Contrary to earlier beliefs, exercise is now recognized as essential for managing fibromyalgia and CFS. Regular physical activity strengthens muscles, controls weight, and promotes an active lifestyle. Range of motion, strengthening, and aerobic conditioning exercises have been found to be safe and beneficial for most patients.
HOWEVER…many are unable to exercise, as it is too exhausting and painful. In this case, if possible, it is beneficial to do light movements / as much as you can manage. This can be as simple as movements whilst in bed.
