A new study in The BMJ has identified aerobic exercises such as walking, cycling, and swimming as the most effective ways to ease pain and improve mobility in people with knee osteoarthritis. After reviewing more than 200 clinical trials with over 15,000 participants, researchers found that these activities consistently outperformed other exercise types for reducing discomfort, improving gait, and enhancing quality of life.
While strength training, stretching, and yoga also offer benefits, the study found that aerobic exercise should form the foundation of any osteoarthritis care plan. Moderate-certainty evidence showed that regular aerobic activity not only reduces pain in the short and mid-term but also supports long-term joint function and well-being.
Experts say the findings give patients and doctors clearer direction for managing knee arthritis. For most people, starting with low-impact activities like walking, cycling, or swimming is the best approach, with other forms of exercise added later for additional support. Even small, consistent steps toward daily movement can make a big difference in comfort and mobility.
