Discover an efficient way to massage your own back and neck with the TRNR Dual Sphere. The spine-cradling design prevents contact with spinal discs and delivers a bilateral deep-tissue massage of the muscles surrounding the vertebral column. The Dual Sphere can also be used on your calves, hamstrings, quadriceps, hips, and glutes. The unique textured surface provides enhanced traction, while the high-density EVA foam retains its shape post-compression.
