Glue is more expensive, n sells more, and the heavier one is at least in 200 yuan. Guangzhou only needs 30 kg, or it is also available at the entrance of Heping Road Provincial Stadium. I want to buy a second-hand barbell, but the quantity you see is wrong. There is a second-hand market near Fuyuan Huacheng. Elastic ropes can be tied to both sides of dumbbells to increase the weight. You can also buy it second-hand.
