This "toning" video would be a joke, except that you really could get hurt following it. In fact, when Shape Your Body first came out, fitness expert Peg Jordan, author of Fitness Instinct, appeared on CNN warning viewers about the risks of this video. "I received a call from a chiropractor who had treated 12 patients' back injuries from that video alone!" she recalls. If you've got to have this one, watch it only, don't do it. --Joan Price
