Abstract

The present invention is an oval track stepper, which has resolved the disadvantage of a typical oval track stepper by having rear ends of left and right stepping rods linked to left and right sides of a freewheel set and the enclosure, leading to excessive spacing against stepping comfort. The oval track stepper includes a main frame, a head frame, left and right stepping rods, left and right vertical swing rods, a freewheel set and damping device. The freewheel set and damping device are mounted externally at left and right stepping rods. An obstruction-free and closer space between left and right stepping rods delivers an optimum stepping distance for the users, thus improving comfort and practicability.
