An exercise apparatus is provided that simulates jogging, running and climbing with elliptical pedal motion and arm exercise. The pedals are guided by extended foot supports that have one pedal pivot following an elongate curve path while the other pedal pivot follows a different curve path. In the preferred embodiment, the elongate curve path is provided by a four-bar linkage coupler point while a rocker link extension provides arm lever exercise. Pedal motion and arm exercise can be adjusted during operation of the exercise apparatus.
