The usage of the hexagonal barbell is the same as the ordinary barbell, but it is a new type of barbell with a unique shape, which is more convenient for exercise than the traditional Olympic barbell. The regular color is silver, but you can also make it black if you need it. It complies with international standards. Exercise is more beneficial to our bones. We are the source manufacturer, so we can customize the size and pattern, and the price is cheaper. Of course, if you have special requirements, you can tell us. If you don't want this shape, you can send us the drawing. Because we have our own engineers, we also produce dumbbells, kettlebells, environmentally friendly kettlebells, barbell plates, I look forward to your email my friend.
