CanDo® Back Stretcher is designed to mimic the natural curve of the spine. This design is used to correct posture and stretch your back muscles. Simply recline on the CanDo® Back Stretcher so that the spine aligns with the indent in the middle of the back stretcher. Lie on the back stretcher for five-minute intervals as it supports the back and muscles. Regular use of the CanDo® Back Stretcher can improve posture and relieve any discomforts caused by poor posture, including: muscle spasms, headaches, and muscle tension.
