PowerBlock U-90 Club Set
Power Block is the grandfather of adjustable dumbbells which shows in the quality of their products and this weight set is pure magic. Though Power Block has a stable of adjustable dumbbells, I singled out the U-90 Stage 1 for a few key reasons. This set can go from from 5 to 50 pounds in 2.5 pound increments and can be added onto up to 125 pounds which makes it one of the highest weight adjustable dumbbells available. It uses a unique weight and pin system which is not only super simple to use but prevents the weights from moving at all during your workout. These weights are incredibly durable as they are steel covered by highly durable plastic which can handle all sorts of punishment in the weight room. While some users have said they don't like the way the dumbbell handles fit, this is still a great set which is also backed by a lifetime warranty.
