Abstract: A computer exercise system for requiring a user to exercise prior to being granted access to use a computer. The computer exercise system includes a computer having a processor, an exercise device and a scanner connected between the computer and exercise device. The sensor detects use of the exercise device and, upon detecting such use, transmits a signal to the processor. The processor prevents access to the computer until the signal indicating use of the exercise device is received from the scanner for a predetermined period of time. The computer further includes a monitor connected to the processor for displaying an image indicating a period of time for which the signal must be received by the processor from the scanner in order to be granted access to the computer. The processor includes a memory for storing account information for a plurality of individual users, each individual user being assigned an account and each account being assigned a unique user I.D. and password.
