There's a few reasons why Xpeed Rubber Hex Dumbbells are one of the most popular gym products around. The infamous rubber coating reduces noise in the home gym. In addition, the rubber coating also improves the life cycle of the dumbbells themselves. Coatings such as chrome or cast iron are prone to chipping, whereas rubber coated dumbbells are kinder to different gym floor surfaces. Experience increased comfort and improved durability during your workouts thanks to the contoured dumbbell handle. A key safety feature is the hexagonal shaped ends, which are designed to stop the dumbbells from rolling away on the floor or falling off of the dumbbell rack.
