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 set up to 90lbs. An expandable model starts at 50 pounds and then gives the option to expand with two 20 pound kits. The ‘Stage 2 Kit’ will take a 50 lbs. set up to 70 lbs., while a ‘Stage 3 Kit will take a 70 lbs. set up to 90lbs.

Models NOT expandable include:

  • Sport 24, Sport 50, PowerBlock 50
  • Classic 50 Set, Personal Trainer Set
  • Pro 32, Pro 50

If you are unsure if your model can accommodate an expansion kit, please call customer service at 1(800)997-3999.
