Abstract: A treadmill includes a frame; a running belt configured to rotate relative to the frame; and a motor coupled to the running belt. The motor is operable in a plurality of user controlled operating modes. In a first operating mode, a holding torque of the motor is disabled to allow the running belt to substantially freely rotate so that a user of the treadmill provides a force of rotation to the running belt. In a second operating mode, the motor is adapted to resist rotation of the running belt.
