Skeletal muscle is the main muscle tissue of the body and is the main structure responsible for the movement of various parts of the body. Low skeletal muscle mainly refers to the fact that the proportion of skeletal muscle in the body weight is lower than normal, and this situation is mainly improved through exercise and dietary changes. Generally eat more protein-rich diet such as beef, eggs and dairy, because these foods can be better absorbed and can be effectively converted into muscle tissue, in addition to the appropriate supplementation of vegetables and fruits and other high vitamin diet to meet the normal needs of the body. On this basis, gradually increase anaerobic exercise, such as dumbbells, barbells and other exercises as well as running exercises for the lower limbs, which can effectively promote the growth of muscle tissue and increase the capacity of skeletal muscle.
