Abstract
Disclosed is an arm and leg compound exercise machine using a pair of crank units and a lifting device to adjust leg motion track and exercise tension and allow users to timely adjust the exercise strength for leg exercise. When a foot pedal installed onto the arm and leg compound exercise machine is operated, the motion track produced by the foot pedal is an elliptic motion path, and the elliptic motion track is flat and gentle at the top and arc shaped at the bottom, so that the motion track produced by the users' stepping motion is ergonomic for preventing sports injuries.
