The GRID Vibe Plus foam roller is one of the two TriggerPoint foam rollers with vibration function. It has different Distrodensity zones and a three-dimensional surface: low and flat like the palm, tubular like the fingers, and high & firm like the fingertips, helping to release tight muscles, knots, kinks, improving flexibility and mobility. The patented GRID pattern is designed to channel blood and oxygen while rolling, improving circulation for muscles’ fast recovery. The four vibration frequencies help to induce muscles relaxation, minimizing pains for muscles’ fast recovery in a comfortable setting. The small diameter (9 cm) provides less surface enabling targeted pain relief to deep layers of muscles tissues. GRID Vibe comes with an AC charging cord, a rechargeable battery that holds up to 2 hours of power in cordless mode.
