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. 17-18 include a lever (20H-20l) having telescoping members with an inner one (54H-54l) for such telescoping member being selectively fixed to a rail (41H-41l). Such inner telescoping member (54H-54l) reciprocates within an outer telescoping member (56H-56l) as the platform is raised and lowered. Another embodiment of the invention includes a lower body frame which may be rotated with lower limbs, an upper body frame which may be rotated with upper limbs and a weight stack-cable system for resisting rotation of the lower body frame and/or the upper body frame.
