:02:4200:02:48 Like you!

00:02:4500:02:51 And it’s good for our mood, improving mental health as well.

00:02:4800:02:53 The cardiovascular and respiratory systems improve as well.

00:02:5100:02:54 Exercise comes in many forms.

00:02:5400:02:59 Is walking considered exercise?

00:02:5700:03:01 Or is it just a way of moving the body?

00:02:5900:03:03 How do we define what is exercise?

00:03:0100:03:05 Or just body movement?

00:03:0300:03:08 When it comes to exercise

00:03:0500:03:11 we categorize it as either exercise or non-exercise.

00:03:0800:03:13 I’d like to call it physical activity instead.

00:03:1100:03:18 Physical activity refers to how you live your daily life.

00:03:1300:03:20 What do you do, like walking or picking things up?

00:03:1800:03:23 The factor that tells us if you are exercising is

00:03:2000:03:25 whether you are challenging your body to do something harder.

00:03:2500:03:29 For example, walking should turn into walking faster, or maybe jogging.

00:03:2900:03:35 Or when you lift things, you should be lifting heavier weights than usual.

00:03:3500:03:39 And it should be a clear form that’s not too uncomfortable.

00:03:3700:03:42 Going shopping or something like that wouldn’t count as exercise.

00:03:4200:03:46 Exercise is defined by increasing your heart rate significantly.

00:03:4400:03:49 And using more strength, right? Yes.

00:03:4600:03:52 Today, there are many types of exercise that people enjoy doing.

00:03:4900:03:54 For example, running, weightlifting, yoga.

00:03:5200:03:56 So, how many types of exercise are there in total?

00:03:5400:03:58 In the past, exercise was classified into three types.

00:03:5600:03:59 But nowadays, there are four types.

00:03:5800:04:02 From what we see, new innovations are being introduced.

00:04:0400:04:08 Previously, it was categorized into a form related to the cardiovascular system.

00:04:0600:04:10 This is about how to make the heart stronger.

00:04:0800:04:12 Because the heart is like the engine of life.

00:04:1000:04:14 It’s important to see how it makes the heart contract and how blood circulates through the body.

00:04:1600:04:22 The second type is muscle and bone, which is about resistance training.

00:04:1900:04:24 And what people are increasingly looking for nowadays is flexibility.

00:04:2200:04:26 Mobility and flexibility.

00:04:2400:04:29 And another aspect that’s getting more attention is the nervous system, like balance.

00:04:3100:04:35 So, you’ve mentioned four types.

00:04:3500:04:39 The question is, how do I know which type of exercise suits me from these four types?

00:04:3700:04:42 Or do I need to do them all?

00:04:3900:04:44 Let’s look at it from a holistic health perspective first.

00:04:4200:04:47 All of these types should already be included in your routine.

00:04:4700:04:51 But there may be personal preferences that vary.

00:04:5100:04:56 For example, some people may prefer cardio activities, like running.

00:04:5400:04:58 It’s possible that they may focus more on this than usual.

00:04:5600:05:01 But of course, the other areas shouldn’t be neglected.

00:04:5800:05:04 Similarly, for people who enjoy weight training and resistance exercises,

00:05:0400:05:08 but have never done cardio, they should still include some cardio training.

00:05:0800:05:12 Because when you look at the overall picture, everything is interconnected.

00:05:1000:05:14 For example, if you’re doing weight training

00:05:1200:05:17 and you want to increase the intensity of the program

00:05:1400:05:19 but your cardiovascular system can’t handle it, and you get tired too quickly.

00:05:2200:05:25 Or, if you want to run longer but your muscles aren’t strong enough

00:05:2300:05:28 you haven’t built enough muscle.

00:05:2500:05:31 Similarly, if you want to train or increase your range of motion in running, to make your stride longer

00:05:3100:05:35 or to extend your step range

00:05:3200:05:38 if your mobility isn’t good

00:05:3500:05:40 it will affect your range, and your stride length may become shorter.

00:05:3800:05:42 And then there’s also balance.

00:05:4000:05:44 Some people might not understand what mobility is,

00:05:4400:05:48 Or what flexibility is,

00:05:4700:05:50 and how balance relates to exercise.

00:05:4800:05:52 Many people might understand running as "cardio"

00:05:5000:05:54 and weight training as "lifting weights"

00:05:5200:05:56 but how are mobility and flexibility related?

00:05:5800:06:01 Regarding mobility and flexibility

00:06:0000:06:04 if you observe your body right now

00:06:0700:06:14 you’ll notice that your body starts to decline in its function.

00:06:1100:06:17 For example, your arms should be able to raise above your head

00:06:1400:06:19 but if you sit at a desk all day, your arms start to get stuck.

00:06:1700:06:21 There’s a concept that says, "If you don’t use it, you’ll lose it."

00:06:1900:06:23 If you don’t use it, it will fade away.

00:06:2300:06:29 So, when one day you need to do an activity that requires that function

00:06:2500:06:31 you might compensate by borrowing movement from other parts of your body.

00:06:2900:06:33 In the end, it leads to improper movement.

00:06:3500:06:39 Which increases the risk of injury.

00:06:3700:06:41 Therefore, most people who exercise but have insufficient flexibility

00:06:4100:06:47 may be at higher risk of injury.

00:06:4500:06:49 And what about people who don’t exercise at all?

00:06:4900:06:56 Well, as you said, we’re born to eat, sleep, and walk.

00:06:5300:06:58 So, when we reach our reproductive age

00:06:5600:07:01 and become fully grown adults, the natural thing that happens to the body

00:06:5800:07:03 is the process of decline or deterioration.

00:07:0300:07:09 So, if you don’t exercise to maintain it

00:07:0600:07:11 or try to maintain it, it will decline.

00:07:1100:07:16 You can easily notice that people who don’t exercise much

00:07:1400:07:19 and don’t take care of themselves in terms of lifestyle,

00:07:1600:07:21 such as not being careful about what they eat

00:07:2100:07:26 or having unhealthy habits

00:07:2600:07:31 the first thing you’ll notice is that they seem to age faster than they should.

00:07:2900:07:35 Their bodies deteriorate more quickly.

00:07:3100:07:37 Or they might often feel unwell, get sick, or have frequent fevers.

00:07:3700:07:43 The purpose of exercise is mainly to help increase life expectancy

00:07:4300:07:48 and reduce the risk of various diseases.

00:07:4600:07:49 Whether it’s diabetes, obesity

00:07:4800:07:52 or heart-related diseases.

00:07:5200:07:56 Now, how does exercise affect our body or organs?

00:07:5400:07:58 If you engage in exercise

00:07:5600:08:01 such as cardio, involving the heart and lungs

00:08:0100:08:06 The first thing I’ll tell you is, as I mentioned, the heart is like the engine room of the body.

00:08:0600:08:12 If it isn’t stimulated, it will just keep working as usual.

00:08:0900:08:14 Every day, it just keeps beating away.

00:08:1200:08:15 The heart is also a muscle.

00:08:1400:08:17 It is a specific muscle, the heart muscle.

00:08:1500:08:19 It needs to be stimulated.

00:08:1700:08:22 So, to stimulate it, we need to make it work harder.

00:08:1900:08:24 Therefore, there must be an activity that makes it work harder.

00:08:2400:08:28 The benefit it gets from this is that the engine room becomes larger.

00:08:2600:08:31 The muscle becomes stronger.

