Our Take
An expansion kit designed to extend the weight range of the PowerBlock Sport EXP Stage 1 adjustable dumbbell set. It adds heavier weight increments to an existing pair, making it suitable for intermediate to advanced lifters who've outgrown their current range. It's a cost-effective upgrade path rather than a standalone product, and only compatible with the Sport EXP system.
Key Features
Extends the Sport EXP Stage 1 dumbbells from 24kg up to approximately 36kg per hand
Adds weight in increments consistent with the existing PowerBlock selector-pin system
Uses the same magnetic selector-pin adjustment mechanism as the base set
Weights slot into the existing cradle structure — no separate stand required
Steel construction with PowerBlock's familiar rectangular block format
Compatible exclusively with the Sport EXP Stage 1 base set, not other PowerBlock models
Our Verdict
A sensible buy if you already own the PowerBlock Sport EXP Stage 1 and have genuinely hit its weight ceiling — it extends your range efficiently and affordably by comparison to alternatives. If you don't own the base set or lift significantly heavier, look at purpose-built heavy adjustable dumbbells instead.
