If you have hip arthritis, work on building up the muscles in your outer thigh for added support. Lie on your pain-free side and lift the leg with arthritis up about six inches, hold for two or three seconds, and lower it again, Humphrey says. Start with one set of 10 repetitions and build up to three sets. Repeat on the other side unless it is too painful. This exercise can aggravate your symptoms if you have hip pain from bursitis.
