Flapping muscles won't make them bigger and bigger. In order to gain muscle, you need a lot of stimulation. Beating and exercise can cause muscle fiber damage, but it can be recovered by absorbing nutrients, but these nutrients will not be converted into muscle, but into fat. Beating muscles is mainly to improve the contraction speed and hardness of muscles in the training area.

Will the beating muscles make them bigger?

Generally speaking, beating muscles will not make them bigger and bigger. The principle of muscle augmentation is to thicken the original muscle fibers. In order to achieve this goal, various hormones and genes in the body need to be changed through heavy stimulation, so that the body's anabolism increases and catabolism decreases, and the nutrients in food will be absorbed by the body and reorganized into muscles.

Studies have shown that both external force and exercise may cause muscle fiber damage, but supplementing nutrition after exercise can achieve muscle recovery or excessive recovery. The nutritional supplement after external impact may not be converted into muscle, but into fat.

Why do some people beat their chests and feet after exercise?

In some sports, the method of hitting muscles is used to exercise, such as hitting abdominal contraction training in boxing and golf, but they are mainly to improve the contraction speed and hardness of muscles in the training area. So far, there is no evidence that this training method can make muscle grow bigger.
