Abstract: A reciprocating exercise device for strengthening of the muscles comprising the shoulder. The device is held in the user's hand and moved in a repeated manner to simulate a sports specific movement or for therapeutic muscle strengthening. A tube with detachable end caps contains a weight. The end caps house springs that extend into the tube when attached to the ends of the tube. The weight is of a diameter such that it may travel freely along the inner length of the tube, yet closely matched to the inner diameter of the tube such that significant air compression occurs in front of the moving weight. The generated air compression serves to reduce the shock of the weight when it impacts the springs at the tube ends. Controllable tube venting allow for control of the magnitude of this effect. Variable styles of attachable handles allow for improved simulation of sports specific throwing motions.

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.

Abstract: Stackable weight plates comprised of a front and a rear lateral faces with a protrusion at a proximal radial center of the front lateral face and corresponding recess at a proximal radial center of the rear lateral face is provided. The rear lateral face with the recess section at the proximal radial center of a top weight plate in a stack may rest (or be stacked) on the front lateral face with the protrusion at a proximal radial center of another weight plate. Because each plate is restrained along its center axis by the mating or interlocking of the protruded area of one plate with the recessed area of another weight plate, the stacked plates are therefore generally stable and do not fall due to lateral shearing of the stack. When mounted on a handle bar to form an inertial force exercise device, the recessed area of the rear lateral face of the weight plates of the present invention house the mounting or fastener mechanism.

Abstract: An exercise dumbbell system includes a handle and weight plates maintained in spaced relationship at opposite ends thereof.
