Abstract: A golf wrist training apparatus is attachable to the arm of the golfer-in-training, and controls the range of wrist movement during each of the various phases of a golf swing. The apparatus includes a hand-attachment member and a forearm-attachment member. The apparatus restricts enables the wrists to move freely in the lateral plane of motion, and restricts wrist movement within the forward/backward plane of motion. The backswing allowable range of motion is greater than the downswing allowable range of motion. The apparatus also includes a release mechanism which enables the apparatus to be easily reset prior to each use.
