Abstract: A running/walking machine, or treadmill, is disclosed which has an automatically controlled speed-varying electric motor and an automatically controlled elevation-varying electric motor. The commands are entered in a display panel having a microprocessor which communicates with the motor controlling circuitry. The display panel has feedback information in a pictorial display, controlled by the microprocessor, in which an oval track simulating a running track displays both the current position of the user in moving around the track and the percentage of completion of a pre-established goal. The track has a multiplicity of segments, each represented by an LED, and each constituting a given fraction of the distance represented by the complete track. A lighted LED, which changes as the user progresses, indicates the current position of the user; and a string of LEDs behind the LED indicates the portion of the total program which has been completed.