00:08:3100:08:36 It helps make the blood pump once and supply the whole body.

00:08:3300:08:39 This is why, when people exercise

00:08:3900:08:43 you probably know, right, that the resting heart rate is lower.

00:08:4100:08:44 This means the heart doesn't need to work as hard.

00:08:4300:08:47 Compared to someone who doesn't exercise

00:08:4400:08:49 just walking up one or two floors can make them tired.

00:08:4900:08:54 This is one of the benefits of heart training.

00:08:5400:08:59 Nowadays, people are into weightlifting to build muscle.

00:08:5900:09:04 I want to ask, is building a lot of muscle good for our body?

00:09:0400:09:08 I feel it's really great that people are starting to be interested in weight training.

00:09:0600:09:10 Because in the past, it might have been only for certain groups of people.

00:09:1000:09:15 But I must say, the benefits go beyond just strength

00:09:1200:09:16 and muscle mass.

00:09:1600:09:21 You already know, right, that muscle mass is like a "cell sheet," Yes, that's right.

00:09:2100:09:26 Actually, having more muscle mass can help increase lifespan.

00:09:2400:09:28 It helps you look younger.

00:09:2600:09:30 And of course, it helps with being more agile.

00:09:2800:09:32 And with more bone mass.

00:09:3000:09:36 This means you will have long-lasting strength.

00:09:3200:09:39 It slows down the degeneration and decline of the body.

00:09:3600:09:42 Strength will last longer, things like that.

00:09:4200:09:49 At the end of each year, many people often set the intention that next year they want to be healthier.

00:09:4600:09:52 They’ll go to the gym, pay for the gym membership, pay for a trainer.

00:09:4900:09:55 After a month, they lose motivation.

00:09:5500:09:59 Do you have any advice on how to build self-discipline or find inspiration?

00:09:5700:10:02 To be able to exercise for health?

00:09:5900:10:04 I think you need to set a goal first.

00:10:0200:10:06 Yes, everything needs to have a goal.

00:10:0600:10:11 Because if you don’t have a goal, you won’t have anything to aim for.

00:10:1100:10:16 When you do anything, I recommend you should keep track of it.

00:10:1600:10:22 A simple way, just as a basis, you might weigh yourself every morning.

00:10:1900:10:25 Or weigh yourself once a week, that’s enough.

00:10:2700:10:32 And you need to observe how things change once you control your diet and exercise.

00:10:3000:10:34 Because if you keep track, you’ll have numbers.

00:10:3200:10:36 The numbers don’t lie; they are clear.

00:10:3400:10:39 There’s something tangible to hold on to.

00:10:3600:10:42 But most people think and do, but don’t track.

00:10:4400:10:48 So, there’s no way to see progress or how they’ve improved.

00:10:4800:10:52 Personally, I’ve encountered this too.

00:10:5000:10:55 When patients come to my clinic, some come because they want to lose weight or have obesity.

00:10:5500:11:00 The first thing I do is ask them to take pictures of their meals for me to see.

00:10:5800:11:02 To see what they eat at home every day.

00:11:0200:11:07 Secondly, I have them make a chart, where everyday they wake up at the same time.

00:11:0500:11:11 Let’s say at 8 AM every day, then have them weigh themselves at home.

00:11:0700:11:13 And have them record it.

00:11:1100:11:16 Then after 2-3 months, we can see what changes have happened.

00:11:1600:11:21 Doing this allows patients to see from the photos they took.

00:11:1900:11:23 Whether the food they ate was as bad as they thought, or maybe it was actually good.

00:11:2300:11:27 Then they’ll realize there have been changes in their body weight.

00:11:2500:11:29 Because losing weight takes time.

00:11:2700:11:32 Many people think they can lose 5 kilograms in just one week.

00:11:2900:11:35 That’s just not possible.

00:11:3200:11:38 Now, for people who are really lazy to exercise,

00:11:3500:11:41 if they exercise the bare minimum, what would you recommend?

00:11:3800:11:43 There’s a guideline from ACSM.

00:11:4300:11:48 It says that at least, for good health

00:11:4600:11:51 To reduce the risk of various diseases,

00:11:5100:11:56 you should exercise for at least 150 minutes related to cardiovascular health.

00:11:5600:12:00 And also do resistance training at least 2 times a week.

00:11:5900:12:03 So to sum it up, you should exercise at least 150 minutes per week.

00:12:0000:12:05 And do resistance training 2 times per week.

00:12:0300:12:07 But for the 150 minutes, does it matter what your heart rate should be?

00:12:0500:12:09 Or, like people say, it should be in Zone 1, Zone 2, or Zone 3?

00:12:0700:12:11 Does that matter?

00:12:0900:12:13 Yes, it does matter.

00:12:1100:12:16 It specifies that the intensity should be at a moderate level.

00:12:1300:12:18 Which means moderate intensity.

00:12:1600:12:21 So, when you measure it, for people who have an understanding,

00:12:1800:12:23 or for runners, they might calculate it.

00:12:2100:12:26 But for people who might not fully understand,

00:12:2300:12:29 a simple method is to observe your ability to speak.

00:12:2900:12:34 While exercising, you should feel like you can talk, but it’s difficult.

00:12:3400:12:39 Once you start exercising and try to talk to someone, it should be hard to speak.

00:12:3700:12:42 You should start feeling tired and out of breath. That’s when it’s moderate intensity.

00:12:3900:12:43 Yes, yes. It’s like if you were walking on a treadmill next to me.

00:12:4300:12:49 And you could talk to me the whole time, that means the intensity isn’t high enough yet.

00:12:4600:12:52 But if you start jogging and speaking, and then feel out of breath

00:12:4900:12:54 That means you’ve reached moderate intensity.

00:12:5600:13:00 This is a simple way to monitor using your ability to speak.

00:13:0000:13:05 But in reality, there are more precise ways to measure, though they’re a bit more complicated.

00:13:0300:13:08 Yes, I think it’s fine to start with the simple method first.

00:13:1100:13:15 Many people ask how often they should go to the gym to see results, especially for weight training.

00:13:1300:13:17 How many times per week should they go to the gym to get the best results?

00:13:1500:13:19 And how many sets should they lift?

00:13:1700:13:21 Let’s talk about the minimum first, for health.

00:13:2100:13:26 As I mentioned, at least 2 times per week.

00:13:2600:13:33 Now, about the duration, it depends on your availability.

00:13:2900:13:35 Because not everyone has the same amount of free time.

00:13:3300:13:38 But of course, what’s important is what your goal is.

00:13:3500:13:41 If your goal is to build muscle

00:13:3800:13:44 going to the gym just 1 or 2 days a week

00:13:4100:13:47 might not be enough, and you may need to increase the volume.

00:13:4400:13:49 You asked if it’s possible to train in just 1 or 2 days?

00:13:4700:13:52 Yes, it’s possible, but the volume would have to be very high.

00:13:4900:13:54 Because it’s full-body training.

00:13:5400:13:59 It might take 2-3 hours in the gym.

00:13:5600:14:01 But realistically, most people can’t do that.

00:14:0100:14:06 So, when it comes to duration, it really depends on your goal.

00:14:0600:14:10 If you want to lose weight,

00:14:0900:14:12 you’ll need to burn calories.

00:14:1000:14:14 Or increase your physical activity.

00:14:1200:14:16 If you want to build muscle

00:14:1400:14:19 You need to lift weights to stimulate your muscles more frequently.

