PowerBlock EXP 50-70 lb Adjustable Dumbbell Expansion Kit (Pair)

The PowerBlock EXP 50-70 lb Expansion Kit is an add-on pair that extends an existing PowerBlock Elite Stage 1 system to 50–70 lb per dumbbell. It uses PowerBlock's signature selector-pin adjustment mechanism (insert pin to select weight), offering 5 lb increment steps across the expanded range. Sold as a pair with steel-core plates and a compact racked footprint when stored in the included stand.

Designed for intermediate lifters already committed to the PowerBlock ecosystem, the EXP kit delivers progressive overload without buying a second full system. PowerBlock's reputation for durability and reliability in home gyms is well-earned; the mechanism rarely jams. Trade-offs: the expansion kit only works after Stage 1 purchase (not standalone), and the combined weight can feel long when dialed light. Best for lifters seeking steady weight progression in a proven, compact package.
