LIFE FIT Twist Roll Fit009 (Blue) Electric Foam Roller for Myofascial Release, Stretching, and Myofascial Care

Vibrations loosen muscles, making them easier to move. Furthermore, adding a twist can thoroughly stretch contracted muscles and the range of motion of joints. The twist roll improves the movement efficiency of a loosened body, and by adding a twist, you can thoroughly stretch areas that are difficult to stretch with a regular stretch roll. The rechargeable battery also saves money (max charging time: 2 hours / usage time: 1 hour)
