Swimming is often considered one of the best exercises for people with knee pain. Because water supports body weight and reduces stress on the joints, swimming allows many people to stay active without the impact associated with walking, running, or jumping.
For people with arthritis or chronic knee pain, swimming can help improve mobility, strengthen muscles, and maintain cardiovascular fitness while minimizing stress on the knees.
However, certain swimming strokes and techniques may be better than others depending on the cause of your pain.
