Firmer Abs...

A firm, jiggle-free belly—everybody wants one. Focusing only on the front, outer layer, as ordinary crunches do, won't shrink its size. Do these exercises three times a week, and you'll have a slim, sexy, bareable tummy!

Diagonal cancan - Targets: Sides (obliques)
Sit with legs together about a foot off ground, knees slightly bent. Keep palms on ground at sides for balance. Holding feet up, tip knees to left as you rotate torso to right (as shown). Return to start, then repeat in opposite direction to complete one rep. Do 12 reps.

T balance on ball- Targets: Inner corset, entire midsection
Balance with upper back on stability ball, knees bent, abs tight, torso parallel to ground. Extend arms at sides. With feet planted, roll right until you feel wobbly (as shown). Squeeze abs to roll to opposite side for one rep. Do 12 reps.

Long torso hold - Targets: Inner corset
Lie faceup with arms extended behind head. Lift shoulder blades and legs, feet together, to form a bowl shape (as shown). Exhale and pull in abs, pressing lower spine against ground. Inhale, then exhale as you shorten the space between bottom ribs and hips. Continue for 20 seconds. Repeat five times.
