Massage guns like this popular one from Theragun use percussive therapy to ease tension, loosen muscles, and relieve pain or soreness by getting deep into the muscles, like a deep tissue massage. It targets localized spots on your body, making it useful for knots in your back, shoulders, legs, and anywhere else you can think of. This massager is ideal for people with extremely tight muscles, since it’s designed to reach 60 percent deeper than other similar massage guns, according to Therabody. To buy: $198 (was $299); therabody.com The massage gun has an ergonomic grip—the brand’s patented Theragun Triangle handle design—that you can easily hold while using it, without straining your arms. Plus, you can even use it while watching TV because it’s designed with QuietForce Technology to make it extra quiet. According to the brand, it’s quieter than an electric toothbrush. Five built-in speeds, adjustable speeds, and four different attachments (dampener, standard ball, thumb, and cone) allow you to choose the best options for your muscle issues, so you can totally customize your massage.
