PowerBlocks are the world's best dumbbells. Why? PowerBlocks are perfectly balanced. They are the heaviest, most compact, and easiest to use quick change dumbbell. PowerBlock is the only dumbbell system that can expand to meet your strength needs. Start with a 50 lb. set, expand to 90 lbs., expand again to 125 lbs. Dumbbells are the most versatile and effective exercise tool ever developed for strength training. Now you can have rapid access to a whole rack of dumbbells at home in the space of just one pair, and at a fraction of the price of conventional dumbbells.

The Flex Series Urethane Sets from PowerBlock are the fourth generation of PowerBlocks. The Urethane coated weight plates offer the ultimate in smooth, quiet performance in addition to Flex technology (patent pending) in both the weight plates and the selector pins making for the most durable PowerBlock ever. The steel side colored rails are powder coat painted and are on both sides of each block. Urethane Series products carry a lifetime home warranty.

The U-33 Set is a component based set that can expand in weight to meet the needs of the user. You can start with the U-33 Stage I, 1-21 lb set. This set can then be expanded later to 33 lbs per hand using the Stage II Kit.
