The Zon 18" Foam Roller can be used to gently massage, stretch, and relax muscles by releasing built-up tension, loosening stiffness, and elongating and aligning the skeletal system. It can also be used to enhance balance, flexibility, and core function, as well as back stabilization and strengthening routines. For therapy and rehabilitation, the foam roller can be used to increase circulation, expand range of motion, and restore soft tissue through different massage and body-rolling techniques.
