Belly Basics

Lie face up on the floor, feet together on an exercise ball, knees bent. Contract your abs, pulling your navel toward your spine and lifting your hips until your upper body forms a straight line from shoulders to hips [A]. Using your abs to maintain the position, draw your right knee in toward your chest [B]. Hold for three breaths, lower and switch to your left knee. Work up to 3 times with each knee.
