Get ready to whip off your cover-up: This workout, created exclusively for Women's Health by Rachel Cosgrove, C.S.C.S., owner of Results Fitness in Newhall, California, combines fat-burning cardio with moves that target your entire core rather than individual muscles, so you'll burn more fat while toning up.
DIRECTIONS

Do these workout moves three nonconsecutive days a week. Start with the Basic Workout (moves 1-4) to prime your muscles. After three weeks, you'll be ready to graduate to the Advanced Workout (moves 5-8). For maximum fat burning, perform the exercises as a circuit: Do one set of each move in the order shown, resting for 30 seconds between exercises. Then rest for a minute and repeat the circuit from the beginning.
