Abstract: A golf swing elbow angle control device for various types of golf shots, e.g. ninety degrees for long wood drives, and lesser angles for iron drives and chip shots. The device is readily adjustable, providing easy and rapid changes in its elbow angle control function, and customized fiducial settings of the device for various types of shots are readily established for the players having different forearm and elbow sizes and shapes. The device also functions as a convenient anchor for an elastic belt extending around the opposite upper arm of the player, keeping the arms together to provide a simple and easy way to prevent the player's elbows from extending away from the body, which is detrimental to good golf swing form.

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.
