The weight bar assembly 300 comprises a bar 1, an extension bar 2, a weight 8, and a retaining clamp 10. In one example, the weight 8 is of a disk shape. In one example, the weight 8 is made by a single piece construction (for example, by a single casting process). In one example, the weight 8 is a slidable weight disk configured to be directly attached to the bar 1 by the retaining clamp 10. In one example, the extension bar 2 is shorter than the bar 1.

FIG. 4 shows a perspective view of the weight bar assembly 300 of FIG. 3 in an assembled condition in examples of the present disclosure. The bar 1 is connected to the extension bar 2. The weight 8 comprises a central hole 9. The weight 8 is mounted on the bar 1 through the central hole 9 of the weight 8.

Referring now to FIGS. 1, 3 and 4, a weight bar assembly 300 comprises a first bar 1, an extension bar 2, and a weight 8. The first bar 1 comprises an elongated cylindrical shaft 3 and a collar 5. A diameter of the collar 5 of the first bar 1 is larger than a diameter of the elongated cylindrical shaft 3 of the first bar 1. The collar 5 of the first bar 1 divides the elongated cylindrical shaft 3 into a first exposed portion 310 and a second exposed portion 330 opposite the first exposed portion 31. The first exposed portion 310 of the elongated cylindrical shaft 3 is longer than the second exposed portion 330 of the elongated cylindrical shaft 3.

In examples of the present disclosure, the first exposed portion 310 of the elongated cylindrical shaft 3 comprises a first constant outer diameter. The second exposed portion 330 of the elongated cylindrical shaft 3 comprises a second constant outer diameter. A value of the first constant outer diameter equals to a value of the second constant outer diameter.
