NOVELTY - The apparatus has a motor (14) including a rotor connected to an exercise apparatus e.g. running belt, of an exercise machine e.g. exercise bike, through a transmission device. A circuitry has a resistor i.e. variable resistor, and includes opposite ends that are electrically connected to the motor. The rotor of the motor is turned through the transmission device to generate induced current flowing through the circuitry when the exercise apparatus of the exercise machine is moved. The circuitry flows the induced current back to the motor to drive the rotor turning reversely.    USE - Loading apparatus for an exercise machine that is utilized by a user such as spine injury patient and diabetics, in gym and home for body building or weight loss. Uses include but are not limited to a treadmill, exercise bike, stepper and an elliptical trainer.    ADVANTAGE - The apparatus can provide a brake for the exercise apparatus of the exercise machine without any power input. The apparatus eliminates a need of additional power to generate loading. The resistance of the circuitry is infinity when a switch is turned to OFF, so that no induced current is flowed back to the motor through the circuitry, thus enabling the apparatus to be inoperative, hence facilitating the apparatus to provide the user a constant loading when the switch is turned to ON. The apparatus makes the induced current small when the resistor in the circuitry has a great resistance to make the potential difference between electrodes greater, so that the power of driving the rotor turning reversely is small, thus enabling the apparatus to provide a small loading to user while using exercise machine. The induced current flows back to the motor through the circuitry when the resistor of the circuitry has a small resistance, so that the power of driving the rotor turning reversely is better, thus enabling the apparatus to provide the user a great loading.
