Abstract: A weightlifting device allowing for a variety of bodyweight exercises to be performed. The device having a foundation and support bars. Hinged arms and a cage extend from the support bars. The cage is adapted to hold an exercise ball. A crossbar is attached to the support bars as well as adjustable abdominal straps.

Abstract: A weight lifting power cage for use by a weight lifter includes a floor frame assembly including a pair of side floor frames, a front lateral floor frame member, and a rear lateral floor member. A carriage is carried by the side floor frames and is movable simultaneously vertically and front to back. The carriage retains a weight bar mount for retaining a weight bar spanning between each side frame. The weight bar is movable by the carriage vertically and front to back. The movable carriage also carries a pair of vertical weight rack bars. An engagement mechanism enables the weight lifter to rack the weight bar from a weight lifting position without stepping forward or backward.

Abstract: A weight bar slide assembly, for use with weightlifting equipment having vertical guide bars that provide for an accurate simulation of the free weight lifting motion. The weight bar slide assembly has a weight bar sleeve to rotatably receive a weight bar. A rod is attached to the weight bar sleeve and extends outwardly therefrom. A rod sleeve rotatably receives the rod. The rod may rotate along its longitudinal axis inside the rod sleeve. The rod sleeve is attached to a vertical guide. The vertical guide is movably mounted to a vertical guide bar. The longitudinal axis rotation of the rod within the rod sleeve allows for the freedom of motion found in the free weight lifting motion. The weight bar slide assemblies attached to opposing ends of the weight bar may move linearly along the vertical guide bar independently of each other.

Abstract: An exercise gymnasium is composed of a frame assembly, a movable pivot arm assembly carried by the frame assembly, and a press arm assembly carried by the pivot arm assembly. The press arm assembly includes an inverted U-press arm that includes a pair of press arms and is rotationally attached to the pivot arm. A pair of handles for hand grasping by a user is provided. Each of the press arms carries a track assembly affixed to the handles. Movement of hte handles is restricted to vertical movement by the track assemblies.
