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 appara

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 (41 F, 41 G) 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 (41 H-41 1). 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).

[ What is claimed is:] [1.] An exercise device, comprising:a base frame designed to occupy a fixed position relative to a floor surface during exercise activity;a first body support having a support surface which faces generally away from said floor surface and is arranged and designed to support a person's upper back, wherein said first body support is rotatably connected to said base frame and rotatable relative thereto about a first pivot axis;at least one handle arranged and designed for grasping, wherein said at least one handle is disposed within reach of a person supported in supine fashion by said first body support, and said at least one handle is constrained to rotate together with said first body support relative to said base frame;a second body support arranged and designed to support a person's feet, wherein said second body support is accessible to a person supported in supine fashion by said first body support, and said second body support is rotatably connected to said base frame and rotatable relative thereto about a second pivot axis, and said second body support is operatively connected to said first body support in such a manner that rotation of said support surface about said first axis and toward said second body support causes said second body support to rotate about said second axis and toward said support surface; anda third body support arranged and designed to support a portion of a person's torso, wherein said third body support is disposed between said first body support and said second body support.
