These solid and durable DKN dumbbells weigh 6kg (13.2lbs) each and guarantee a comfortable grip thanks to ergonomically shaped knurled handles produced from steel. They are designed for increasing muscle mass and bone strength, as well as for gaining more power and lowering blood pressure. Added safety is ensured by an anti-roll hexagonal design, whereas protection of flooring and surrounding equipment is provided by pinned cast iron rubber encased heads. The dumbbells are supplied as a pair.
