Try the new Supermoves! Just one of these is better than two standard-issue exercises. Do a few and you'll cut your workout time in half.More
This move is more effective for your abs than the average crunch because the lower ab muscles are working to stabilize your spine at the start and to lift and lower your tailbone at the end, explains Andrea Mitchell, a Pilates and yoga instructor based in New York. Keep the movement slow and controlled to get the most out of each rep.
A: Lie flat on your back, pulling your abdominals in, with both legs extended straight up toward the ceiling, toes pointed, as shown.
B: Exhale and tighten your abdominals while you lift your tailbone 2 to 3 inches off the floor. Slowly lower back down to starting position (count to 3 so you don't plop down too quickly). Work your way up to 10 reps in a row.
"This move is intense enough that many athletes use it as a warm-up," says Meggan Berg, group fitness director of ClubSport Oregon. "The faster you move your legs, the more calories you'll burn."
A: Begin on the floor in a push-up position, hands directly under shoulders and legs extended behind you, as shown.
B: Bring left knee as close to chest as possible, as shown, then quickly switch legs, pulling right knee in while extending left leg back. Continue for 30 seconds, alternating legs the whole time.
