Abstract
Abstract An exercising device comprising a computer associated with a plurality of actuating arms pivotally mounted on a chair frame, movement of each actuating arm being resisted by a double acting hydraulic cylinder. Position and pressure sensors associated with each of the hydraulic cylinders, and each of the actuating arms deliver signals through the microprocessor of a computer for indicating power or work exerted by the user for moving each actuating arm. A selector valve is connected to each double acting cylinder and is connected to a control valve to permit independent adjustment of the resistance to movement of the piston of a selected cylinder in opposite directions. The cylinders which are not selected on the selector valve are locked to prevent movement of the actuating arm associated therewith.
