An adjustable exercise apparatus of the present invention includes a vertically-oriented frame having an operable cable threaded therethrough connecting a pull bar to a plurality of weights. The cable is directed over pulleys so that a person pulling on the pull bar will lift the weights against the force of gravity. A pair of curved guide rails extend upwardly and forwardly from the forward end of the frame with the center of the arch of the guide rails located generally above the seat upon which the person will sit to operate the apparatus. A carriage is mounted on the guide rails and is designed to guide the cable from the weights to the pull bar. The carriage may be selectively positioned at a plurality of points along the guide rails from the forward upper end to the rearward lower end. A spring-actuated pin cooperable with a plurality of apertures in one of the guide rails to maintain the carriage in a predetermined position. Release of the pin from the aperture permits movement of the carriage along the guide rails.
