The work itself is simple. Take a sore back and by resting it on the grapefruit-sized Miracle balls and letting your body sink into them, you're unworking the muscles that hurt.
Pain and tension drain out of the body.
Petrone shows how proper breathing (which she demonstrates) works in conjunction with a range of exercises that call for placing the miracle balls under the back, head, knees, hip, elbow (wherever there's pain) and then resting, rolling, or rotating on them.
She points out that relief can come in multiple ways: lower back pain may be helped by placing the Miracle ball under your neck, or a bad knee might be helped by hip work. It's a revolutionary program of relief, from head to toe.
