Maximize the effect of your PowerBlock Pro workout. If you’ve already added the Stage 2 Expansion Kit (50 – 70 LB), take it all the way with an upgrade to the PowerBlock Stage 3 Expansion Kit.

This add-on takes you up another 20 LB – from 70 to 90 LB per dumbbell. The PowerBlock Pro Urethane series (AKA EXP Pro Series) was designed in three stages to allow users to save up and move up when they’re ready for that next challenging level. The Stage 2 add-on is required to advance to stage three.

It’s the final progressive step in a system that employs strong, flexible construction and one of the quickest weight selection technologies available for adjustable dumbbells – making for a fluid and effective workout.
