The 21-inch Ply-U-Flex Massage Stick is crafted from high-quality beechwood. It is specifically designed to eliminate fascia adhesions and knots in the muscle tissue, which can impede muscle movement and blood flow, resulting in longer recovery time and muscle pain. The smooth side of the stick is ideal for warm-up, while the double-beveled grooves assist in pulling on the skin and releasing adhesions in the fascia. The stick's curvature allows for access to different body curves, making it easier to use on other muscle groups. Incorporating this stick into your daily routine can help reduce recovery time, alleviate pain, and heal soft tissue damage.
