Abstract
A novel treadmill has a practical hand-powered system to replace the electric motor for driving the tread belt. The hand-powered system includes fixed range movement of both handles, cranks coupling system for two handles, and a cyclic spring or magnetic energy storage and release system to help pass each handle's dead spot. The handles' pivotal and reciprocal movement can be smoothly and efficiently converted to tread belt movement.
