ABSTRACT:
An exercise apparatus for simulating a stepping motion, wherein the horizontal components of the stepping motion may be either parallel, or opposed. The apparatus includes a first and second stepper mechanism connected by a central pivot. Each stepper mechanism includes a mechanism for yieldably resisting downward motion of a foot platform. The central pivot allows the stepper mechanisms may be aligned in a parallel orientation, wherein the horizontal component of motion of each foot platform is parallel. Alternatively, the central pivot permits orientation of the stepper mechanisms in an opposed or end-to-end relation, wherein the horizontal component of motion of each foot platform is colinear and opposed.
