Livepro’s advanced polyurethane dumbbells are well suited for free-strength training. They are made of alloy steel handles that are completely pressed to each solid steel head and welded outside to achieve maximum strength. This also avoids any needed damage and repair. The head is wrapped by a 12mm thick polyurethane later that is shock absorbing and impact resistant. It better protects the floor and the surrounding equipment. The middle level rolling design of the handle surface is improved and the gripping is very comfortable. It can be gripped even if one’s hand is sweating during exercise. The dumbbell is treated with hard chrome coating that is not only beautiful, corrosion resistant, and durable. They are a good choice for commercial or household use.
