The M2 massage gun sends vibrations at varying speeds to relieve muscle tension. Lightweight (less than 1 kg) and cordless, it has a battery life of 3 hours. This device is designed to reduce the knots between the muscles and the fascia (a membrane covering the muscles, tendons and internal organs). It helps to relieve muscle fatigue and prevent muscle soreness. The massage gun works by using percussion therapy, the principle of which is to set a part of the body in vibration through the targeted muscles. It is perceived by the central nervous system as a series of micro-stretches to relieve pain, recover better after a sports session or simply to experience a feeling of well-being.
