BELLY BLASTER: Torso twists
Sitting with your knees bent, feet on floor and hands on your hips, draw your abdominals in. Lean back slightly and soften your back, making a slight C-shape with your torso. (The farther you lean back, the more challenging the exercise.) Next, rotate your entire torso (not just your shoulders), starting at your hips, to your right side. Return to the center, then turn to the left. Return to center and repeat for 20 to 30 seconds.
