Developed by a doctor of physical therapy, this is the rocking board that targets trigger points to relieve back, neck, and shoulder pain while aligning the spine. Users leverage their own body weight by lying on the board’s raised nodes to apply deep pressure that eases muscle tension, increases blood circulation, and relieves pain. Rocking side to side provides an extra release of muscle tightness. Its unique contoured shape promotes a neutral spine position in which all three curves are in proper alignment. Can also be used as a backrest to help you maintain proper posture. Includes an exercise program with more than 30 exercises and stretches. Recommended for one session a day up to 15 minutes. For users 5'0"-6'6" up to 300 lbs. 25 1/2" L x 71/2" W x 3 3/4" D. (2 1/4 lbs.)
