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.
