ABSTRACT:
A standup exercise apparatus simulates walking and jogging with arm exercise. Foot pedals move with heel and toe curves inclined in opposing directions. The pedals incline with the toe above the heel during the latter portion of forward movement of the foot while the heel inclines above the toe during the latter portion of rearward movement of the foot. Foot pedals move with smooth elliptical motion resulting from a linkage mechanism guiding one foot support member pivot and a rocker link to support the other foot support member pivot. The pedal is is pivoted to one end of the foot support member and articulates the pedal angle separately from the foot support member. 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.
