In an adjustable weight exercise device for body building and therapy for use in strengthening hands, arms, chest and the neck of a person using the same, said device including a central annular bar having a pair of ends and each end including weight stop means and projecting outwardly beyond said stop means each end having weight receiving shank portions, and a pair of annular disk weight members having exterior and interior surfaces and each mounted on one of said shank portions all on a common central horizontal axis and with said interior surface abutting said stop means, the improvement including:
- weight locking-holding means affixed to the exterior surface of each of said weights to hold said weights to said central annular bar, and a pair of auxiliary disk weight extensions projecting outward from said exterior surface of each of said weights and on said common central horizontal axis;
- a pair of auxiliary annular disk weights each having an exterior and interior surface and a diameter and each adapted to be releasably secured to each of said weight extensions, each of said auxiliary annular disk weights including a recess in said interior surface adapted to fit on said weight extensions and be maintained on said common central horizontal axis thereon until manually removed, whereby the total weights of said exercise device may be varied.
In a dumbbell for body building or therapy, a central annular bar having a pair of ends and each end including weight stop means and each end having a weight receiving shank portion, and a pair of annular disk weight members with exterior and interior surfaces and a central bore therethrough, each of said weights being mounted on said shanks through said central bores and abutting said stop means, the improvement including;
- a lock and auxiliary weight receiving collar abutting the exterior of each of said disk weights with a set screw passing through said collar and said weight into said bar to lock said weight in place, said collar including an exterior annular threaded surface projecting outwardly from said weights;
- a pair of auxiliary annular disk weights each having an exterior and interior surface and including a centrally positioned threaded recess projecting inwardly from said interior surface and terminating before said exterior surface, each of said auxiliary annular disk weights releasably fitted on each of said collars by said threaded recess, whereby the total weight of said dumbbell may be varied.
