Have you ever had a massage therapist chop away at your quads or pecs like John Wick going to town on some poor sap’s face? If so, you know it hurts, but in a good way. Especially if you’re a longtime lifter whose muscles are riddled with knotty trigger points associated with months and years of steady effort in the gym.

A few years back some techy types posed the question: what if you could pound a muscle yourself way faster, way harder and with little to no effort? Enter the massage gun, a handheld, rechargeable device that can thump away, up to 2500 times a minute, for as long as you can endure it.
