If lupus has you on the sidelines rather than in the middle of the action, this new low-impact exercise program, designed specifically for people with lupus, may be “just right” for you. Guided by a licensed A.C.E. instructor who also has lupus, this DVD offers a gentle fitness routine that you can practice in the comfort of your own home. The goal is not to become a super model but to get moving—and to improve your well-being in the process. DVD, 27 minutes.
