Abstract: A shell assembly configured for holding one or more weighted articles includes an outer shell having an outer surface and an inner surface defining a cavity configured for receiving the article(s) therein, with an opening providing access to the cavity, a closure configured for selectively opening and closing the opening, and a securing structure configured for securing the article(s) within the cavity to limit movement of the article(s). The securing structure includes a plurality of adjustable straps each connected to the inner surface of the outer shell at a first securing point and a second securing point on opposite sides of the opening. Each of the straps is adjustable with respect to the outer shell to increase or decrease an effective length of the respective strap between the respective securing points, to increase or decrease a distance between the respective securing points and thereby constrict or expand the outer shell.

Abstract: A monolift assembly includes a carriage assembly configured to be releasably secured to a post of a rack for weightlifting equipment. A pivoting piece is pivotally connected to the carriage assembly and has a hook at a first end thereof and a counterweight at a second end thereof. The pivoting piece includes a central plate, a first exterior plate abutting a first side of the central plate and a second exterior plate abutting a second side of the central plate.

Abstract: A weightlifting machine that includes a pulley system and a cable system that attaches to a weight rack frame to allow a user to perform a weightlifting exercise. The pulley system may include a first pulley and a second pulley where the cable system engages each pulley. The cable system may have a first end connected to a grip attachment and a second end attached to a resistance element. The resistance element may include a resistance band, a weight support that holds a weight plate, a set of weight plates, or other type of resistance element. The cable system may extend from the pulley through an opening located one of the frame members that form the frame. A seat attachment assembly may also be connected to the weightlifting machine, where the weightlifting machine may include a pulley rotatably connected to a seat base that supports a seat.
