Banish Ab and Back Fat

Group 1: Rocket + Knee-Cross Crunch

Blame it on low riders and skimpy tops, but lately women everywhere seem to be lamenting the roll of jiggle that bulges over the waistline or bra strap. The solution to belly and back fat? This combo routine from Ellen Barrett, creator of the Pick Your Level: Weight Loss Pilates DVD (that's her below), which pairs high-energy plyometric exercises with core-toning Pilates moves. "You'll sculpt your entire midsection from every angle while burning fat," she says. Do it two or three times a week and your whole torso will be leaner in just 30 days.

How It Works: Do each plyometric/Pilates combo in the order given, taking 10 seconds to rest between each series. If time allows, repeat the sequence twice.

Fat Blaster: Rocket

Stand with feet together, knees slightly bent and abs engaged with arms at your sides. Jump up as high as you can, using your arms for momentum, and land softly with knees slightly bent. Do 10 reps, pausing briefly between each one.

Core Toner: Knee-Cross Crunch

Stand with feet together. Raise left arm overhead and place right hand on hip (not shown). Keeping your torso upright, exhale and touch right knee and left elbow together across the body. Inhale and return to start. Repeat 10 times. Switch sides.
