Abstract: A motor-less leg-powered curved treadmill produced that allows people to walk, jog, run, and sprint without making any adjustments to the treadmill other than shifting the user's center of gravity forward and backwards. A closed loop treadmill belt is formed with a low friction running surface of transverse wooden, plastic or rubber slats attached to each other in a resilient fashion. Since an essential feature of treadmill is the concave shape of the running surface of belt in its respective upper portion, curved and linear arrays of bearings are used to insure that this shape is maintained during actual use. These bearings prevent the lower portion of the treadmill belt from drooping down (i.e.—it must be held taut), to prevent the top portion to be pulled taut into a flat shape between the front and rear pulley rollers.

Abstract: A portable, electronic device having wireless location or positioning technology used to test and improve the physical fitness of a person is provided. The device includes a memory, an operating program, a user interface, a display and a location signal receiver adapted to receive location signals from a plurality of sources external to the fitness training device. A command and control circuit is coupled to the memory, the user interface, the display and the location signal receiver. The control circuit executes the program and generates control signals based upon the user entered data and the location signals from the receiver. The device tracks the distance traveled by the device throughout the performance of an exercise routine based upon the location signals and thereby determines the fitness level of the person. The program then determines a plurality of timed exercise regimens based upon the calculated fitness level.

Abstract: A system and method are provided for improving the physical fitness of a person wherein the person performs at least one walking or running exercise routine at substantially that person's maximum performance level for a period between 1 minute and 10 minutes. Based on that maximum performance level, the method and system determine a variety of timed walking or running exercise regimens, each regimen including at least one routine to be performed by the person on a regular basis and wherein no single routine exceeds 10 minutes in duration. The person then selects and performs one or more of the walking or running regimens such that the person completes at least 10 minutes of exercise in a training session. The routines vary in duration from 1 to 10 minutes and in repetition from 10 to 1 repetitions. Numerous embodiments of the system are included such as a portable device.
