Classification of barbells

There are two kinds of barbells: standard barbells and non-standard barbells.

1. standard barbell: composed of barbell bar (bar), barbell piece and clip. International weightlifting competitions must use international standard barbells recognized by the International Weightlifting Federation, including men's barbells and women's barbells. The difference is mainly in the barbell bar, and the barbell piece is a standard. Men's barbell bar is 2.20 meters long,

Weight 20kg, women's barbell bar length 2. 15m, weight 15kg. The diameter of barbell bar is 0.028 m, and the largest barbell piece is 0.45 m. Adding rubber to the outer bread can increase the appearance and reduce the noise of barbell landing. The weight, color and model of barbell pieces are as follows: 25 kg (red large size), 20 kg (blue large size), 15 kg (yellow large size).

10 kg (big green), 5 kg (medium white), 2.5 kg (small red), 2 kg (small blue), 1.5 kg (small yellow), 1 kg (small green), 0.5 kg (small white). The weight values of all barbell pieces must be numbered on the outside.

Each clamp weighs 2.5 kg [1]. The rule of adding barbell pieces is that the inner side (added first) is heavier than the outer side (added later), that is, the weight is added to the inner side and the weight is added to the outer side. Because the weight of the clip is 2.5 kg, it is necessary to add small barbell pieces below 2 kg (including 2 kg) outside the clip, and each side of such small barbell pieces is limited to 1 piece.

2. Non-standard barbell: The structure is the same as the standard barbell, and the size requirements are not strict, and the production requirements are not high. The weight can be freely specified, and the stone burden used by the people can also be replaced. In addition, in order to meet some special requirements, if you need to develop muscles in a certain part, you can make various types of special barbells (such as bending barbells, bow barbells, ring barbells, etc.). ) as needed.
