If you try it
Search for an instructor who has experience working with people with arthritis, Matthews adds. In addition to a general fitness certification, the instructor should have experience teaching each form of exercise incorporated in the workout.

Look for a class that includes a form of gentle, flexibility-enhancing exercise, such as Pilates or tai chi. “You’ll improve your range of motion, which can ease arthritis symptoms and make everyday tasks easier,” Matthews says.

Let the instructor know that you’ve never done the workout before, and tell her you have arthritis and may need to modify some moves. “A good, experienced instructor will monitor your progress and make helpful suggestions without being pushy or making you feel singled out,” says Matthews.

Go slowly. “Be mindful of your joints and work toward learning your new workout rather than attempting to do the highest impact you can or trying to keep up with more experienced exercisers,” says Matthews.

Doing a DVD? Look for a workout that includes a beginner skill level or modifications.
