Abstract
Apparatus that controls the cycle rate of various incline or stair-climbing simulation exercise machines in a nonlinear fashion so that the downward step movement is slowed appropriately during portions of its travel to facilitate cyclic 'step-up' i.e., raising of the user's center of gravity; this slowing occurring during the uppermost portion of the step's descent (and/or the lowermost portion in some cases) while the rest of the descent is made at higher speed; including a pair of hydraulic cylinders serving as a means of coupling the steps together and dissipating the energy transmitted by the user, the flow of fluid between the cylinders being controlled during the step descent by variable orifices controlled by cams or a cam/switch/solenoid system.
