Theragun Elite Percussive Therapy Device When I'm stressed, I get knots in my back, as so many of us do. Instead of living in pain, I use the Theragun Elite Percussive Therapy Device ($399). It's intense, but it really does work like you've just gotten a deep tissue massage, and since I'm not going to get a massage, this is brilliant.
