Claim:
1. A treadmill, comprising: an inclining and declining treadbase with an endless belt movably mounted to a first roller and a second roller; a motor adapted to turn the endless belt; a flywheel coupled to the motor, a rotational speed of flywheel being directly related to a speed of the endless belt; a current monitor adapted to monitor a level of current, anywhere along a range of levels, drawn to operate the motor; and a magnetic braking system arranged to prevent the endless belt from rotating at a speed that is faster than a speed selected at a console by a user, the magnetic braking system adapted to increase a magnetic resistance force on the motor in response at least in part to the current monitor detecting a decreased level of current being drawn by the motor, the magnetic braking system adapted to decrease a magnetic resistance force on the motor in response at least in part to the current monitor detecting an increased level of current being drawn by the motor.
