An exercise apparatus includes a base having a support stand upstanding therefrom. A pair of spaced apart foot rails each have a first end and opposing second end. The second end of each foot rail rests on the base of the frame. A pair of stroke rails each have a first end and an opposing second end. The first end of each stroke rail is slidably attached to the support stand of the frame while the second end of each stroke rail is hingedly attached to a corresponding foot rail. An axle of a crank is rotatably mounted to the support stand. A pair of crank arms each orthogonally project from the corresponding ends of the axle in opposing directions. Each remote end of the crank arm is rotatably mounted to a corresponding stroke rail between the ends thereof.
