Lie face down with your hands directly under your shoulders. Legs should be straight out with toes pointed. Gently exhale, pull your bellybutton towards your spine and push your hips into the floor. With your shoulders pressed down and back, curl your chest away from the floor. Hold for 15-30 seconds, then gently lower yourself down, lengthening the spine. Repeat. (This exercise should not hurt your back! If it does, try not extending as far. If it still hurts, stop.)
