Patent ID: 7381161

Claim:
An exercise treadmill of the type having an endless moveable surface looped around rollers or pulleys to form an upper run and a lower run, the movable surface being rotated when one of the rollers or pulleys is rotated, and an exercise surface for walking or running while exercising, the improvement comprising: a) a weight resistance means for providing a weight resistance for simulating the dragging or pulling of a load and wherein the endless movable surface moves in a direction simulating walking or running backwards; b) a pivot arm operatively connected to the weight resistance means, wherein pivoting the pivot arm actuates the weight resistance means so as to provide weight resistance for the simulating the dragging or pulling of a load; and c) a hand controller attached to the pivot arm for operating and controlling the exercise treadmill and the weight resistance means, whereby operation of the treadmill simulates the dragging or pulling of a load by a combination of the actuation of the weight resistance means to simulate the load and the walking or running backwards to provide the dragging or pulling action.
