Muscle soreness is generally because the exercise load is greater than your previous exercise load, and your body can't adapt at once. The cause of muscle soreness is the accumulation of lactic acid in physical strength. There are many ways to eliminate it, such as massage, hot compress and stretching. The easiest way is to exercise, and the amount of exercise should not be too large, which is generally one-third of your usual level. Muscle pain is not a disease. It will be all right in a couple of days. If you don't do much exercise, it's normal to have pain for a week. If you feel the pain of a torn muscle, it's not sore. You can also go to the gym in the future, and at the same time ensure the number of times you go, two or three times a week. The amount of exercise should be controlled at about 60% of your physical endurance, and the training time should be 1- 1.3 hours, which should not be too long.
