Abstract: Apparatus for training athletes, especially football lineman, includes a frame having a pair of guide rails extending between front and rear upright posts. The guide rails are arranged parallel to each other and have generally horizontal sections and inclined sections. The training apparatus also includes a weight assembly supported by the frame for movement on the guide rails. In using the training apparatus, an athlete moves upwardly and forwardly from a crouched position between the front upright posts of the frame and pushes the weight assembly along the horizontal sections of the guide rails and then up the inclined sections of the guide rails. The training apparatus is particularly effective in developing and strengthening the upper body muscles of athletes.
