[0001] The utility model belongs to the technical field of barbell bars, in particular to a fracture-proof and collapse-proof barbell bar. Background Art

[0002] Barbell is a core training exercise equipment. Barbell exercise is a type of weight training that is used to increase muscle strength. Barbells can also be used for core training to promote overall coordination.

[0003] At present, when operators are doing arm strength training, they often use relevant barbells to assist in the training. The barbell is usually composed of a barbell rod and barbell plates. Due to the weight of the barbell plates, operators are usually accustomed to putting the barbell down directly after pulling the barbell. At this time, the barbell plates will directly contact the ground. At this time, the barbell rod will be subjected to a great impact force due to the barbell plates. At this time, the barbell rod will break after a long time, so it needs to be improved. Utility Model Content
