Stand with your feet a bit wider than hip width. Rotate your hips and shoulders from side to side, allowing your relaxed arms to flap against your sides like empty coat sleeves, with the hands gently striking the body at the hips. Let your head join the motion, turning to look over one shoulder, then the other. Coordinate breath and motion, exhaling as you twist and inhaling back to center. Keep your spine erect and your hips and shoulders rotating from side to side as if in a barrel (as opposed to swaying). As you twist, curl your hands into loose fists and gradually lift them to bellybutton height, then chest height, then shoulder height, moving the stretch progressively up the spine. Lower your hands the same way you lifted them, returning to your relaxed arms flapping against your sides. Slow your twists until you eventually stop. Take a deep breath in, then let it out with an audible sigh.
