Three 15-minute workouts that combine Tae Kwan Do, kickboxing and military-type drills.

Intermediate exercisers who enjoy a bit of jumping around (in other words, it's not for those with bad knees). You'll need a set of light (3–5 lb.) weights for the second segment.

While these three workouts won't make you feel like you're grunting through basic training, they will help you work up a sweat. Like most Method tapes, these sessions are not for purists — the moves are based on kickboxing, Tai Chi and Tae Kwan Do, but don't adhere to strict form. Instructor Tracey Mallett may annoy some people (she has a strange, lispy accent), but at least she invites you to have fun while working you reasonably hard during these three 15-minute segments. The first and third segments use intense cardio and kickboxing drills; the second segment adds in some work with dumbbells for just a few moves. Expect to do push-ups, jumping jacks, kicks and punches. The biggest downfall of these workouts is that none of them have a decent warm-up or cool down — you'll have to add those in yourself. The good part of this tape is that you can do one, two or all three workouts, depending on your time and energy. While there are choreographed moves to learn in Cardio Boot Camp, those who dislike dancey aerobics may enjoy its more straightforward approach.
