Power 90
beachbody.com $59.85
Pros: “Solid sweat!” (cardio) and “sculpt!” (weight training) routines led by the likable Tony Horton.
Cons: The cardio routine’s series of intense “power yoga” moves require proper body position, virtually impossible for anyone lacking prior yoga training.
The Firm
firmdirect.com $89.95
Pros: For some women, the we’re-all-well-toned- sisters vibe will be comforting.
Cons: For some women, the we’re-all-well-toned- sisters vibe will be sickening. And, it’s humiliating using something called “the fanny lifter” (it’s a step).
Tae Bo
taebo.com $34.95
Pros: The grand-daddy of infomercial fitness, Billy Blanks, does deliver surprising results with simple, easy moves. Perfect for beginners.
Cons: The advanced tape is a killer. If you can do the shorter novice routine twice in a row, you might be ready to move up.
Winsor Pilates
winsorpilates.com $39.90
Pros: Clearly explained muscle-toning exercises that don’t require any special equipment.
Cons: Other than the models’ drab green unitards? With pilates, you don’t get the perverse joy of feeling sore or the fun of working up a really good sweat.
