There are two possibilities for joint ringing during exercise. One is normal joint activity, noise and no pain. The other is because the joint itself or its surrounding tissues are diseased, and most of them are accompanied by pain. Physiological joint noise is produced by normal joint activities and is harmless to the body. More common in beginners and people with weak muscle strength around joints. With the improvement of fitness level, muscle strength, ligament strengthening and coordination of movements, this sound will be alleviated.
