ABSTRACT:
Equipment for exercising the muscles of a user includes a horizontally extending main frame and bench, an elevator leg supporting an elevator carriage for vertical movement with respect thereto situated at one end of the bench, an endless chain extending from the top to the bottom of the elevator leg and means to attach the elevator carriage to the main chain at appropriate heights. Actuating arms can be temporarily fixedly mounted to the elevator carriage so that a user can make repetitive movement in upward or downward direction on those arms. A chain sprocket driven by the endless drive chain drives a pinion which drives a rack/piston rod forming part of a piston/cylinder positive displacement linear pump. A path is provided between the opposite ends of the pump, and means is provided in the path to restrict the flow of fluid thus to provide resistance to repetitive movements of the user on the actuating arms in one direction.
