Anti-roll design: The dumbbell plates are designed in an octagonal shape, which makes them very stable when placed on the ground. Unlike round dumbbells, they won't roll around freely, enhancing the safety of ground exercises such as push-ups.
• Rolling function: The center of the dumbbell is usually equipped with smooth bearings. With the help of side wheels or a special grip design, it can be used as an "ab wheel" for deep core stretching.
• Silent and protective: The surface is typically covered with PE, eco-friendly PP, or high-quality rubber, which not only reduces the noise when dropped but also prevents scratches on the studio or home floor.
