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.

Matters needing attention in barbell bending
Beginners should focus on the flexor muscles of the upper arm and use the contraction force of the flexor muscles of the upper arm to drive the forearm closer to the upper arm. Start practicing around weight 12RM. You can observe whether the action meets the requirements in the mirror while practicing, which is convenient for error correction.
After proficiency, you can observe your own brachial muscles and biceps brachii during training and constantly imagine that they will swell. After one or two exercises, you will be congested and hardened. When practicing to the extreme, you can complete the practice of 1 ~ 2 by bending your knees and kicking, swinging your body back and forth, etc.

28mm is recommended, because the Olympic weightlifting pole is 28mm', but at present, it is more 30mm or 32mm in China. In order to increase the safety load, 25mm is obviously a low-end contraction pole.
