ABSTRACT:
A standup exercise apparatus simulates speed walking and climbing with elliptical arm exercise. Two pair of foot pedals move with an up and down treadle movement. Operation begins with a warm-up stretching movement on a first pair of pedals followed by a more aggressive climbing movement on a second set of pedals. 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 to simulate rowing in one direction of crank rotation and ski pole motion in the other direction of crank rotation. Two operators can exercise on the apparatus at the same time.
