Moreover, it is coupled with a movable handle at top thereof and a connecting rod at bottom thereof. The other end of the connecting rod is pivotably connected to the front assembly of the stepper. Accordingly, the pull rod, the connecting rod and the front assembly are coupled with one another. A position-limiting bar is inserted through the front end extending from the outer side of the upright rods.
