ABSTRACT:
The disclosure embraces an exercising device such as a weight lifting device referred to as a barbell and an exercising device of a so-called dumbell type. The exercising device comprises a pair of housings mounted on a bar, each housing adapted to contain annularly-shaped weights in concentric nested relation with the innermost weights mounted on the bar and the housings secured to the bar. Each housing is provided with a cover supported on the bar and secured to the bar by releasable means. The annular nested weights in each housing are prevented against relative movements, the arrangement of weights in a housing being subject to any combination of a weight or weights with the retained weight or weights in a housing but restrained against movement in a housing and thereby render each housing and weight assembly of variable weight as desired by a user of the exerciser or weight lifting device.
