Massage guns provide percussive or vibration therapy, which is a type of massage that applies rapid bursts of pressure to muscle tissue. Percussive therapy helps increase blood flow to a hyper-targeted area, which can then help reduce inflammation and muscle tension, as well as begin to break up knots that may have formed in the muscle tissue due to stress or following a particularly intense workout. Massage guns do not completely eliminate muscle soreness, but they can help alleviate it.
