Abstract: An exercise machine (10-10l) is provided having a platform (12-12l) on which a user (14-14l) is supported in a reclining position with the weight of the user (14-14G) being utilized as a resistance which may be selectively varied to the various exercises which may be performed on the exercise apparatus (10-10l). A lever (20-20l) is pivotally connected (30-32l) to the platform (12-12l) with the lever being actuated by the user for raising one end of the platform (12-12l) with respect to a pivot point with resistance to such raising being varied by the pivotal mounting of the lever (20-20l) on the platform (12-12l). Two of the various embodiments (FIGS. 13-16) include a base support (41F, 41G) having a rail (42F, 42G) on which a lever (20F, 20G) has a roller (47F, 47G) mounted for riding movement thereon and pivotally connected (32F, 32G) to a lower leg (62F, 62G) for pivotal movement. Other embodiments (FIGS.

Abstract: An exercise device (10) has a handlebar (30) with handgrips (32) for gripping by a user (U). An adjustment plate member (26) is mounted for pivotal movement about a pivot (28) on a fixed support plate member (18). A seat (58) supports the weight of the user U to resist to the rotation of the adjustment plate (26). A generally horizontal exercise movement is performed by pulling on the handlebar (30) and simultaneously pushing on foot pedals (70) on a foot frame (68) secured to the adjustment plate member (26). The horizontal exercise movement shown in FIGS. 1 and 2 can be easily converted to a vertical exercise movement shown in FIG. 3 at the discretion of the user (U) by changing the motion exerted against the handlebar (30) by the user (U).

Abstract: An 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. Another embodiment illustrated in FIGS.

Other embodiments include a lever having telescoping members with an inner one of such telescoping member being selectively fixed to a rail. Such inner telescoping member reciprocates within an outer telescoping member as the platform is raised and lowered.
