AbstractAn exercise device (10) has foot supports (30, 32) on which a user stands for performing a stair stepping exercise alone, or a cross country skiing exercise alone, or simultaneously a stair stepping exercise and a cross country skiing exercise. Linkage support frames (26, 28) each have a first linkage (44) and a second linkage (36) pivotally connected to each other for maintaining foot supports (30, 32) in a horizontal plane. A fluid cylinder (52) provides a mechanism for resisting the vertical movement of the foot supports (30, 32). Manually gripped poles (60) are mounted to move in coordination with generally horizontal movement of foot supports (30, 32). Separate embodiments of the invention are shown in FIGS. 5-13 for performing simultaneously a stair stepping exercise and a cross country skiing or walking exercise. An alternative preferred embodiment of the invention which may be folded downwardly for low vertical profile storage is illustrated in FIG. 14.
