1, muscle gain is actually to put aside the reasons such as sarcoplasmic reticulum and muscle congestion. Let's look at muscle growth without these reasons. In fact, muscle growth is inseparable from excessive recovery. It can also be said that excessive recovery is a principle of muscle growth.

2. Excessive recovery refers to a process in which our muscle fibers slowly recover after being torn in constant exercise and fitness, and then become muscles. In fact, we can also imagine this process as a tree. Basically, after peeling off a layer of skin, a tumor will grow, and then the branches will definitely be thicker than the original ones.

3. Of course, muscles will not last long, but they will grow, so the principle is similar. This example is also for your understanding.
