PowerBlock’s Flex U-90 and U-90 Club Set are the premium models within the Powerblock range. Both models within the Flex Series carry a full 15-year home warranty but the Flex U-90 comes with an additional 3-year commercial warranty.
Manufactured from solid steel, each weight plate in the Flex Series models is coated in urethane. This covering ensures the dumbbells will stay in excellent condition for many years to come as the urethane protects the plates from chipping and cracking, even if dropped or banged together, during workouts.

In addition to the urethane coating and what makes the Flex Series suitable for commercial environments is its patent protected* flex-pin and flex-plate technology. With no welds and the ability to bend and ‘flex’ under pressure, both the selector pin and weight plates, have this energy absorbing technology to ensure the longevity of the dumbbell system.
It is this flex-pin and flex-plate technology that differentiates the Powerblock Flex Series dumbbells from any other weight system
