PowerBlock Sport EXP Stage 1 (2.3-22.7kg) Adjustable Dumbbells

Adjustable Dumbbells

Our Take

The PowerBlock Sport EXP Stage 1 is a compact adjustable dumbbell set ranging from 2.3kg to 22.7kg, replacing up to 16 individual dumbbells. Designed for home gym users who want a serious, space-efficient free-weight solution, it sits in the premium mid-market bracket — more robust than budget selector-pin alternatives but less bulky than traditional rack setups.

Key Features

Weight range: 2.3kg to 22.7kg per hand in incremental steps

Expandable design: compatible with Stage 2 and Stage 3 add-on kits to extend up to approximately 41kg

Steel selector pin mechanism allows quick weight changes without removing plates individually

Rectangular block shape with open-centre handle — grip position stays consistent across all weights

Compact footprint; both units fit on a small tray or shelf when not in use

Colour-coded weight labels on each internal plate layer for easy identification

Our Verdict

A strong choice for intermediate home gym users who want durable, space-saving dumbbells with room to grow. The expandability justifies the price over time. Those doing high-volume isolation work or who find block-shaped dumbbells uncomfortable should consider selector-style alternatives like the Bowflex 552.

What We Like

Genuinely space-saving compared to owning multiple pairs of fixed dumbbells
Expandability means you're not locked into the initial weight ceiling
Build quality feels solid and commercial-grade for home use

Things to Consider

Rectangular block shape feels awkward during exercises like hammer curls or lying tricep work
No half-kilogram increments at lighter weights, which may frustrate beginners or rehab users
Noticeably expensive upfront compared to budget adjustable alternatives
The selector pin mechanism requires careful alignment — misloading is possible if rushed
