ABSTRACT:
An exercise mechanism includes a pair of foot posts having a lower end pivotally coupled to a base. A seat post has a front end pivotally coupled to the base and has a shaft rotatably secured to the middle portion. An extension is extended from the shaft and rotated in concert with the shaft. A lever has a middle portion pivotally coupled to the base at an axle and has a rod secured in the rear end and slidably engaged beneath the seat post. A link pivotally couples the lever to the foot post. A bar is pivotally coupled between the extension and the rod for moving the rod relative to the shaft and for rotating the lever about the axle. A pair of handles have a lower portion secured to the shaft for rotating the shaft and the extension. The rear end of the seat post is moved upward and downward by the rod when the lever is rotated about the axle by the extension.
