Designed with a unique textured pattern, the RUSH Roller effectively shears muscle tissues to promote range of motion and glide. Shearing works to improve mobility by kneading muscles in multiple directions. Built with firm, high ridges and a hollow core, the RUSH delivers tiered muscular compression that improves tissue hydration and elasticity. Featuring a patented hollow core design, the RUSH retains shape after frequent and repeated use. The easy-to-clean and sweat-resistant EVA foam surface are ideal for post-workout recovery sessions, while the textured pattern stimulates pre-workout mobility. As a specialty Level 3 foam roller for direct compression, the RUSH delivers an unsurpassed and targeted total-body massage.