00:14:1600:14:20 So, the volume will increase based on your goal.

00:14:2000:14:25 If we talk about people who want to build muscle,

00:14:2200:14:28 if you were to give advice, how many times a week should they lift weights?

00:14:2800:14:33 I think it should be at least 3 times a week.

00:14:3300:14:39 And you should probably use a weight that we call moderate weight.

00:14:3600:14:43 To explain simply, you should lift until you’re exhausted.

00:14:3900:14:45 In about 8-12 repetitions.

00:14:4300:14:48 As for the number of sets, it should be at least 3 sets.

00:14:5000:14:55 When lifting weights, do you need to set how many sets to do in one session?

00:14:5300:14:58 The minimum should be at least, for beginners

00:14:5800:15:03 2-3 sets to get used to it.

00:15:0000:15:06 But if you’re talking about building muscle

00:15:0300:15:09 3 is the minimum. Therefore, you may need to increase it to 4 sets.

00:15:0600:15:12 Or 5 sets per exercise.

00:15:0900:15:14 This means there may need to be several exercises, like 4-5 different movements.

00:15:1400:15:18 These will be the total volume that the muscles are getting weight from.

00:15:1800:15:22 So if you want to build muscle, this is one of the variables.

00:15:2200:15:27 It’s called the load volume, or the weight that the muscle group is getting.

00:15:2400:15:29 Can we split the days? For example, on Monday, I want to work on my chest, just chest.

00:15:2700:15:32 On Tuesday, I want to work on my arms, just arms.

00:15:2900:15:36 Split it into 7 days, with each day dedicated to a different body part.

00:15:3600:15:41 Or should we work on 2-3 muscle groups in one day? Which one is better?

00:15:3900:15:43 Actually, both methods are possible, but it depends on experience.

00:15:4300:15:46 If you’re an athlete

00:15:4500:15:49 or someone with experience,

00:15:4600:15:51 they may train all 7 days.

00:15:4900:15:54 And on each day, they might focus on just one muscle group.

00:15:5100:15:56 For example, chest, shoulders, back, arms on one day.

00:15:5400:15:58 But if you observe, they’re in the gym for 3-4 hours.

00:15:5800:16:04 The principle is the same. They focus on the load volume.

00:16:0100:16:07 But for the general public, for health purposes

00:16:0700:16:11 I’d say we don’t have that much time.

00:16:0800:16:13 How much time do you spend in the gym?

00:16:1300:16:17 One hour, and that’s it.

00:16:1500:16:19 So, the principle is that we need to stimulate it more frequently.

00:16:1900:16:25 Generally, it’s recommended that each muscle group should be stimulated at least twice a week.

00:16:2200:16:28 For example, if you train chest, back, and arms on Monday

00:16:2500:16:31 you might need to train again on Thursday.

00:16:2800:16:33 You need to stimulate the muscle group at least twice a week.

00:16:3100:16:36 This applies if you have limited time.

00:16:3800:16:43 Unless, of course, you say that you’ll focus on Monday only.

00:16:4000:16:45 And if you’re in the gym for 2 hours and push hard

00:16:4300:16:47 as long as the volume of load is sufficient, then it’s okay.

00:16:4700:16:53 Let’s talk about an issue that many people still believe in.

00:16:4900:16:55 That is, if you want to loose weight, you need to do a lot of cardio, no need for weight training or yoga.

00:16:5300:16:57 Only cardio, that’s the only way.

00:16:5700:17:03 To sweat a lot and burn a lot of calories. Is that true?

00:17:0000:17:05 It depends on what kind of weight loss you want.

00:17:0300:17:07 And also, losing weight isn’t the same for everyone.

00:17:0500:17:10 In the case I’m saying "Yes" is

00:17:0700:17:13 if you only do cardio

00:17:1000:17:15 everything is about burning calories.

00:17:1300:17:18 If you only do cardio,

00:17:1500:17:20 what will happen is you’ll lose weight.

00:17:1800:17:22 For those who only do cardio,

00:17:2200:17:28 have you noticed why your body doesn’t look toned?

00:17:2800:17:31 It’s possible that what you’re doing is burning calories.

00:17:3100:17:36 But at the same time, you may be losing muscle mass.

00:17:3300:17:38 So what should you do?

00:17:3600:17:41 Besides cardio, you should also do resistance training.

00:17:3800:17:43 And focus on controlling your diet.

00:17:4100:17:46 Some people exercise a lot, but their weight doesn’t go down. Why?

00:17:4300:17:48 Because they eat a lot, they just eat too much.

00:17:4600:17:51 Exercising a lot but eating a lot as well.

00:17:5100:17:56 This is another reason why some people fail to lose weight.

00:17:5300:17:59 Or for some people, even after losing weight, they don’t have muscle, and their body looks flabby.

00:17:56.12000:17:01.320 The body looks loose, which affects the body shape.

00:18:0100:18:05 Now, when it comes to exercise, should we focus more on cardio,

00:18:0300:18:07 more on weight training, or should it be balanced?

00:18:0500:18:10 For those who want to lose weight, what do you recommend?

00:18:1000:18:15 For those who want to lose weight, we need to go back to discussing the approach.

00:18:1500:18:21 First of all, when it comes to cardiovascular exercise

00:18:1700:18:24 or cardio, it should be done more frequently.

00:18:2100:18:27 It may need to exceed the previously mentioned 150 minutes.

00:18:2700:18:32 It might need to be 250 minutes or even 300 minutes per week.

00:18:3000:18:36 This means you should set a target first.

00:18:3200:18:39 For example, once you have that number, say 250

00:18:3600:18:42 divide it by the days of the week to see how much you should aim for each day.

00:18:3900:18:44 And don't forget, you can do it gradually.

00:18:4200:18:48 For example, if you divide it for one day, you may need to do 40 minutes.

00:18:4400:18:50 You might do 20 minutes in the morning and 20 minutes in the evening.

00:18:4800:18:53 Or you can split it into 3 sessions a day.

00:18:5000:18:56 For example, 10 minutes in the morning, 10 minutes at noon, and 20 minutes in the evening.

00:18:5300:18:59 This can also be helpful.

00:18:5600:19:02 Including strength training, this is important.

00:19:0200:19:08 I think most people don’t overlook it, but they just don’t understand it.

00:19:0600:19:10 Because when you compare, cardio is easier.

00:19:0800:19:14 You just put on your shoes and go for a run or do something simple.

00:19:1000:19:17 But when it comes to weight lifting, people don’t understand what strength training is.

00:19:1700:19:23 Actually, it could be basic weight lifting exercises

00:19:2000:19:25 such as squats or push-ups, something like that.

00:19:2300:19:28 Initially, 2-3 times a week

00:19:2500:19:30 to stimulate muscle maintenance.

00:19:2800:19:32 Or to increase muscle mass if you add more load.

00:19:3500:19:40 Earlier, you mentioned that exercise should be at least 150 minutes per week.

00:19:4000:19:45 Now, some people still don't lose weight even after doing 150 minutes of cardio per week.

00:19:4500:19:50 How should you explain to them to help them understand better?

00:19:4800:19:52 That 150 minutes of cardio might not be enough for them.

00:19:5000:19:54 When it comes to the principle of weight loss,

00:19:5400:20:01 in the end, it comes back to the concept of "Calories in - Calories out."

