ABSTRACT:
A leg exercise equipment is disclosed, which includes a base plate, a supporting frame foldably mounted to the base plate, and a crank mechanism. The crank mechanism includes a swinging arm, of which one end is connected with a hydraulic cylinder through a shaft. The other end of the hydraulic cylinder is connected with a connecting pin which is fixedly fastened to the supporting frame. A leg holder is mounted on one end of the swinging arm. When the user's leg exerts force to the leg holder, the force will be transmitted to the hydraulic cylinder to drive the same to move back and forth so as to cause the leg muscle and hip muscle to be exercised evenly.
