After being stimulated by a certain load, muscle cells produce anaerobic respiration and lactic acid (C3H6O3) due to the increased demand for oxygen, which is the cause of soreness. It can be metabolized by reacting with oxygen. Pain can be relieved by aerobic light exercise, such as jogging, aerobic and so on. Combining anaerobic exercise with aerobic exercise can make you adapt quickly.

So before doing strenuous exercise every time, the body must be active. It is best to run at a constant speed of 2000M or at a variable speed of about 800M, and then move joints or ligaments to prevent muscle strain.
