The swinging mechanisms are symmetrically disposed on two sides of the base frame and are independent of each other. The base frame comprises a pivoting bracket located at a top thereof. Each of the swinging mechanisms comprises a swing rod, a stepping rod, and a telescopic elastic member. The swing rod and the telescopic elastic member are respectively pivoted to the pivoting bracket with tops thereof and are respectively pivoted to the stepping rods with bottoms thereof. The swing rod and the telescopic elastic member are parallel to each other with one in the front and another one in the rear. The telescopic elastic member retracts and returns after being stretched. The stepping rod has a stepping portion, which is further away from the pivoted swing rod than the telescopic elastic member. The stepping rod may be swaying back and forth along with the swinging of the pivoted swing rod and may drive the telescopic elastic member to stretch while the stepping portion is swinging downward by a press-down force. The telescopic elastic member retracts when the press-down force vanishes, and drives the stepping rod to swing upward and return, so as to provide various fitness modes.
