The York commercial 20kg (44lbs) rubber hex dumbbell utilises rubber coated heads ensuring protection for the floors and surrounding equipment, as well as diminishing the noise. The fabulous anti-roll design prevents the dumbbell from rolling away, while the torque threaded heads are permanently attached to a thick (35mm) solid steel shaft in order to improve the strength of the head/handle joint. The dumbbell is easy to clean and is perfect for building strength and muscle toning. Additionally, the product is sold individually and suitable for light commercial usage only.
