ABSTRACT:
A standup compact exercise apparatus simulates walking and jogging with arm exercise. Foot pedals move with a back and forth movement following an elongate curve path that has a curve length that is longer than twice the crank length. The stride length of the foot pedals is adjustable to accommodate both long and short leg users. Foot pedals move with smooth elliptical motion resulting from a linkage mechanism having 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. Arm exercise is coordinated with motion of the feet.
