Abstract
A tug of war machine is described which includes a belt loop which is pulled in a generally horizontal direction. The resistance placed on the loop can be selected to either provide a static pull or a hand-over-hand tug of war-type pulling exercise. Additionally, a treadmill may be used in conjunction with the tug of war loop cord to provide simultaneous exercise for the legs and the back. A monitor displays the performance of the user and compares this performance with the effort relative to a predetermined standard of reference.
