A standup exercise apparatus simulates running, jogging and climbing with arm exercise. Foot pedals move with smooth elliptical motion resulting from an orbital drive mechanism. An orbital link drives the foot support member with smooth orbital motion without the characteristic turnaround jerk associated with reciprocating member elliptical drives. Leg joint impact is controlled to be very low as to allow extended exercise without joint soreness. Adjustment is provided to change the pedal motion during operation. Arm exercise is coordinated with motion of the feet.
