Abstract: A resistance training device which includes a boom which may be connected at a variety of positions to a frame. The boom is provided with a curvilinear track in which a runner attached to handle is disposed. The runner is connected to a set of weights via a cable and pulley arrangement. In use, the handle and associated assembly is moved down the track against the resistance of the weights. The shape of the track is arranged to simulate the action of a limb during a sporting movement, for example the movement of the user's arm when taking golf swing, so that the apparatus exercises the user's muscles in precisely the way that is required for maximum benefit for the sporting action which corresponds to the shape of the track.
