Hey Bro, when you say buttocks you don't mean your cheeks right. Incase you do mean cheeks. A glute shot is more of a hip shot. Here's how I do it, put your hands on your waist, where your thumb is go 1-1 1/2" below that, that's the spot. Atlest that's where I tell my wife to put it, since she does all my glute shots.
