While a bit pricey, the Therabody Theragun Elite ($399) is a worthwhile investment. Its ergonomic handle allows users to hold the massage gun a multitude of ways, making it easier to treat those harder-to-reach muscles. Additionally, the massage gun promises 90 interrupted minutes of treatment and up to 40 pounds of force, and thanks to its QX65 Motor's advanced QuietForce Technology, it's quieter than an electric toothbrush.
