PowerBlocks are the easiest adjustable dumbbells to expand, so as your strength grows, they can too. If your PowerBlock is an “EXP” model then you’ll be able to increase the weight of your dumbbells with additional 4.5 kg. weights, sold in pairs called Expansion Kits. PowerBlock Expansion Kits come in two stages, and you must add stage 2 before adding stage 3.
NOTE: These PowerBlock models are NOT expandable:
- Classic 50 Set
- Personal Trainer Set
- PowerBlock 50
- Pro 32
- Pro 50
- Sport 24
- Sport 50
If you are unsure if your model can accommodate an expansion kit, please call customer service at 1 (800) 997-3999 Office Hours (GMT): 14:30-23:00 (Mon-Fri).
