Strengthen and tone your midsection with this simple and effective move that doesn't require endless repetition. Make sure your form is precise and that you use complete control to get the maximum benefit.
-- Karen Voight
1 Lie face up on the floor (or exercise mat), both legs straight in front you. Inhale and, with both hands, hug your left knee, bringing your chest and face as close to your knee as possible. On an exhalation -- keeping your chest and head up -- raise your right leg off the floor a few inches. Pause and focus on strongly contracting your abdominals to maintain the upper-body curl.
