Abstract: This invention consists of a rotatable pulley or reel attached to an inverted U-shaped mounting bracket, with a flexible cord attached to and wound around the pulley or reel, whose rotation is retarded or resisted by the strong force or tension of a coiled spring or elastic cord, with a handle of wood or other material attached to the other end of the flexible cord so that when the inverted U-shaped mounting bracket is hooked or fitted in place over the horizontal top of a door or other appropriate support the handle may be pulled downward and away from the pulley or reel in a simulated golf stroke downswing to unwind the flexible cord as it rotates the pulley or reel against the strong force or tension of the retarding or resisting coiled spring or elastic cord that is connected to the pulley or reel.

Abstract: This invention consists of a flexible cord attached to and wound around a strong spring-loaded, spring-retarded, spring resisted or spring-counterbalanced pulley mounted upon a wall or other stationary vertical support surface, with a handle of wood or other material attached to the other end of the flexible cord so that when the handle is pulled in a downward movement away from the strong spring-loaded pulley, in a simulated golf stroke downswing, the cord rotates the pulley against the strong force or tension of the counter-balancing spring that is connected to the pulley. By making many continuous and repeated downswings with this apparatus all of the muscles used in driving a golf ball are strained and strengthened, enabling the golfer to hit the golf ball farther when playing on a golf course.
