The Trainer: Tracey Mallett, star of the DVD Super Body Boot Camp: Burn It (RazorFitness.com), created this calorie-torching circuit of jumping moves (aka plyometrics) that promises to zap up to 150 calories in only 15 minutes. "Short bursts of cardio get your heart rate up and fire your muscles so you burn calories quickly," Mallett says. And these exercises work multiple muscles to help you tone from head to toe.
The Plan: Complete each move in the order shown without resting. To speed flab-fighting, repeat with a two-minute break between circuits. Do it four times a week to see a firmer physique in a month.
Bonus: This routine counts as cardio.
Technique Tips: Start slowly, then pick up the pace. "Your goal is to do as many reps as you can in the time allotted without sacrificing form," Mallett says. Oh, and easy on the knees, please. Always land with your joints soft to prevent injury.
