Motorless treadmill stepper exercise device

摘要

An exercise device can include a frame, first and second treadle assemblies, and a one-way drive system. Each treadle assembly can include a deck and tread belt rotatably coupled to the deck. The treadle assemblies can be pivotably mounted to the frame. Downward movement of the two treadle assemblies can cause the tread belts associated with the treadle assemblies to rotate relative to their decks.
