LIVEPRO Performance Weightlifting Bar is stylish and has a huge tensile strength. The 4 rollers enhance the rotation force while reducing friction and wear. The surface layer of the sleeves are electroplated, making the surface smoother, more beautiful, and easier to load and unload plates onto. The electroplated grip ensures the corrosion resistance of the poles. The medium level knurled design on the surface handles improves the grip and comfort. Even if the palm of the hand sweats during exercise, the barbell can still be firmly gripped.
