Exercise seems to provide both physical relief and psychological benefits. For example, it prevents the muscles from shrinking, while inactivity encourages both loss of muscle tone and bone deterioration. Too much exercise, however, will cause more pain in those with rheumatoid arthritis. One form of exercise that's effective and soothing is hydrotherapy, or movement done in water. It allows freedom of movement and puts less stress on the joints because nearly all of the body weight is supported by the water.
Doctors highly recommend swimming, too.
If you begin to hurt, stop and rest or apply ice packs. The following exercise suggestions may provide relief. Choose exercise routines that use all affected joints. Keep movements gradual, slow, and gentle. If a joint is inflamed, don't exercise it.
