The Pettibon System 6-Way Neck Stretch Strap is great for people with stiff or sore necks who want to increase flexibility and range of motion. Our strap helps stretch the spine in 6 directions, (Anterior Right/Left, Lateral Right/Left, and Posterior Right/Left) through resistance and dynamic exercises. Regular use of the 6-Way Neck Stretch Strap increases flexibility which can expand or preserve the range of motion and relieves pain. Stretch chronic splinted postural muscles so normal muscle function and muscle memory can be re-established. Using the strap with the Pettibon 6-Way instructions included with your 6-Way Neck Stretch Strap is the best way to get maximized results.
