Moderate exercise should not cause a problem and will help your overall health and well being. If you are on prednisone weight bearing exercises have a lot of value to stave off bone loss. Just listen to your body and back off if you do too much.
I work out 4-6 times a week and my workouts are 1-2 hours and usually vigorous. If I am tired I do less or take the day off. Never had any problems other than falling asleep in my chair at night.
I believe that many chonically ill people talk themselves into doing less and suffer as a result. Exercising or even taking a short walk is difficult when you have weakness or chronic fatigue but if you can make yourself do it, even on a very modest scale, you are usually better off. Of course, discuss it with your doctor.
