Sit upright with your elbows out fist together. Using your abdomen, seat, and lower back, curl back as though you are rowing a boat, hands into sternum. Your lower back will curve like a letter C. Hold the body still and open the arms out. Keep your body still and press your arms backward. Begin to fold forward, head toward knees, constantly scooping the stomach away from the thighs as the hands travel back and come together. With control, open your arms and circle them as high and wide as your shoulders comfortably allow. Return to starting position.
