A weight apparatus includes a bar including a handle rotatably attached to an anchorage. The anchorage includes a body and at least one radially extendable and retractable pin, the pin being movable relative to the body between an innermost position and an outermost position. An end of the pin extends radially beyond an external surface of the body when the pin is in the outermost position. The apparatus further includes a weight including a weight opening in which the anchorage is adapted to be received. The weight includes a radially extending pin opening adapted to receive the pin when the pin is in the outermost position to attach the weight to the anchorage. An arrangement is provided for driving the pin to the outermost position upon rotation of the handle relative to the anchorage.

1. A weight apparatus, comprising: a bar comprising a handle attached to an anchorage; the handle and the anchorage having an axially extending opening, the anchorage comprising a body and at least one radially extending pin, the radially extending pin being movable relative to the body between an innermost position in which a first end of the pin extends into the opening and an outermost position in which a second end of the pin extends radially beyond an external surface of the body;a rod disposed in the opening, at least a first portion of the rod having a first width and a second portion of the rod having a second, smaller width, the rod being arranged to axially move in the opening between a first position in which the first portion of the rod is adapted to contact the first end of the pin so that the pin is not movable inwardly of the outermost position and a second position in which the second portion of the rod is adapted to contact first end of the pin so that the pin is movable to the innermost position; anda weight comprising a weight opening in which the anchorage is adapted to be received, the weight comprising a radially extending pin opening adapted to receive the pin only when the pin is moved toward the outermost position to attach the weight to the anchorage. 2. The weight apparatus as set forth in claim 1, wherein the pin is spring loaded via a resilient member urging the pin to the innermost position. 3. The weight apparatus as set forth in claim 1, comprising at least two pins extending in radially different directions, the weight comprising at least two pin openings for receiving respective ones of the pins. 4. The weight apparatus as set forth in claim 3, wherein two pins of the at least two pins extend in radially opposite directions. 5. The weight apparatus as set forth in claim 1, comprising two anchorages attached to opposite ends of the handle, two rods disposed in the opening and movable in opposite directions between respective first and second positions, and at least two weights adapted be attached to respective ones of the two anchorages. 6. The weight apparatus as set forth in claim 1, wherein the rod comprises, along its length, a plurality of portions having the first width and a portion having the second width disposed between each two portions having the first width, the rod being arranged to axially move in the opening to a plurality of positions, and, in each position of the plurality of positions, either one of the plurality of portions having the first width or the portion having the second width is adapted to contact the first end of the pin. 7. The weight apparatus as set forth in claim 1, wherein the rod is non-rotatable relative to the anchorage. 8. The weight apparatus as set forth in claim 1, wherein the rod comprises a continuous, curved surface extending between the first portion and the second portion. 9. The weight apparatus as set forth in claim 1, wherein the weight is generally U-shaped so that the anchorage is adapted to be received radially in and removed radially from the weight opening when the pin is in the innermost position. 10. The weight apparatus as set forth in claim 1, comprising, a stand, the stand comprising a weight seat for the weight and a bar seat for the bar, the bar being, receivable in the bar seat in only a single position, the anchorage being adapted to be received in the weight opening when the weight is received in the weight seat and the bar is received in the bar seat. 11. The weight apparatus as set forth in claim 10, wherein the rod is movable in the opening only when the bar is received in the bar seat. 12. The weight apparatus as set forth in claim 1, comprising a second weight, the second weight and the anchorage body comprising a joint that permits radial movement and prevents axial movement of the second weight relative to the anchorage body. 13. The weight apparatus as set forth in claim 12, wherein the second weight comprises an axial opening, and the rod is adapted to be axially moved into and removed from the axial opening, the second weight being prevented from axially moving relative to the anchorage body when the rod is disposed in the axial opening of the second weight. 14. The weight apparatus as set forth in claim 12, comprising at least one third weight, the second weight and the third weight comprising a joint that permits radial movement and prevents axial movement of the third weight relative to the second weight or another third weight. 15. The weight apparatus as set forth in claim 14, wherein the second weight comprises a second weight axial opening and the at least one third weight comprises a third weight axial opening, and the rod is adapted to be axially moved into and removed from the second weight axial opening and the third weight axial opening, the second weight and the third weight being prevented from axially moving relative to the anchorage body when the rod is disposed in the second weight axial opening and the third weight axial opening. 16. The weight apparatus as set forth in claim 14, wherein the second weight and the at least one third weight are identical. 17. The weight apparatus as set forth in claim 12, wherein the joint is a dovetail joint. 18. The weight apparatus as set forth in claim 1, wherein the weight apparatus is a dumbbell. 19. A weight apparatus, comprising: a bar comprising a handle attached to an anchorage, the anchorage comprising a body and at least e radially extendable and retractable pin, the pin being movable relative to the body between an innermost position and an outermost position, an end of the pin extending radially beyond an external surface of the body when the pin is in the outermost position;a weight comprising a weight opening in which the anchorage is adapted to be received, the weight comprising a radially extending pin opening adapted to receive the pin only when the pin is moved toward the outermost position to attach the weight to the anchorage; andmeans for driving the pin to the outermost position. 20. The weight apparatus as set forth in claim 19, wherein pin driving means comprises a cam.
