Therabody's intelligent percussive therapy devices are scientifically calibrated and have an amplitude of 16 mm to penetrate deep into the muscles and increase blood flow. This promotes the supply of oxygen and the removal of harmful substances and improves the health and function of the muscles. The Theragun devices penetrate 60% deeper into the muscle than a conventional massage device - more precisely, up to 40 times per second - this results in a greater therapeutic effect on the body.
