With an adjustable weight range of 4-41kg; this dumbbell delivers the same results as 17 single weights - but without the clutter! Featuring a handy dial; you can adjust your resistance with ease across 17 settings. Starting at 4kg all the way up to a massive 41kg; you have the versatility to perform different exercises and gradually increase your weight. It's the most flexible strength-training option available. The result is a total body workout delivering the results you want. Highly robust; the dumbbell features durable molding around the metal plates; which has the dual benefit of providing a smooth lift off.
