ABSTRACT:
An exercise machine is provided that includes two stepping platforms with pedal arms pivotally interconnected to a frame. The pedal arms are moved in a substantially vertical direction by the application of forces during the stepping motion by the user. The applied forces are resisted by fluidic cylinders physically connected such that the fluid can be forced through a resistance valve between the two cylinders, enabling an adjustment to the resistance to the movement of the pedal arms. A pair of cables attached to the pedal arms and the cylinder piston rods interconnects the pedal arm motion via fluid, passing through a resistance valve, between the connected cylinders. Preferably, the pair of lifter cables are adjustable or replaceable by another pair of lifter cables having different lengths.
