ABSTRACT:
An exercise treadmill machine is provided in which an optical sensor monitors the position of a user on the treadmill and automatically varies the speed of the treadmill to keep the user near a predetermined position on the treadmill's endless belt. The optical sensor preferably includes an infrared (IR) emitter and an IR detector which are located in or near the treadmill control panel that also houses a preprogrammed microprocessor. The microprocessor controls the speed of the belt as required to adjust for variations in the position of the user.
