Abstract: A golf swing training device includes an upper pivot member mounted on a support member disposed on a base frame, a lower pivot member disposed on a bottom frame portion of the base frame, and a swing path guide loop defining a swing plane and attached to the upper and lower pivot members such that said swing path guide loop is incapable of pivoting about an axis passing through said upper and lower pivot portions during the backswing, is capable of pivoting in one direction about the axis under the force of the club during the follow-through, and when pivoted during the follow-through, is capable of automatically returning its original positon. The golf swing training device thus constructed is able to assist the player in acquiring a correct swing achieved in the swing plane throughout the movement of a club including the backswing, downswing, impact and follow-through.
