Two swing arms are respectively pivotally connected to a rear portion of the base due to a pivot structure that is mounted in a corresponding one of the two swing arms. Each swing arm has an endless strap sleeved thereon for user to step thereon. A drive shaft pivotally extends through the pivot structures for driving the straps and supporting the two swing arms. A motor is mounted on the base for driving the drive shaft. A restitution structure is mounted under a corresponding one of the two swing arms for providing a restitution force to the corresponding swing arm after being downward stepped.
