They don’t call it Mini for no reason. The Theragun Mini is currently the smallest “massage gun” in the Theragun line. At roughly 5 inches by 4 inches by 1.5 inches, it’s nearly the size of your palm and can fit in your hand (or really anywhere) very easily. At under 2 pounds, it will hardly be noticed in your purse, backpack, or gym bag. It’s unique shape allows it to stand out from other mini massage guns. It is a rounded triangle shape that has concave sides. The massage head comes out of one corner of the triangle of the device.
