A modified fitness equipment of three-dimensional sway structure. The basement is provided with a pedal while a crosswise movable pipe is mounted at the bottom of the pedal. And, a dragging member is installed to provide a preset resistance to pedal during treading movement. Also, one end of the movable pipe is connected to the exterior of a shaft lever at one side of a vertical pivotal pipe over the basement. Thus, a movable end with horizontal spin can take shape at the other end of the movable pipe while a vertical swinging arm shall be installed convexly at the bottom of the movable end. Besides, the bottom of the swinging arm shall be connected to the exterior of a coupled bar via a first pin joint. The movable end of the movable pipe can horizontally sway during the treading movement, thereby generating more flexible three-dimensional sway during application.
