    Abstract: A leg exercise apparatus having a supporting frame, a leg disposition assembly and a connecting panel. The supporting frame is pivotably connected to the leg disposition assembly, and an upper portion of the connecting panel is pivotably connected to the leg disposition assembly on its backside. A positioning bar passes through a lower portion of the connecting panel and is disposed in positioning grooves located on both arms of the supporting frame to secure the connecting panel. An end opening is located at an end of the supporting frame and connects to two tunnel grooves at both arms so the positioning bar can be pushed out through the tunnel grooves and end opening, which leads the leg disposition assembly to collapse into the supporting frame to form a compact and portable leg exercise apparatus.