00:19:5800:20:03 If you consume more than you burn, your weight won’t drop.

00:20:0100:20:05 If you want to lose weight, you need to burn more than you consume.

00:20:0500:20:10 Let’s say some people say, "I’ve done 150 minutes of exercise already."

00:20:0800:20:13 That's fine, keep that up and continue doing it.

00:20:1000:20:16 Now, we may need to look at other factors you might be overlooking.

00:20:1300:20:20 Because most people focus only on the time spent working out.

00:20:1600:20:24 They focus on the time spent lifting weights or doing cardio.

00:20:2000:20:26 But they forget about other factors surrounding it.

00:20:2400:20:31 For example, sleep and nutrition.

00:20:2600:20:35 And another point, from my perspective

00:20:3500:20:39 I think Thai people tend to underestimate the calories in their meals. They think this portion isn’t too much.

00:20:3700:20:41 They think the calories are fine, but in reality, it's actually a lot more than they think.

00:20:3900:20:43 It’s much more than you think, something like that.

00:20:4100:20:47 So you might need to reconsider that factor.

00:20:4700:20:52 And you’ll need to allocate more time as well.

00:20:4900:20:54 Or another option, if you say that 150 minutes is not enough

00:20:5200:20:57 Actually, there's another key factor, but you’ll have to trade off.

00:20:5400:20:59 As I mentioned earlier, 150 minutes or 250 minutes of moderate intensity.

00:20:5700:21:01 If you say you don’t have enough time, that means you need to make it more intense but shorten the duration.

00:21:0100:21:07 This is what we call high-intensity exercise.

00:21:0700:21:10 It's called high-intensity level.

00:21:0800:21:14 So, what exactly is high-intensity exercise?

00:21:1000:21:16 As I mentioned earlier, during exercise, you should still be able to talk.

00:21:1400:21:18 But for this level, you should not be able to talk anymore. It's difficult.

00:21:1600:21:21 But it depends on the time that is convenient for you.

00:21:1800:21:23 It can be modified, or it’s good to mix both.

00:21:2300:21:28 Let me ask more questions, how many minutes should it be if you want to make it so intense that you can’t speak?

00:21:2400:21:31 If we’re talking about the shortest, it's 75 minutes per week.

00:21:2800:21:33 That's the minimum.

00:21:3100:21:38 The minimum is 75 minutes - 150 minutes for high-intensity exercise.

00:21:3800:21:43 But if it’s moderate intensity, it’s 150 minutes or more.

00:21:4000:21:46 For weight loss, it should be 250 minutes or more.

00:21:4300:21:49 You can even do 300 minutes. The more you do, the better the result.

00:21:4600:21:51 Don’t forget to control your calorie intake as well.

00:21:5100:21:55 Now, earlier we talked about doing cardio.

00:21:5500:22:01 Most people think about running or using a treadmill.

00:21:5800:22:04 You run on the treadmill for 40 minutes, and the machine says you've burned 500 calories.

00:22:0100:22:06 But actually, it’s not quite right. The treadmill might be inaccurate. What do you think about this?

00:22:0400:22:09 I have to say, everything in this world has room for error.

00:22:0900:22:14 So, how do you know if the calories burned displayed by the treadmill are accurate?

00:22:1400:22:18 Sometimes, people might forget to input their information.

00:22:1800:22:23 For example, when using a treadmill, what details do you need to enter?

00:22:2100:22:25 You enter your age, weight. Some people might be hesitant to input their real weight.

00:22:2300:22:27 That’s the reason why the readings can be inaccurate.

00:22:2700:22:33 You need to check for any variables that might cause discrepancies.

00:22:3300:22:37 First and foremost, the systems on these machines.

00:22:3700:22:42 Each system has its own setup, but we can never be sure how each brand

00:22:4000:22:44 or model is designed. Sometimes, they may not be the same.

00:22:4200:22:46 Or they might use different calculation methods.

00:22:4600:22:51 Therefore, if you frequently use a specific machine

00:22:4900:22:53 you might rely on the numbers from that machine.

00:22:5100:22:55 But if one day you have to travel or go abroad

00:22:5300:22:57 you’ll need to check whether this new machine is different.

00:22:5700:23:02 At least you’ll have a guideline

00:23:0000:23:04 or a reference to understand that this machine says it burns this many calories.

00:23:0400:23:11 But it’s important to understand that there’s room for error.

00:23:0800:23:13 It could vary by 50-100 calories.

00:23:1100:23:16 This is due to data variables in the machine.

00:23:1600:23:21 So, for people who are exercising,

00:23:1800:23:24 how do you count calories? Can you use a smartwatch instead?

00:23:2100:23:26 I have to say, achieving maximum accuracy in measuring calories is quite difficult.

00:23:2400:23:29 Unless you go to a lab.

00:23:2600:23:31 You’d need to get tested in a proper lab.

00:23:3100:23:37 Or nowadays, there’s something called VO2 Max testing.

00:23:3500:23:40 What is VO2 Max?

00:23:4000:23:44 It measures how much oxygen your body can use when you breathe in.

00:23:4200:23:47 What percentage of your total 100% can your body use?

00:23:4400:23:49 It also calculates your training zones.

00:23:4900:23:53 And it can give you a clear idea of what you need to train for.

00:23:5100:23:55 But most of these tests are done in hospitals.

00:23:5500:23:59 So, they’re quite complicated.

00:23:5700:24:02 Keep in mind your goals too.

00:23:5900:24:03 For example, if you’re exercising for health

00:24:0200:24:05 this might go beyond what you need to do.

00:24:0500:24:10 So, when you choose a device, you might want to consider it carefully.

00:24:0700:24:14 I think it does matter, each brand.

00:24:1400:24:19 You should check what kind of values it provides.

00:24:1700:24:23 How can you tell which device is more accurate?

00:24:1900:24:25 They say you should choose one that’s closer to the heart for better accuracy.

00:24:2500:24:30 In the past, it used to be a chest strap.

00:24:3000:24:36 These technologies actually came from the military.

00:24:3300:24:38 When military units went into battle, they would check their vitals.

00:24:3600:24:40 It was developed from there and later adapted for sports use.

00:24:3800:24:43 Then it was further developed for health purposes.

00:24:4000:24:45 In the past, there was a strap.

00:24:4300:24:47 But for those exercising, it was uncomfortable.

00:24:5000:24:54 So, innovations were made to make the device smaller and smaller.

00:24:5200:24:57 Now, they can be worn on the wrist or here, for example.

00:24:5700:25:02 But if you observe closely, it tracks along the blood vessels to monitor heart rate.

00:25:0200:25:07 In summary, if you’re comfortable buying these kinds of devices, you can choose one that suits you.

00:25:0400:25:09 Just pick the one that works best for you.

00:25:0700:25:11 But don’t forget that these devices

00:25:0900:25:13 whether it’s a treadmill or a watch, might have some inaccuracies.

00:25:1100:25:15 So, don’t fixate on the exact number, like thinking you burned exactly this much.

00:25:1300:25:18 Then go ahead and eat whatever you want, thinking it's all balanced.

00:25:1500:25:21 My personal tip is to give yourself a 100-200 calorie buffer.

00:25:2100:25:28 For example, if the device says you burned 600 calories

00:25:2400:25:32 I’d suggest you estimate a lower value, like 400-450 calories, for example.

00:25:2800:25:35 It’s tiring just thinking about it.

