Using fascia gun after exercise, according to the principle of stimulating pain points, impact the muscles after exercise for a long time, thus helping to metabolize lactic acid and reduce muscle tension. For example, after doing push-ups, use a fascia gun to impact the position of pectoralis major and pectoralis minor for more than two minutes. Fascia gun uses its special high-speed motor to drive the "gun head", which produces high-frequency vibration to deep muscles, thus reducing local tissue tension, relieving pain and promoting blood circulation.
