Abstract: The present invention provides a golf swing training device which allows the angular relationship of the leading and trailing forearms with respect to each other to change during the golf swing while substantially maintaining the distance between the forearms at the points at which the training device is attached to the forearms. The device comprises a first strap which attaches to the leading forearm below the elbow and above the wrist, a substantially rigid spacing member that is attached to the leading forearm strap by means of an articulating joint, and a second strap attached to the other end of the spacing member which attaches to the trailing forearm below the elbow and above the wrist. The spacing member preferably is adjustable in length to accommodate different distances between the forearms.
