Through exercise, a person can first improve the body's muscle mass and increase the body's muscle mass. At this time, the muscles of the body are growing in quality and quantity. If a person doesn't exercise for a long time, the muscle quality will first decline, which is mainly reflected in the fact that muscle strength and endurance are not as good as exercise.

If you don't get exercise, your muscles will start to shrink and the number of muscles will decrease. Therefore, if a person does not exercise for a long time, his muscles will decrease. Exercise can not only improve muscle mass and increase muscle mass, but also delay muscle atrophy caused by age.
