Abstract
A golf swing strength trainer has a shaft of length not greater than that of a standard golf club shaft. A golf grip is fixed to one end of the shaft. A golf club head is fixed to the other end of the shaft. A pair of substantially equal weights is fixed concentrically on the shaft, one on each end of the grip, the center of gravity of the weights taken together being located substantially at a lengthwise center of the grip. Preferably, the weights abut the opposite ends of the grip. In use, as the axis of the shaft comes into horizontal and vertical alignment, the horizontal distance of the weights from the center of gravity is maximized and minimized. This relationship seems to trigger rather than inhibit the transitional phases of the swing. Since the weights, regardless of their anglular position, are equally displaced from the center of the grip, they tend to enhance rather than inhibit flow and transition of primary movers in the proper swing plane. At the same time, the muscles are responding to the total weight of the trainer, which serves to increase strength, the primary goal of the strength trainer.
