Jogging, skating, or rowing can be good exercises for people with mild COPD -- and fun ways to avoid workout boredom. Some activities do double duty, like water aerobics, which is good for COPD and arthritis. For beginners, a pulmonary rehab program is a good, safe place to start. Some people may need to avoid push-ups, sit-ups, or heavy lifting. Ask your doctor what's right for you.
