Claim 20:
21. An auto lock system for a manual treadmill, the manual treadmill including a tread that rotates on front wheels supported on a front axle and rear wheels supported on a rear axle, the auto lock system comprising:
a locking mechanism comprising:
a movable arm having a distal end facing one of the front axle or the rear axle;
a locking device at the distal end of the movable arm,
a first member extending from the distal end of the movable arm and having a first surface carrying a first magnet and a first distal surface configured to engage the one of the front axle or the rear axle; and
a second member extending from the distal end of the movable arm and having a second surface carrying a second magnet a second distal surface configured to engage the one of the front axle or the rear axle, the first surface facing the second surface to form a channel; and

an actuator configured to move the movable arm;

a flange surrounding the one of the front axle or the rear axle and aligned with the channel;
a controller; and
a sensor in communication with the controller and configured to detect a user on the manual treadmill, wherein the controller is configured to:
in response to the sensor detecting no user on the manual treadmill, actuate the actuator to move the movable arm such that the flange is received in the channel, the first magnet and the second magnet slowing rotation of the one of the front axle or the rear axle via magnetic force on the flange; and
when the rotation of the one of the first axle or the second axle slows to a threshold amount, further actuate the actuator to move the movable arm so that the first distal surface and the second distal surface engage the one of the front axle or the rear axle.