00:25:3200:25:37 Thinking like this might help.

00:25:3500:25:40 Earlier, you mentioned exercising

00:25:3700:25:42 especially about building muscle in the body.

00:25:4200:25:46 Now, I want to understand the mechanism of muscle building in our body.

00:25:4600:25:51 How does it start? Like when we lift weights or do weight training.

00:25:4800:25:53 And why does our muscle hurt after exercising?

00:25:5300:25:58 Some people might think that muscle building starts when lifting weights.

00:25:5800:26:04 Actually, the mechanism is that muscle building happens when you rest.

00:26:0400:26:11 The problem is that most people don’t allow themselves to rest.

00:26:1100:26:16 They keep repeating and repeating.

00:26:1400:26:18 Something like that.

00:26:1600:26:21 Sometimes, you might be overstimulating it.

00:26:2100:26:25 The actual principle behind muscle building is that

00:26:2200:26:29 it requires something called overload, which refers to the weight.

00:26:2900:26:34 The weight we use in lifting.

00:26:3100:26:37 That creates stimulation at the cellular level to

00:26:3400:26:38 trigger an inflammation process that helps build muscle.

00:26:3700:26:41 To make this happen, apart from the load

00:26:4100:26:45 there’s also the volume of weight that the muscle group gets.

00:26:4200:26:48 This is called volume.

00:26:4500:26:51 Next, something essential is

00:26:4800:26:55 protein intake, or eating protein.

00:26:5100:26:57 Are you consuming enough protein daily?

00:26:5500:27:00 This helps in recovery, repair, and muscle growth.

00:26:5700:27:03 And of course, rest.

00:27:0500:27:10 To put it simply, lifting weights is like you’re smashing a wall

00:27:0800:27:13 making it crack.

00:27:1300:27:19 Then, a process happens at the cellular level.

00:27:1500:27:22 What happens is that it's like having workers coming in to plaster the walls.

00:27:1900:27:24 What is this plaster? It’s the food we eat.

00:27:2200:27:26 The intake that goes in.

00:27:2400:27:29 They keep applying it, over and over.

00:27:2900:27:33 This is the basic mechanism, made simple to understand.

00:27:3100:27:36 The muscles tear and repair in a way that builds them.

00:27:3600:27:43 Then, there’s the process of synthesizing new protein fibers.

00:27:4300:27:48 Now, the question is whether the stimulation stays the same or increases.

00:27:4800:27:52 It depends on the amount of protein intake and also on your recovery.

00:27:5200:27:56 Earlier, you mentioned overload or intensity.

00:27:5400:27:59 I’d like to know more about how intense the overload should be.

00:28:0400:28:11 According to research, it is suggested that the weight you lift should be in the range of

00:28:0800:28:13 67-80% on average of your maximum lift.

00:28:1100:28:17 This means that

00:28:1300:28:19 the weight you lift should be challenging enough to exhaust you within about 8-12 repetitions.

00:28:1700:28:21 Some data might suggest 6-12 repetitions instead.

00:28:2100:28:27 Another factor is the rest period between sets.

00:28:2400:28:30 There are many variables in training for each set.

00:28:3000:28:37 For example, when you lift, are you lifting quickly or slowly? Is it too fast or too slow?

00:28:3400:28:39 Do you have enough sets and repetitions?

00:28:3700:28:42 Including the rest time between sets, all of these variables are related to each other.

00:28:4200:28:47 Can you please suggest how long to rest after finishing a weightlifting session?

00:28:4400:28:49 How many hours should you rest the muscle before training it again?

00:28:4900:28:54 It depends on the individual, but according to general guidelines

00:28:5400:28:59 or research studies, it is recommended to rest for 48-72 hours.

00:28:5700:29:02 So how is it measured? It’s measured by who recovers faster.

00:28:5900:29:04 Some people may be able to train again sooner than that.

00:29:0400:29:09 You can observe this by the soreness you feel.

00:29:0700:29:12 When it comes to feedback, you need to look at whether the muscle soreness you feel

00:29:1200:29:17 or the inability to lift means you’re not ready to train that muscle again.

00:29:1700:29:22 If you go back to training too soon, instead of healing, it’ll just hurt more.

00:29:2200:29:28 Many people, when they lift weights for the first time, experience muscle soreness.

00:29:2800:29:34 So how does this kind of soreness happen after weightlifting or exercise?

00:29:3400:29:38 Muscle soreness, from a physiological perspective

00:29:3600:29:41 or in terms of internal body function—what happens during weight training

00:29:3800:29:43 is that the body needs oxygen.

00:29:4100:29:46 The muscles need to draw in oxygen to function.

00:29:4600:29:52 What happens is that the muscles may experience oxygen deficiency.

00:29:4800:29:54 As a result, the body produces lactic acid.

00:29:5400:30:00 But the key factor—the outcome—is that

00:29:5700:30:03 this lactate builds up and accumulates.

00:30:0000:30:05 That’s what causes the soreness, known as DOMS.

00:30:0300:30:08 Delayed Onset Muscle Soreness.

00:30:0500:30:10 When I first started training, I didn’t know this either.

00:30:0800:30:12 This is something you need to be careful about.

00:30:1200:30:16 Sometimes, your friend might have been training for a year or two already,

00:30:1400:30:20 but you’re just starting weight training on your first day.

00:30:1600:30:23 Your friend probably doesn’t realize that and encourages you to go all out.

00:30:2000:30:25 Sure, you might be able to lift at that moment, but after two days

00:30:2300:30:28 your experience using the toilet will never be the same.

00:30:2500:30:31 Even putting on a shirt will feel different.

00:30:2800:30:34 That’s why people who are just starting out should ease into it.

00:30:3100:30:37 Start lifting gradually—don’t jump into intense training right away.

00:30:3400:30:40 Because it could lead to injuries.

00:30:4000:30:44 Or cause an excessive increase in protein synthesis or other such effects.

00:30:4400:30:50 Which can result in soreness.

00:30:4600:30:52 For those who want to build muscle, what are some common misunderstandings?

00:30:5000:30:56 Could you share from your experience?

00:30:5200:30:59 One of the most common things I see is people focusing on the same muscle group over and over again.

00:30:5600:31:03 They keep training it repeatedly.

00:31:0300:31:09 Another thing I’ve noticed is people lifting too quickly without controlling the tempo.

00:31:0900:31:14 So, does lifting quickly versus lifting with controlled tempo really make that much of a difference?

00:31:1200:31:16 Does it really produce significantly different results?

00:31:1600:31:22 If the goal is to cause microtears in the muscle at the cellular level

00:31:1900:31:23 then the key variable is resistance.

00:31:2200:31:26 When it comes to muscle contractions

00:31:2300:31:29 —it’s important to understand that there are three types.

00:31:2600:31:33 There’s isometric (holding a contraction), concentric (muscle shortening), and eccentric (muscle lengthening).

00:31:3300:31:36 If you want DOMS (delayed onset muscle soreness) to be effective

00:31:3600:31:42 it usually comes from resisting a force.

00:31:4000:31:44 That means when you slow down the movement.

00:31:4200:31:46 For example, when doing a bench press PR,

00:31:4600:31:50 most people just push the weight up quickly.

00:31:4800:31:53 And when speed becomes part of the movement

00:31:5000:31:56 —you’re actually using less muscle force.

00:31:5300:31:58 Instead, momentum takes over.

