Our Chirp Wheel delivers just the right amount of pressure to dig deep into tight muscles and sore backs. Use the wheel to comfortably and effectively massage those tense and tight areas up and down your back. Depending on the size of the foam roller used, you can stretch and massage your legs, IT band, and glutes too. INNOVATIVE & FUNCTIONAL DESIGN: Chirp Wheel+ is designed with trigger points in mind to break up tight muscle fibers and hard-to-reach parts in your back instead of putting undue pressure on your spine, so you can focus on deeper stretches without worries. Our 12" wheel back stretcher gives gentle pressure massage and specifically targets the area in contact with the muscles at any given point providing a satisfying amount of pressure in general.
