Abstract: A top weight adapted for vertical adjustment when disposed at the top of a weight stack in a suspended weight exercise machine having guide rods on which the weight stack slides, and a central pick-up rod which engages the weight stack for suspension thereof. The top weight includes a plurality of cavities open at the bottom to permit installation of insert weight plates therein. A slot opening extending through the entire width of the top weight permits vertical adjustment of the central pick-up rod when the top weight is mounted thereto along a vertical direction. This vertical adjustment accommodates manufacturing tolerances in the weight stack which would otherwise prevent a selector pin from interconnecting the weight stack to the central pick-up rod.

Abstract: An exercise device for performing both sit-up and hyperextension exercises has a frame with front and rear base members and front and rear inclined portions that extend downwardly from an apex toward the front and rear base members, respectively. A back pad is pivotally mounted to the rear inclined portion of the frame and is adjustable over a range of declination angles. The front inclined portion of the frame includes a slideable member that is telescopically adjustable. A cushioned pad is transversely disposed at the upper end of the slideable member and serve as both a knee support for performing abdominal exercises and an upper thigh support for performing hyperextensions. Below this cushioned pad, a similar cushioned pad is pivotally attached to the slideable member to serve as a foot restraint when performing abdominal exercises. This same cushioned pad may be rotated against the first such pad to provide additional support for the operator's upper thighs when performing hyperextensions.

Abstract: An exercise apparatus includes a plurality of exercise stations, each of which exercises particular muscle groups of the body. Each exercise station is continuously coupled to a common stack of weights, a selectable number of which provide resistance to a user's operation of a selected exercise station. At least one of the exercise stations is coupled to the weight stack through a lever arm. A plurality of lever arms may be provided and mechanically interconnected so as to couple a plurality of exercise stations to the weight stack.

Abstract: An exercise apparatus for performing a variety of exercises, including chest and incline shoulder press exercises during which the user sits on a seat with a backrest which is adjustably secured in upright and forwardly inclined positions for supporting the user's upper body in the proper positions for these exercises. The exercises all utilize the same weight stack or other device for resisting the exercise motions of the user. The apparatus has a plurality of exercise members mounted on a frame for different prescribed exercise movements by the user, a resisting force producing arrangement, and a cable for selectively connecting the resisting force to the different exercise members. The cable is guided and supported by pulleys, one of which is adjustable from one position to another to accommodate the different exercises.