00:31:5800:32:03 So your muscles are doing less of the actual work.

00:32:0300:32:10 Actually, I have a technique to share.

00:32:0800:32:13 First, try to slow down during the lowering phase and make the lifting phase smooth—focus on tempo.

00:32:1000:32:15 This is called Eccentric Load.

00:32:1500:32:21 This can help increase muscle microtears by about 20–30% at the cellular level.

00:32:2100:32:26 Next is applying pressure or stress on the muscle.

00:32:2600:32:34 After lifting, you should rest appropriately.

00:32:3000:32:36 But some people lift for one set, then play on their phones and rest for 10 minutes.

00:32:3400:32:39 That’s what I call “sweet and slow weight training” (a metaphor for overly relaxed training).

00:32:3900:32:43 Actually, you should track your rest time.

00:32:4100:32:45 So how many minutes of rest is appropriate?

00:32:4500:32:51 For muscle building, there’s a rest window—around 30 seconds to no more than 120 seconds.

00:32:5100:32:57 If you want to be strict about it, you should time your rest periods.

00:32:5400:32:58 Or allow a slight margin—give or take a little.

00:32:5800:33:04 It’s about allowing energy systems to recover under pressure.

00:33:0400:33:10 It’s about applying the right amount of stress to the muscle.

00:33:0600:33:11 Because if you rest too long, the muscle just relaxes and doesn’t get stimulated.

00:33:1100:33:17 What are the 3 key steps to definitely build muscle?

00:33:1400:33:19 Mainly, it’s about the program.

00:33:1900:33:25 You need to have a clear training program and use weights that match your goal.

00:33:2500:33:33 That includes lifting with proper tempo—slowing down the eccentric (resisting) phase.

00:33:2900:33:36 Next is making sure your rest time is appropriate.

00:33:3300:33:38 And third is the total load volume.

00:33:3800:33:42 Keep track of how much total weight you’ve lifted for a specific muscle group.

00:33:4200:33:48 This is called Load Volume —the higher it is, the more it stimulates muscle development.

00:33:4800:33:53 Another key point is eating enough —especially protein.

00:33:5300:33:58 Some guys want six-pack abs and ask, “Can I just train abs only?”

00:33:5500:34:01 “Can I skip everything else so the abs pop out clearly?”

00:34:0100:34:07 Well, it’s one possible approach.

00:34:0400:34:10 But it’s not really ideal, not good in the long run.

00:34:0700:34:12 When you train a specific muscle group

00:34:1000:34:14 you have to understand that abs are already being used

00:34:1200:34:16 during compound exercises.

00:34:1600:34:21 But if you want them more defined, you can focus on them,just don’t train them alone.

00:34:2100:34:26 There needs to be balance across muscle groups.

00:34:2300:34:28 You might’ve seen people who only train their abs,

00:34:2600:34:30 or just the chest, what we call mirror muscles.

00:34:2800:34:34 They look great in the mirror,

00:34:3000:34:36 but when you look at their posture and structure, their shoulders are hunched,

00:34:3400:34:38 and their body slouches like that.

00:34:3800:34:41 So it’s better to train with a balanced program.

00:34:4100:34:45 Earlier you mentioned compound movements. What are those?

00:34:4500:34:51 They’re exercises that involve large muscle groups and multiple joints.

00:34:4800:34:54 A basic example would be a bench press

00:34:5100:34:57 barbell rows, or using pulling machines, things like that.

00:34:5700:35:01 Or leg exercises like squats, deadlifts, or shoulder presses

00:34:5900:35:04 all those are compound movements, right? Right.

00:35:0100:35:06 Because they use multiple muscles and joints.

00:35:0600:35:11 They also engage your core to support your back.

00:35:0800:35:14 So your abs are already working to a degree during those.

00:35:1100:35:16 Then you can go in and add isolated ab training to really define them.

00:35:1600:35:21 A lot of women want to work on their glutes but are afraid of getting big thighs.

00:35:1900:35:24 They want to lift weights but are afraid of getting bulky. How should they go about it if they want a toned physique?

00:35:2400:35:28 This has been a topic of debate for a long time.

00:35:2800:35:32 If women want to do weight training but are worried

00:35:3000:35:36 or afraid of getting bulky

00:35:3200:35:38 I’d say it’s really difficult, Yeah, very difficult.

00:35:3800:35:44 Honestly, even for men, it’s hard to achieve that.

00:35:4400:35:49 First, we need to talk about genetics.

00:35:4600:35:52 Some people say, “I want to have a body like that.”

00:35:5200:35:56 But the genetic role, like your skeletal structure

00:35:5400:35:59 or the way your muscles build, might be different.

00:35:5600:36:01 So, you might need to adjust your perspective on health first.

00:35:5900:36:03 You are you. You should aim to be the best version of yourself.

00:36:0300:36:08 When it comes to weight training for women, it’s actually something that should be done a lot.

00:36:1300:36:18 Because women have a higher chance of developing osteoporosis than men.

00:36:1800:36:24 Weight training not only helps increase muscle mass,

00:36:2200:36:26 but it will tone your body. It won’t make you look big.

00:36:2400:36:29 Because naturally, women have lower levels of testosterone.

00:36:2900:36:33 That’s why men, when they train, can grow bigger muscles than women.

00:36:3800:36:41 That’s because of what many people call the male hormone.

00:36:4000:36:44 So, for women who are concerned about this, they should slowly adjust their perspective.

00:36:4400:36:50 It takes time to change beliefs and perceptions about this.

00:36:4600:36:52 They need to give themselves time to adjust their mindset.

00:36:5600:37:01 In conclusion, you should still exercise and lift weights.

00:36:5800:37:03 Don’t be afraid that lifting weights as a woman will make you as big as a man.

00:37:0100:37:05 Nowadays, women lifting weights look great and sexy.

00:37:0500:37:10 So, it’s better to exercise. It’s really hard to get bulky from lifting weights.

00:37:1300:37:18 Because, after all, women’s testosterone levels are already lower than men’s.

00:37:1800:37:22 But exercising will definitely make your body look better.

00:37:2000:37:24 And your bones will become much stronger.

00:37:2400:37:29 Now, for some people, no matter how hard they exercise, if they don’t sleep enough, they won’t see muscle growth. Why is this?

00:37:3100:37:38 It goes back to what we’ve been saying all along: the importance of rest.

00:37:3400:37:42 It’s the key.

00:37:3800:37:44 Most people are always searching for magical remedies or supplements.

00:37:4200:37:46 They wonder how to recover faster.

00:37:4600:37:51 But they forget that your body has one mechanism that you don’t have to spend any money on.

00:37:4800:37:53 It’s sleep.

00:37:5500:38:00 During sleep, it’s undeniable that it’s the period when your body systems enter repair and recovery mode.

00:38:0000:38:05 Speaking of sleep

00:38:0200:38:09 there are 3 sleep cycles, averaging about 2-3 hours each.

00:38:0500:38:11 Most people ask if sleeping about 4-6 hours is okay.

00:38:0900:38:14 Actually, it’s okay.

00:38:1100:38:16 But during recovery, it actually only recovers one part, which is the body.

00:38:1400:38:18 But what's missing is the nervous system or the brain.

00:38:1800:38:23 This is why, if you don’t sleep enough, you'll feel tired and recovery doesn’t happen fast enough.

00:38:2100:38:25 Now, how does this relate to muscle building?

