Knee pain caused by exercise is inevitable, and the key is to find the correct maintenance method-"squatting" or "squatting against the wall". This static exercise method has a good effect on the daily health care and maintenance of knee joints, ligaments and leg muscles, and can avoid unnecessary injuries in daily exercise. "Small squat" can be done after a certain period of daily exercise, and "wall-sticking squat" is generally practiced every day after knee joint or leg ligament or muscle injury.

The detailed contents and specific explanations of "semi-squatting" and "semi-squatting against the wall" can be found under "Encyclopedia".
