The Power Block Flex Urethane Series U90 Dumbbell Set

The versatility of the U90 Dumbbell Set is due to the adder weights within the core handle of each dumbbell. On their own the two adder weights each weigh 1kg and the empty handle weighs 2.5kg and so even before any of the weight plates are used, you can train in 1kg, 2.5kg, 3.5kg and 4.5kg increments per hand.

So if your goal is to gain strength, develop power, reshape your body or prevent injuries by strengthening the stabilising muscles around your joints - free weight training with the Power Block U90 will be your most effective workout.
