Lie on your back. Bend your knees and plant your feet about hip-distance apart. Place your hands at your side. Exhale and pull your belly button in toward your spine as you gently raise your torso by bending your hips and waist. Lift up until your torso is just inches from your thighs and your hands can touch your toes. Inhale and control your return to the start position to complete one repetition.
