Muscle-building equation - understand muscle building in one minute fitness

1. The principle of muscle growth

The human body's muscles are composed of muscle fibers, and the number of muscle fibers is born. To increase muscle, you must thicken the original muscle fibers through exercise

During the exercise, the muscles will be severely damaged. At this time, we need to supplement a lot of protein to repair the damaged muscles. When the damaged muscle fibers completely heal, the muscles will become thicker.

Secondly, muscles contain myoglobin, which is a place to store oxygen. The muscles increase greatly after exercise, so what is needed for muscle activity The oxygen will be supplied repeatedly. Usually, there are only 30-270 capillaries open on the cross section of muscles per square millimeter, and the rest are closed. During exercise, as many as 2,000-3,000 capillaries open. If you have a long period of exercise, these open capillaries in the muscles will also increase greatly, and the muscle fibers will become thicker, which will make the muscles more plump.

2. Muscle growth is restored through excessive recovery. The three keys to excessive recovery are: reasonable training, reasonable nutrition, and reasonable rest time

We use a triangular relationship network to express , that is, "First perform muscle exercise, supplement nutrition and rest." This is a cycle that will keep muscles growing.

We must ensure that these three elements can be executed so that our muscles will grow faster than ordinary people.

Muscle fibers will be damaged when exercising. Replenish protein and muscles will be repaired. When the damaged muscle fibers heal, the muscles will become thicker.

On the contrary, if the damaged muscle fibers are ignored and do not have proper nutritional supplements, the muscles will become thinner and more tired
