ABSTRACT:
An exercise device for use at home or in a gym by which a user can simulate climbing a ladder. First and second carriage tubes are slidable axially and reciprocally over respective first and second carriage guide rails that extend in spaced, parallel alignment between top and bottom frame members. The first and second carriage rails are interlinked by first and second drive cables and a series of cable pulleys so that the carriage rails move in opposite directions relative to one another in response to successive pushing and pulling forces applied by the user to hand grips and foot pedals connected to each of the carriage tubes. A hydraulic control system is provided to permit the user to selectively adjust the minimum force which must be applied to the hand grips and/or the foot pedals to cause the carriage tubes to slide along the guide rails. The hydraulic control system includes a piston that is connected to and movable with one of the carriage tubes and a hydraulic fluid valve that controls the rate at which the piston can be moved.
