Abstract: The present resistance exercising apparatus for strengthening a golf swing includes a golf club swingably connected to a telescoping shaft. The telescoping shaft in turn is axially connected to a wheel which is mounted in a frame transversely of the golf club. The wheel engages a set of four rollers which bring pressure to bear on the wheel to create resistance to rotation of the wheel. The rollers are mounted in half-moon housings and drawable to or away from the wheel to increase or decrease the resistance to rotation of the wheel. Accordingly, the resistance apparatus may be set for a quicker golf swing with little resistance or a slower golf swing with greater resistance.
