ABSTRACT:
This invention is an improvement in stair exercising equipment which recognizes the importance of training muscle groups, tendons, and ligaments for walking downhill on steps or on an incline. Accordingly, it provides powered means for a moveable staircase, for an incline, or for reciprocating pedals to rise, thereby allowing a person to walk downhill.
