U.S. News & World Report reports exercise improves the symptoms and progression of osteoarthritis, as it lubricates the joints; replaces damaged cells with healthy cells; strengthens muscles; reduces excess body weight; and relieves symptoms of depression and anxiety.

U.S. News & World Report spoke to William Behrns, PT, DPT, OCS, physical therapist at HSS, who explained exercise stimulates the production of synovial fluid, which reduces friction to prevent further damage to the cartilage and bone. “Synovial fluid also prevents the collection of inflammatory proteins within the joints that can lead to pain,” said Behrns.

According to Behrns, stronger muscles ensure better protection of the joints. Maintaining a healthy body weight is also important, to ensure the knees and hips aren’t put under excess stress. “Joint stresses are directly related to the amount of weight placed on the joint during an activity," cited Behrns. "The less you weigh, the less joint stresses will exist." Additionally, Behrns noted for every pound lost results in a four-fold decrease in stress placed on the knee.
