A simulated stair climbing-type exercise apparatus is provided having a frame,
a resistance member, a transmission, a drive belt, a right pedal assembly, a left
pedal assembly and a track mounted to the frame to provide a user with a vertically
reciprocating exercise movement. The right pedal assembly, operating independently
of the left pedal assembly, oscillates between an upper position at rest and a
lower position under the weight of the user. The left pedal assembly, operating
independently of the right pedal assembly, oscillates between an upper position
at rest and a lower position under the weight of the user. The pedal assemblies
remain parallel to a support surface throughout their entire range of motion, as
the pedal assemblies travel from their upper position to their lower position on
the tracks which can be either linear or curved.
