The word “exercise” is usually associated with strenuous activity, which would be too much for most fibromyalgia patients. Instead, try to think of exercise simply as movement. Try to focus on moving your body more. If all you can do at first is walk to the mailbox, that's fine. The important thing is to move. Too much inactivity, whether lying down or sitting, can actually increase your pain. During the day, try to move frequently, even if it’s just to walk to another room and back.
