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
and having a set of rollers engaged with the track, 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 and having a set of rollers engaged with the track, 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.
