Percussion plus kneading: get a high-impact percussion massage and a shiatsu-style kneading massage from one device. A key tool for post-workout recovery is to strike the muscle tissue but cannot knead. The Myo-Therapy also adds a shiatsu-style massage that moves tissue and muscles in a kneading motion to help increase blood flow and speed recovery.   Reach your back: if you have ever tried to give yourself a back massage, you know how difficult and awkward it can be to hold in place to dig into that aching spot. The handle extension and oscillation arc movement of the Myo-Therapy Massager allow effortless reach and relief up and down your entire back, from shoulders to lumbar area.  Maximum versatility and endurance: with 5 therapy disks and 4 speed settings, you are in control of a custom massage experience, whether to enhance athletic performance, to speed recovery of sore muscles, or to simply relax. Up to 150 minutes of usage time from a single charge plus a handy storage pouch make a versatile and effective muscle massage possible anytime, anywhere. The Myo-Therapy Oscillation Massager is your ultimate easy-to-use solution for recovery, relaxation, and relief. HM21
