We've been PowerBlock dealers for over 25 years, and there's a reason for that -- they're our favorite alternative to a rack of dumbbells, and in a lot of cases, they're far superior.
The Pro series is coated in a urethane rubber that makes them safe from chipping and scratching, making these our favorite for most people. They're also expandable in stages, up to 50, 70, or 90 pounds per hand.
Powerblocks are sold in complete pairs and can be upgraded to additional weights at any time after purchase for $149. Pick your starting weight and upgrade later!
