A yoga wheel is designed to support users during stretches that open the back, shoulders, and chest. It's also a great tool to realign the spine. Use it to increase the challenge during yoga routines as the core is engaged to improve balance and stability. The wheel's foam padding increases support and comfort during use. Lightweight, portable design makes it easy to bring it on the go, yet it is tough enough to support over 400 lb. 5"W x 13" outer dia (11½" inner dia); 3 lb.
