25W Mini Deep-Tissue Massage Gun - Black

Percussion massage in something that fits a gym bag rather than a suitcase. The 25 W motor is sized for calves, forearms and shoulders — the places you can reach yourself — rather than for a physiotherapist leaning on a back.

Interchangeable heads change the contact: a broad one for large muscle, a narrower one for working into a knot. It recharges rather than taking batteries, and at ten dollars it is the one to keep in the bag and use after a session instead of the good one at home that you forget.
