The Trigger Point Charge Vibe Roller offers vibration and foam rolling in a convenient, portable package. It maximizes your recovery with minimal effort by using 3 built-in vibration frequencies in order to relax your muscles. High and low ridges let you alternate between stretching and squeezing the muscles, while the silicone grips your skin to improve blood circulation. A unique design allows you to target specific muscle groups like your IT Band, quads, calves or any other muscle group that is troubling you.
