Our Take
The PowerBlock Pro 90 is a premium adjustable dumbbell system replacing a full rack of weights up to 90 lb (approximately 40 kg) per hand. Aimed at serious home gym enthusiasts who train regularly and need a wide weight range without sacrificing floor space. It sits firmly at the upper end of the consumer market, competing with Bowflex and NüoBell.
Key Features
Adjustable from 5 lb to 90 lb (roughly 2.3 kg to 40.8 kg) per dumbbell in incremental steps
Selector pin mechanism allows fast weight changes without removing individual plates
Compact, block-style design keeps footprint significantly smaller than a traditional dumbbell rack
Steel and durable overmoulded construction with a distinctive open-centre frame
Compatible with optional PowerBlock stand and curl bar attachment, sold separately
Weight increments are relatively fine in the lower ranges, becoming broader at heavier loads
Our Verdict
An excellent investment for committed home gym users who train consistently and need broad weight coverage without the space or expense of a full dumbbell rack. If you're a beginner, train infrequently, or find the price difficult to justify, a more affordable adjustable set will serve you better.
