Patent attributes
An exercise machine (10-101) is provided having a platform (12-121) on which a user (14-141) 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 (10-101). A lever (20-201) is pivotally connected (30-321) to the platform (12-121) with the lever being actuated by the user for raising one end of the platform (12-121) with respect to a pivot point with resistance to such raising being varied by the pivotal mounting of the lever (20-201) on the platform (1 2121). 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-20i) having telescoping members with an inner one (54H-541) for such telescoping member being selectively fixed to a rail (41H-411). Such inner telescoping member (54H-541) reciprocates within an outer telescoping member (56H–561) 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. A further embodiment of the invention (FIGS. 23–27) includes an upper back support (210) interconnected by a connecting linkage with a lower body actuator (240) for coordinated simultaneous movement upon a lifting action exerted by limbs of a user against either the upper back support (210) or the lower body actuator (240).
