Abstract
Abstract A golf swing training device for limiting movement of a golfer's following forearm with respect to the following upper arm during a backswing includes a base portion which is positionable on the bicep of a golfer's upper arm adjacent to the elbow and a fastener for securing the device at a fixed position. A wall extends upwardly from the front end of the base portion to form a substantially L-shaped configuration. The wall contacts and prevents further bending of the golfer's forearm at the top of the backswing so that the angle formed between the forearm and the upper arm is approximately 90 degrees at this position.
