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 running between front and rear pulley rollers 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, to insure that this shape is maintained during actual use. This prevents the lower portion of the treadmill belt from drooping down (i.e., it must be held taut), to prevent the concave top portion to be pulled taut into a flat shape between the front and rear pulley rollers.
