Enjoy the versatility of a free weights work station in the comfort of your own home with the Bowflex® SelectTech® super heavy dumbbells. With an adjustable weight range of 4-41kg, this single pair of dumbbells delivers the same results as 17 sets of weights – but without the clutter! A quick turn of the dial allows you to automatically change your resistance across 17 settings up to a maximum of 41kg per dumbbell. With such extensive versatility and the super heavy weight, they provide the most flexible strength-training options available, allowing you to gradually increase your strength. The wider weight range also means you can perform both heavy and light exercises. The result is a total body workout delivering the results you want. Featuring durable molding around the metal plates, the dumbbells are not only hard-wearing, but provide a smooth lift off. Removing the clanging of metal, you can enjoy more peaceful training allowing you to focus on your training goals. The new Bowflex SelectTech App is a great training tool which supports both iOS & Android users for the 2-24 KG (552) and 4-41Kg (1090) Bowflex SelectTech Dumbbells. Simply select which Dumbbell you have and the App will customise your experience (manual input only). If you decide to upgrade from the 2-24 KG (552) to the 5-60 KG (560)*, the App can seamlessly switch modes to support the new Dumbbell (*560 not yet available for international markets). Available in the App Store. Ergonomically designed to help protect your lower back, the included stand avoids the need to bend down to the floor to pick up your heavy weights! Complete with a large built-in media rack, just prop up your smart device, and easily access training videos, entertainment and more. Handily, its small footprint and transport castors allow for it to be wheeled away for easy storage. Please note – the tablet shown in the product images is not included.
