Abstract: A motorless exercise treadmill has a flywheel of 7 to 10 inches radius, weighing 40 to 60 pounds. The flywheel provides a fluid motion for the belt when the brake system is engaged and smooth transition through increasing or decreasing speeds. Inclination of the treadmill is fixed at 9 to 20 degrees, which accommodates the large size of the flywheel. Handle and other attachments of different designs are provided so the user can exercise in various positions with various resistance levels for developing specific leg, core, arm and other muscles, not normally achievable on a treadmill.
