Abstract: An exercise apparatus has left and right foot skates which are constrained to move back and forth in reciprocal fashion. Left and right foot platforms are movably mounted on respective foot skates and constrained to move up and down in reciprocal fashion. The apparatus may be operated in different modes of operation, including a first mode, wherein the foot skates are free to move back and forth and the foot platforms are free to move up and down; a second mode, wherein the foot platforms are free to move up and down, but the foot skates are locked against movement; and a third mode, wherein the foot skates are free to move back and forth, but the foot platforms are locked against movement. Resistance may be provided to back and forth movement of the foot skates and/or up and down movement of the foot platforms.

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: In an exercise apparatus a rigid frame includes upper and lower back supports pivotally connected in axial alignment. Upper and lower back support pads are mounted on the rigid frame for supporting a user in a reclined position with the weight of the user providing resistance to the exercises. Leverage arms are mounted at the head end of the upper back support. The leverage arms extend above the rigid frame such that the free ends thereof may be grasped by the user while performing abdominal exercises. The lower back support includes handles extending outwardly from the foot end thereof for grasping by the user while performing glute exercises. A thigh pad is mounted on the upper end of a lever arm pivotally attached to the foot end of the lower back support. Upon pushing the thigh pad by the user, the foot end of the rigid frame is raised along with the body of the user. Abdominal curls or crunching exercises are performed by grasping the leverage arms and pulling up the upper back support.
