ABSTRACT:
An exercise machine comprising an elongate slide platform with a mount slidingly secured thereon, a footrest rotatably secured to the top of the mount, a base bar with one end thereof secured to the slide platform under the central portion thereof, a vertical post with the lower end thereof secured to the opposite end of the base bar, a pair of foldable pedal bars pivotably secured to respective lateral sides of the vertical post near the lower end thereof, and a pair of handles extending from respective lateral sides of the vertical post near the upper end thereof. The mount and the pedal bars are connected with resistance elements that resist the respective sliding and pivoting motions thereof. Resistance elements also resist the rotational motion of the footrest. Whereby, with hands gripping the handle bars and feet resting on the footrest a user can exercise various parts of his or her body by sliding the footrest to and fro along the platform or rotating the footrest in opposite directions about the mount, or with feet on the pedals, by pedaling up and down in stairclimbing fashion.
