An exercise device includes a pair of foot engaging links (30a, 30b). The rearward ends of the foot links are supported by a coupling system (100, 102 , 104, 110) for arcuate motion about a closed path of travel, and the forward ends of the foot links travel back and forth along a guide (36). The combination of thes e two foot link motions permits the users feet to travel along an elliptical path of travel. The inclination or elevation of the guide may be selectively altered to vary inc lination of the foot links which in turn changes the nature of the stepping motion exper ienced by the user. At flatter inclinations of the foot links, the stepping motion may resemble cross country skiing. At progressively greater angles of inclination of the foot links, the stepping motions may simulate walking, jogging, running and climbing. Al so, the coupling system may be adjustable to change the length of the closed path of travel of the rear ends of the foot links.
