1. An exercise assembly comprising:
a core bladder having a sealed body supporting a valve that permits fluid communication with a fluid-receiving cavity of the sealed body for selective arrangement of the sealed body in one of a compact deflated state or an expanded inflated state;
an outer case formed by a plurality of panels defining a core bladder receiving cavity that contains the core bladder; and
wherein the outer case includes a first opening that cooperates with a closure element that provides selective access to the core bladder receiving cavity and a second opening that is sized for permitting access to the valve;
wherein the plurality of panels that form the outer case includes a top panel that is configured to include a dome-shape when the core bladder is arranged in the expanded inflated state; a bottom panel that is configured to include a bowl-shape when the core bladder is arranged in the expanded inflated state; and an intermediate ring-shaped panel connecting the dome-shaped panel to the bowl-shaped panel, wherein the intermediate ring-shaped panel defines the first opening that provides selective access to the core bladder receiving cavity, wherein one of the dome-shaped panel and the bowl-shaped panel defines the second opening that is sized for permitting access to the valve; and
wherein one or both of the top panel and the lower panel includes a frictional, slip-resistant portion, wherein the frictional, slip-resistant portion further includes a silicon gel pattern arranged over a lightweight denier material.
