To make the skeletal muscle get a good workout, we have to do the appropriate weight-bearing exercise, only to make the skeletal muscle myofibroblasts constantly destroy the growth, and then destroy and grow again, so that the skeletal muscle cells gradually physiological hypertrophy. The best way to exercise is strength training, relative to the body to do the maximum weight impact training, used to destroy skeletal muscle cells, so that skeletal muscle cells gradually due to stress stimulation and had to produce physiological hypertrophy. The specific action should be gradually standardized to the regular gym, gradually make the skeletal muscle through proper exercise and physiological hypertrophy.
