I am here as a person who has also practiced in the gym, so let's correct this view. What a person does depends on the concerted efforts of all or more muscle blocks, that is to say, attention should be paid to coordination. Simply put, you can't just develop a muscle mass, but you can do it as a whole, as well as your reaction nerves and so on, which is why many people in the gym will practice other parts of the muscle mass after touching one muscle mass, because
Moreover, there are skills. Muscle mass alone is not enough. Why do we see that Huo Yuanjia, whose muscle mass is obviously not as big as that of foreign giants, can beat these giants when watching Huo Yuanjia's movies? It is because of their skills that they know how to give full play to their strengths. And I don't know if you have seen Muay Thai. It is by combining his body and skills that he can exert great strength. Or, if you are interested, you can watch the video of Bruce Lee showing his strength, and you will understand that if you know the skills and the power of exerting strength.
Therefore, I suggest that if you practice muscles, you'd better pay attention to the way and know how to coordinate in all aspects.
