ABSTRACT:
A ladder-climbing exercise device (10) includes an inclined flight (13) along which a plurality of rungs (29) are presented in an endless manner. The marginal ends of the rungs are mounted on endless chains which are supported by a frame. The chains are coupled to a fan (43) having a squirrel cage-like rotor. The position of an operator (P) relative to the flight changes the size of a fan aperture (45) to vary the resistance afforded by the device to the climbing motion.
