Abstract
The present invention is an improved exercise machine for simulating stair climbing, particularly adapted for in-home use. The device includes a generally upright frame with a base. Right and left foot pedals are pivotally mounted to the base on either side of the upstanding portion of the frame and a handlebar is provided adjacent the upper end of the frame. The foot pedals are linked to a mechanical resistance element, namely a flywheel. The linkage includes a strap connecting each pedal to a single drive shaft, in turn connected by a belt transmission to the flywheel. A resistance adjustment feature is included in the invention.
