Abstract: A buoyant body shaped substantially as a short, flexible, columnar buoyant body, constructed from polyethylene expanded foam material having a coloring substance added to produce a colored buoyant body to enhance their use, and to facilitate color coordination with an exerciser's swimwear. The buoyant body includes a port for receiving a hand, or foot, appropriately for the particular device to be used. The port is provided centrally positioned on the buoyant body, and defines a cavity, sized for receiving the exerciser's hand or foot in a relaxed and extended manner, and thus facilitates a non-gripping securement and grip-free manipulation of the buoyant body to produce resistance in a water exercising environment. For a hand manipulated buoyant body, the defined cavity is a rectangular shaped, tapered through-hole that dimensionally conforms to the tapered shape of a hand from finger tips to beyond the knuckles and part of the palm without including the thumb.
