Works –> back; shoulders
Lie face up, hands palms up next to hips. Push down on the CoreSliders. Move them up, pausing for two seconds at each clock position (7:00/5:00, 8:00/4:00) until both CoreSliders reach 12:00. Pause; slide back down to the start. Next, push down and maintain that pressure as you circle up to 12:00 and then as you return to the start.
