About
What it is.
Part of PowerBlock's PRO line, the Pro 100 EXP Adjustable Dumbbells use the brand's signature selector-pin block system, letting a lifter dial in a load by sliding a pin rather than swapping plates. The "EXP" designation refers to the expandable design, which allows the block to grow in capacity beyond its standard range while keeping the same stackable, rectangular footprint that PowerBlock is known for.
Built for home gym owners who need heavy resistance without dedicating a room to a full rack of fixed-weight dumbbells, this set trades the rounded feel of traditional dumbbells for compact storage and long-term durability. It suits lifters progressing toward serious strength numbers, rather than those who prioritize hand comfort or a classic barbell-style grip.
The verdict
The PowerBlock Pro 100 EXP offers a durable, premium-feeling adjustable dumbbell with fast magnetic pin adjustment and a thick handle suited for pressing, though its bulky footprint and higher cost make it better suited to committed home lifters than those seeking a compact, traditional feel.
