Abstract: An exercising device which can train the user in a particular sport, while simultaneously strengthening the muscles used in that sport. Weights are connected via a cable and pulley mechanism to a slider which slides along a track having a selected length and curvature depending upon the sport of interest. The track is interchangeable thus allowing the device to be used for any number of different sports. A handle attached to the slider enables the sliding means to be pulled along the track by the user.
