Abstract: A blow-moldable container, having a centrally located, generally tubular handle spanning a central recess has improved balance and ergonomics over existing blow-molded containers. Such a balanced container has great utility as a handheld freeweight, or as a container for pourable substances. An integrally molded base allows our container to be stood upright on end like a regular bottle. Products may be marketed in such containers under the premise that the consumer automatically acquires a freeweight by purchasing the product. The inclusion of fitably engageable contours on its top and bottom surfaces makes such a container stackable with others of its kind, for ease of packaging, shipping, and storage. A graduated set of handheld fillable freeweights may thus be compactly stored without a special rack. Since blow-molding offers great economy of production for sufficiently large numbers of containers, the average person will now be able to afford an entire graduated set of freeweights.

A user can replace the weights with other ones of different weight volume. If the dumbbell should fall down on the ground, it might not produce sound because of flexibility of the weights, not hurting a user or a person around, the ground surface or the weights, and thus very safe to use.
