Bodybuilders have an expression, "No pain, no gain," meaning if you don't feel sore after a workout, the results may be unimpressive. For arthritis sufferers, however, the pain from their condition may discourage them from exercising at all.
This really is a no-gain situation because studies have shown that exercise can help people with osteoarthritis improve their range of motion, strengthen their muscles and get a better night's sleep. And it can actually reduce pain.
Exercises aimed at increasing flexibility are especially beneficial. These include nonimpact, gentle routines such as yoga, tai chi and stretching. The National Institute on Aging has a downloadable tip sheet with several flexibility exercises at nwsdy.li/flexibility.
As always, don't begin any new exercise routine without first checking with your physician.
