The Crotch Hook is the most diabolical of all the strap and brace devices designed to keep the head down during the swing. It consists of a headband with an elastic cord attached to a giant seven-inch fishhook which, of course, is fitted into the crotch of one’s trousers. Lift your head up too high during your swing and, well, you get the idea. Pavlov would’ve been proud.
