Do 12 to 15 reps of each move in the order shown. Between each exercise, do a cardio burst—2 minutes of jumping rope, marching or jogging in place, stair climbing or stepping, or doing jumping jacks. Remember to warm up and cool down by marching or stepping side to side in place for 3 to 5 minutes at the beginning and end of your workout.

How to Buy a Ball
Most people need a 22-inch (or 55 cm) stability ball. If you’re under 5-foot-1, choose an 18-inch (or 45 cm) one, or a 26-inch (or 65 cm) ball if 5-foot-8 or taller. They’re available in sporting goods stores (about $30) or online. We like the Gymnic Plus because it’s made with burst-resistant, latex-free vinyl, and if punctured, it will deflate slowly.

Lie faceup with calves resting on ball, arms at sides. Press legs into ball, squeezing it between calves and thighs. Contract abs and lift hips 3 to 6 inches off floor and pull knees toward chest. Hold for 1 second, then lower. Cardio burst: 2 minutes.
- Make it easier Contract abs and just lift ball off floor, keeping hips down.
- Make it harder Keeping neck in line with spine, lift head and shoulders off floor as you raise hips. Hold, then lower both upper body and hips.