00:38:2500:38:32 It's the process of repair.

00:38:2800:38:34 This is the time I mentioned when it’s like someone applying cement, and it starts to work.

00:38:3200:38:36 Now, the body will release various hormones.

00:38:3600:38:40 These hormones help with muscle development and growth, like growth hormone.

00:38:3800:38:42 These hormones are released during sleep.

00:38:4500:38:49 From a medical perspective

00:38:4700:38:51 after lifting weights, the benefits from weight training are already significant.

00:38:4900:38:54 But now, there will be muscle inflammation.

00:38:5100:38:56 When we sleep, for example, during deep sleep and good sleep

00:38:5400:38:58 I emphasize, it has to be deep and good sleep.

00:38:5800:39:03 The body will produce growth hormone, the hormone for growth.

00:39:0100:39:06 It’s a hormone that helps repair the body.

00:39:0600:39:12 Therefore, sleep is the most important period for body recovery.

00:39:0900:39:14 Some people finish weight training, then go party and drink alcohol.

00:39:1400:39:18 You might sleep, but your body won’t repair itself.

00:39:1600:39:21 So, sleep is really important.

00:39:1800:39:23 And the second thing is nutrition.

00:39:2100:39:26 You need to eat enough protein.

00:39:2600:39:30 If you don’t eat enough protein, your body and muscles won’t know what to use to repair.

00:39:2800:39:32 It's like you said, it's like applying cement, but where's the cement?

00:39:3000:39:36 There’s no cement to apply, right?

00:39:3600:39:43 Now, many men go to the gym and work out hard.

00:39:3900:39:45 But with a heavy workload, they don’t have time to exercise 3-5 days, and they’re afraid their muscles will shrink.

00:39:4300:39:48 Can our muscles shrink or disappear?

00:39:4500:39:50 Yes, they can shrink, but it’s not that easy.

00:39:4800:39:53 People tend to think it happens easily.

00:39:5000:39:56 Some people get smaller.

00:39:5300:39:59 They used to have big muscles, but when they stop

00:39:5600:40:01 For example, if they go on a trip for 3-4 days, they come back feeling smaller and weaker.

00:40:0100:40:06 What’s happening during that time is actually the real size of your muscle.

00:40:0400:40:08 Because during weight training

00:40:0800:40:14 for 1-2 days after, what happens is blood retention or swelling in the muscle cells.

00:40:1100:40:16 This makes you feel bigger, fuller, or thicker.

00:40:1600:40:20 That’s why when people train with weights

00:40:2000:40:25 they want to keep going and feel like their muscles are constantly swollen.

00:40:2500:40:32 The condition where muscles shrink or atrophy

00:40:2800:40:36 is actually very difficult to happen.

00:40:3200:40:39 Unless you do nothing at all.

00:40:3600:40:43 To give you an example, if you have a fever and go to the doctor and need to wear a cast

00:40:3900:40:45 after just 2 weeks, you will clearly see the muscle shrink.

00:40:4700:40:51 If you’ve already developed muscles or built muscle mass,

00:40:4900:40:53 it’s not something that will disappear easily.

00:40:5300:40:58 During the first week of stopping

00:40:5500:41:00 what happens is that the muscle size doesn’t decrease.

00:40:5800:41:03 But what you feel is that it becomes softer.

00:41:0000:41:04 This is due to the nervous system signaling.

00:41:0300:41:06 Remember that our body uses two systems: the nervous system and the muscular system.

00:41:0600:41:11 The nervous system is what controls the muscles, telling them to move.

00:41:1100:41:17 When it’s not being activated

00:41:1400:41:19 for example, when you stop exercising for 3-5 days, and the muscles aren’t being stimulated,

00:41:1700:41:22 the body thinks, "If I keep using the nervous system, it’s wasting energy."

00:41:1900:41:25 "So, I’ll shut it down."

00:41:2200:41:28 This means that if someone stops lifting weights for about 3-4 days,

00:41:2500:41:29 when they return to lift for the first time, it will feel harder.

00:41:2800:41:31 But after trying one more set, they’ll be able to lift as usual.

00:41:2900:41:34 Because it has memory, right? Yes, it has memory.

00:41:3400:41:39 And how does it start to lose? Well, of course, strength starts to fade.

00:41:3600:41:41 If you stop for 3-4 weeks

00:41:4100:41:45 Then, after about 8-12 weeks, muscle loss will start.

00:41:4300:41:47 But don’t forget that normally you lose muscle every day.

00:41:4700:41:52 And there’s always microtearing when you use muscles.

00:41:5200:41:57 I want you to think of muscle fibers like our hair.

00:41:5400:42:00 You can’t count them.

00:41:5700:42:03 So, there’s a chance that if you move, it could tear.

00:42:0300:42:07 If you don’t stimulate them with weight training and don’t consume enough protein,

00:42:0500:42:09 these fibers will continue to tear.

00:42:0900:42:15 That’s why, as people get older, they start to gain weight, even though they’re eating the same amount.

00:42:1200:42:17 If they don’t train with resistance or exercise

00:42:1500:42:21 because muscle mass begins to degrade when you aren’t active.

00:42:2100:42:27 If you stay still and move normally

00:42:2300:42:30 there will be small tears that accumulate.

00:42:2700:42:32 On average, it might disappear by about 1-2% per year if you don’t do anything.

00:42:3000:42:36 That number seems small

00:42:3200:42:38 But if you add it up for 2-3 years, it becomes 4-5%, which is a significant amount.

00:42:3800:42:42 This brings us back to why your weight might be increasing.

00:42:4200:42:48 Because when muscle mass decreases, your metabolism slows down, but you’re still eating the same amount.

00:42:4600:42:51 Your weight will go up as a result.

00:42:4800:42:53 But if you start exercising again

00:42:5100:42:55 like after stopping for 3-4-5 days and returning to exercise,

00:42:5300:42:58 At first, you might feel more tired than before.

00:42:5500:43:01 And will you be able to lift the same weights as before?

00:43:0500:43:10 This is why it’s important to track your training.

00:43:1000:43:18 For example, if you stop for 1-2 weeks,

00:43:1400:43:20 you might need to lift the same weight as before you stopped.

00:43:2000:43:24 To reduce the risk of injury.

00:43:2200:43:26 And this will also help stimulate the nervous system to work again.

00:43:2600:43:31 Now, regarding diet, if it were you, how would you recommend choosing food

00:43:2900:43:34 to keep your health strong and long-lasting?

00:43:3400:43:39 Actually, there are many approaches

00:43:3900:43:44 but I think if you stick to a practical approach, you can start by looking at your plate first.

00:43:4400:43:50 You can divide your food into sections, like 2 parts for vegetables,

00:43:4700:43:52 1 part for carbohydrates, like rice or pasta

00:43:5000:43:56 and 1 part for lean protein, like chicken.

00:43:5200:44:02 You could start by adjusting your diet from there.

00:43:5600:44:04 I think the problem is that we have limited time these days.

00:44:0400:44:08 So people end up choosing fast food or something that's easy to grab.

00:44:0600:44:10 That's the first method.

00:44:1000:44:17 Method 2 is reading labels and checking calories.

00:44:1700:44:22 It helps, but I have to say it's not 100% accurate.

00:44:1900:44:25 It's impossible to be 100% precise

00:44:2500:44:30 but it’s one way we can track how many calories we've eaten today.

00:44:2800:44:32 Is it too much? Something like that.

