A hand held exerciser and key chain assembly includes a ball body having a plurality of elastomeric balloon layers and a particulate material packed within an innermost balloon layer. The balloon layers each have an opening therethrough. An inner attachment member having an outer diameter greater than the diameter of at least the opening of the outermost balloon layer is situated within at least the outermost balloon layer. An outer attachment member is snap engaged to the inner attachment member. A loop is connected to one of the attachment members and extends through the opening in at least the outermost balloon layer. A key chain is attached to the loop. As a result, an interesting and structurally sound hand held exerciser with key chain assembly is created.
