Cardio Kick Box is a high-energy aerobic workout designed to keep you moving and boost your fat-burning capabilities while at the same time giving your muscles a day off from wither-training. Jillian recommends doing Cardio Kick Box once a week, in the middle of the week, to break up your regular exercise program. this program is to get out there and have some fun, and keep your body moving.If you’re envying the six-pack abs on Jillian Michaels, trainer from NBC’s The Biggest Loser and self-proclaimed “TV’s toughest fitness guru,” look no further than her Shape-Up Backside exercise DVD for an intense high-impact workout. Michaels keeps your body moving (though she herself skips out on half the exercises) with hammer curls, oblique raises, step ups, planks, and a move called The Superman destined to tone your back, biceps glutes, hamstrings and abs. There’s a lower-level option, but Michaels likes to “kick your butt,” as she says, to get you to feel the burn. Shape-Up Backside’s DVD features include printable diet/exercise logs, nutrition tips and recipes. It requires two props: a bench-style exercise step and light dumbbells, which may make it difficult for beginners. But if you give it a try, even in the comfort of your living room you’ll think you’re in a gym — trainer yelling in your ear and all. — Ellen A. Kim
