A treadmill includes a treadmill that comprises a base and a belt frame has a first end pivotably connected to the base and a second end of the belt frame is a free end. An endless belt is mounted to the belt frame. A support frame is pivotably connected to the base and is driven by a mechanism so that the support frame can be pivoted relative to the base to lift the first end of the belt frame to adjust the inclination of the belt frame. The support frame may support and lift the whole belt frame to fold the belt frame upright.
