A muscle relaxation gun, also known as a percussion or massage gun, is a handheld device designed to deliver rapid, concentrated pulses of pressure into muscle tissue to relieve soreness, stiffness, and tension. By using powerful percussive therapy, it helps increase blood flow, reduce lactic acid buildup, and speed up recovery after exercise or physical activity. With adjustable speed settings and interchangeable massage heads, muscle relaxation guns target specific muscle groups for deep tissue relief, making them popular among athletes, fitness enthusiasts, and anyone seeking effective, on-demand muscle relaxation.
