ABSTRACT:
A stepping exercise machine has hydraulic cylinders to resist downward movement of its pedals or treadles and a bias spring to urge the pedals or treadles to their upper position of travel. A plurality of receptacles such as holes or slots interconnect with a hook associated with one end of the hydraulic cylinders to in turn vary the resistance to movement of the pedals or treadles.
