Barbell weights having a central aperture are mountable on the stem. The free end of the stem is screwed into a nut secured on the floor of the cavity.

Claims

1. A device for exercising which comprises:

a spherical block of a medium having an inner cylindrical cavity;

said inner cylindrical cavity having an opening on one end of said cylindric cavity and opening on a surface of said spherical block whereby access to said cylindrical cavity is provided;

said inner cylindrical cavity having a floor on another end of said cavity opposite said opening;

a cap dimensioned to fit over said opening;

a handle on one side of said cap;

a threaded stem having one end secured to another side of said cap and extending perpendicularly away from said another side;

a stack of at least one disk weight, insertable through said hole into said cavity;

each disk weight having a central aperture providing that said stack is mountable on said stem;

one nut screwed onto said stem on one side of said stack and another nut screwed onto said stem on an opposite side of said stack whereby said stack is releasably secured onto said stem;

means for releasably securing said stem in said cavity providing that a user is enabled to select a quantity of weights of said array for mounting on said stem.

2. The device of claim 1 wherein said means for releasably securing said array comprises:

fastening means for releasably securing another end of said stem opposite said cap to a floor of said cavity providing that a user is enabled to grasp said handle, withdraw said stem and said array of weights on said stem, from said cavity change said array of weights and resecure said changed array of weights for exercise purposes.

3. The device of claim 1 wherein said block comprises:

a shell integrally formed as a ball having an opening on its surface formed by said cylindrical cavity inside said ball wherein an interior region is formed by said shell between a surface of said cylindrical cavity and a spherical surface of said ball;

a medium filling said region.

4. The device of claim 3 wherein said medium is at least one of air, sand and shot.

5. The device of claim 1 wherein each weight of said array of weights is a disk having an aperture through its center.