00:44:3400:44:40 I once had a patient come in to talk about weight loss.

00:44:3700:44:42 I told the patient that controlling your diet or choosing food

00:44:4000:44:44 is actually harder than exercising.

00:44:4400:44:51 Because with exercise, for example, the doctor orders just 1 hour a day.

00:44:5100:44:56 But with eating, some people eat all day long.

00:44:5600:44:59 So, you have more time for eating than for exercising.

00:44:5700:45:03 When we talk about weight loss

00:45:0300:45:08 80% should be focused on food. It’s really more important.

00:45:0600:45:10 First, pay attention to the nutritional value of your food.

00:45:0800:45:12 Try to avoid processed foods.

00:45:1200:45:17 Foods that are unhealthy

00:45:1500:45:20 and sugar. I’ve said many times that sugar is bad for the body.

00:45:1700:45:23 Or sugary drinks like sodas.

00:45:2000:45:26 And alcoholic drinks.

00:45:2600:45:32 If possible, I recommend eating food that comes from nature as much as possible.

00:45:3200:45:36 Avoid processed food or convenience store food.

00:45:3300:45:38 Because those may have been stored for a long time or prepared a long time ago.

00:45:3800:45:44 So, fresh food is the best for your body.

00:45:4400:45:50 Do you have any techniques or tips for choosing proteins to help our body grow?

00:45:4600:45:53 You might want to check if you're getting enough protein each day.

00:45:5300:45:58 There’s a guideline that suggests multiplying your body weight by the amount of protein in grams,

00:45:5600:46:00 which is about 0.8–1 gram.

00:45:5800:46:02 This is for general people.

00:46:0200:46:06 For maintenance or keeping it steady.

00:46:0400:46:08 This is for people who don’t exercise, right? Yes, for general people who don’t exercise.

00:46:1200:46:19 For people who work out in the gym, increase it to 1.2–1.6 grams per body weight per day.

00:46:1900:46:25 For weight lifters aiming to build muscle, increase it to 1.6 grams or more, up to 2 grams.

00:46:2500:46:29 That’s why you need more protein.

00:46:2900:46:34 For athletes, protein requirements might be even higher.

00:46:3400:46:38 And if you're in a fat loss phase

00:46:3600:46:40 you should aim for about 2 grams per body weight.

00:46:3800:46:42 During fat loss, you eat the same amount of protein but cut down on carbs, right?

00:46:4200:46:47 Yes, reduce the proportion of other nutrients.

00:46:4500:46:49 When we talk about nutritional structure,

00:46:4700:46:52 it’s divided into carbs, protein, and fats.

00:46:5200:46:56 You’ll notice that carbs have a wide range.

00:46:5300:46:59 You may need to reduce the proportion of carbs and increase your protein intake.

00:46:5900:47:04 Supplements like BCAAs, which help build muscle,

00:47:0100:47:07 you eat them, and they just get excreted, right?

00:47:0700:47:13 BCAAs are amino acids.

00:47:1100:47:16 They come from the meat we eat.

00:47:1800:47:23 Now, I need to explain that some BCAAs might be missing certain amino acids.

00:47:2300:47:32 Because in reality, you should prioritize getting nutrients from natural food sources first.

00:47:2800:47:35 Then, if you feel something is lacking or needs supplementation,

00:47:3500:47:39 you can take supplements, but in my opinion, it’s not really necessary.

00:47:3700:47:41 If you’re already getting enough, otherwise you’re just wasting money for no reason.

00:47:4100:47:46 Because BCAA stands for Branch Chain Amino Acid.

00:47:4300:47:48 There are only 3 of them.

00:47:4800:47:54 But actually, muscles don’t just need these 3; they need over 20 different amino acids.

00:47:5400:47:59 So, getting protein from real food already covers it.

00:47:5800:48:01 Unless you’re eating too little protein or not consuming animal products,

00:47:5900:48:03 for example, vegetarians might need BCAAs as a supplement.

00:48:0300:48:07 BCAAs might be an option to supplement in that case.

00:48:0500:48:10 Because most of these amino acids are found in animal products, not so much in vegetables.

00:48:0700:48:13 So, it might be suitable for certain groups of people.

00:48:1000:48:15 Some might think of it as a special supplement

00:48:1500:48:21 but really, it’s just a supplement. If you’re lacking, it might be necessary.

00:48:1800:48:23 As you mentioned, it’s for certain groups of people.

00:48:2300:48:28 Did you know that just rinsing your mouth with sweet water or electrolyte water can boost your exercise endurance?

00:48:2500:48:30 It’s called carbohydrate mouth rinsing.

00:48:3000:48:36 You might have seen it on TV or during marathon football races.

00:48:3200:48:38 Athletes often rinse their mouth with water.

00:48:3600:48:41 And then spit it out.

00:48:3800:48:43 Actually, there’s a reason behind it.

00:48:4100:48:45 Whether it’s sweet water or electrolyte water, it contains sugar.

00:48:4800:48:53 Athletes put sweet water in their mouth, just rinse it around for about 10 seconds, then spit it out.

00:48:5000:48:55 By having sweet water in your mouth, it’s like tasting sweetness.

00:48:5500:49:00 When the sugar goes in, it sends signals from your mouth to your brain.

00:49:0000:49:06 This makes you feel more motivated.

00:49:0300:49:08 It’s like giving your body a reward.

00:49:0600:49:11 Your body gets more energized and stimulated.

00:49:0800:49:13 Then, you just spit it out.

00:49:1300:49:17 You might wonder why not just swallow it.

00:49:1700:49:22 First, you need to understand that some people need to continue exercising, they need to keep running.

00:49:2000:49:24 So, swallowing it might make their stomach feel heavy.

00:49:2400:49:29 And some people, for health reasons,

00:49:2700:49:32 they don’t want their blood sugar levels to rise too much or their insulin levels to spike.

00:49:3200:49:39 So just holding it in the mouth for a bit, about 10 seconds, then spitting it out is enough.

00:49:4100:49:46 For workouts lasting more than 30 minutes, you can do this.

00:49:4300:49:48 But rinse every 10 to 15 minutes.

00:49:4600:49:52 Rinse and spit, rinse and spit.

00:49:4800:49:53 This is another technique that can help boost your energy.

00:49:5600:50:01 As we’ve said from the beginning, exercise is very beneficial for our bodies.

00:50:0100:50:05 Today we've learned a lot from you.

00:50:0300:50:08 Is there anything you’d like to leave as a final message to the audience?

00:50:0800:50:13 Don’t compare yourself to others. Everyone has their own goals.

00:50:11.07900:50:15.599 I always like to say that everyone has different steps on the ladder.

00:50:1300:50:17 Because each person has different limitations.

00:50:1500:50:19 You may want to lose weight

00:50:1700:50:21 and wonder why your friend can lose weight faster than you.

00:50:2100:50:27 You might not know that their background or circumstances could be more flexible than yours.

00:50:2400:50:30 You might have more limitations or other factors.

00:50:3000:50:35 The main thing is to take it day by day, do it bit by bit, little by little.

00:50:3300:50:39 The key is consistency.

00:50:3500:50:41 Like I said, make exercise a part of your life, just like eating meals.

00:50:3900:50:43 When it becomes part of your lifestyle,

00:50:4100:50:46 it will contribute to overall health improvement.

00:50:4300:50:49 It will help you live a better quality life.
