The exercise apparatus also includes a seat unit movable along the track between a first position adjacent to the first terminal end and a second position located far apart from the first terminal end. A distance difference relative to the seat unit is produced by a wheel pedal unit movable along the track between a first pedaling position adjacent to the second terminal end and located horizontally far apart from the seat unit, and a second pedaling position located far from the second terminal end and horizontally adjacent to the seat unit. Thus, changing the position of the wheel pedal unit and the position of the seat unit can change the distance difference between the seat unit and the wheel pedal unit in both the vertical and horizontal directions. This enables a user to selectively perform different exercise modes in either a normal sitting posture or a recumbent sitting posture. ## Claims ### Claim 1 An exercise apparatus, comprising: a base comprising a first terminal end and a second terminal end located at different elevations and spaced from each other at a predetermined distance, and a track extending between said first and second terminal ends;
