This is a misunderstanding. Well, there is no such thing as China/Asians having difficulty in training muscles. I'll say it at the end.
Why are there so many muscular men with extremely strong muscles in America? I won't talk about cultural differences on this issue, just from an objective point of view.
First, the principle of muscle growth
First of all, I want to talk about the principle of muscle growth.
I copied and pasted this principle seven or eight times in Zhihu's answers to various fitness topics. Because this thing is not clear, most problems are out of the question.
In fact, muscles don't grow when you exercise. During exercise, your training will destroy muscle fibers, and protein supplemented at home will be used to supplement the damaged muscles. In the process of replenishment, the original muscle fiber will gradually become larger, so that in your next training, the muscle fiber can bear more weight. This is the basic principle of muscle growth.
So in fact, muscle growth is nothing more than two points, one is exercise, and the other is diet.
If a person does not exercise, the probability that she/he has strong muscles is 0%, unless he/she uses steroids, testosterone and other hormones. And a person who only exercises and doesn't supplement enough protein is unlikely to have many muscles.
Second, the vast majority of China teenagers lack exercise/protein intake.
I have personally experienced the habits of people around me for more than 20 years, giving me the overall feeling that thin people in China are generally thin and have no muscles. Even people who exercise regularly feel that they don't pay attention to the maintenance of muscles and the intake of protein, so muscles are easily lost. Most people have no idea about protein and carbohydrates in their diet.
It is precisely because there is no concept of protein, so those who can only be regarded as normal muscles and have sufficient protein intake are often people with excessive body fat content, which is commonly known as chubby people or real fat paper. ...
Therefore, most people in our country are in a state of lack of protein.
So even with enough exercise, it is difficult to get enough muscles.
Let's compare here.
Americans started systematic fitness very early. For Americans, most people spend a long time in the gym-this is also caused by social and cultural factors. Generally, students who are popular at school tend to be good at sports, not geeks with good grades. There is nothing to say here. Don't say a few years. In fact, as long as you systematically practice in the gym for one year, it's completely different from what you haven't practiced. As long as a person starts to exercise at the age of 17, by the time he is 20, he will be very, very strong, although his body is not tough. Americans 15, it is actually very common to start physical exercise at the age of 6.
The protracted nature of exercise. When watching Good Will Hunting, I was deeply impressed that the protagonist and the psychological counselor were talking about fitness. The old psychological counselor said that he had been practicing weightlifting for a long time (weightlifting like the Olympics)-in fact, if you look at American movies and TV series, you will find that most of the old people in them are strong, and there are few old people with thin bodies. This is entirely the result of their long-term exercise and attention to their health, not born.
Apart from exercise, as far as diet is concerned, this is even more incomparable. Most people in China still have a knowledge of "eating only one egg a day", and a knowledge of protein powder that "eating too much will harm your health" and "eating too much will harm your kidneys"-this side effect on your health has been completely exaggerated by several orders of magnitude (add here: you can eat more egg whites, and one or two yolks a day is enough. Americans ... in pursuit of absolute strength and figure, they began to take steroids-even though they were sure it did have side effects on their health.
Atmosphere. Gyms in China can be operated for more than five years, and many can make profits, but few can. The whole industry is in chaos. Some gyms run away after two years of opening. Many coaches are actually salesmen. People in China like to run in the playground or the street, instead of going to the gym.
Lack of fitness knowledge. One thing that should not be ignored is that. Even in China, many students in college physical education or middle school physical education schools do not have systematic fitness knowledge.
