Pro 100 EXP Stage 3 Kit (up to 36.3 kg)

Warning: Order cancellations and returns are subject to a 20% processing/restocking fee. 

This kit is only compatible with the Pro 100 EXP Stage 1 and Stage 2 (2.3–27.2 kg) dumbbells.  If your dumbbells say Pro 100 EXP and currently max out at 27.2, this kit fits. 

It will not work with any other PowerBlock models.  Check compatibility here.  If you are unsure of compatibility, please contact customer service.

  • A pair of Pro 100 EXP Stage 3 weights (one for each dumbbell) in a single box
  • Blue and red color‑coded side rails for quick weight identification
  • Everything needed to expand your existing Stage 1 and Stage 2 set to 36.3 kg per hand

Add weight only when you’re ready to lift more by locking your expansion kit smoothly into your Pro 100 EXP setup with the same welded steel stability you already trust. The expansion kit supports steady, long‑term strength increases in a compact, budget‑friendly home gym.

Take your Pro 100 EXP Adjustable Dumbbells even further with the Stage 3 Expansion Kit. Sold in pairs, this kit includes two 4.5 kg additional weights per dumbbell, increasing your base Pro 100 EXP set from 27.2 kg to 36.3 kg. This expansion requires the original Pro 100 EXP set and the Stage 2 Expansion Kit before adding Stage 3 for a complete upgrade.

Key Features:

  • Increases weight from 27.2 kg to 36.3 kg per dumbbell.
  • Sold in pairs for both dumbbells.
  • Requires Stage 2 Expansion Kit and Pro 100 EXP set for full compatibility.
  • Ideal for advancing your strength training as you progress.

What is the benefit of adding the Pro 100 EXP Stage 3 expansion kit?

Stage 3 expands your Pro 100 EXP set to include 70 lb and 80 lb weight plates. This makes it easy to progress into heavier compound lifts like squats, deadlifts, bench presses, and heavy rows, simply by purchasing the next expansion level instead of replacing your dumbbells or taking up more space.

Does the Pro 100 EXP Stage 2, Stage 3 or Stage 4 kits work with other other PowerBlock sets?

No. The Pro 100 EXP Stage 2, Stage 3 and Stage 4 kits will only work with the Pro 100 EXP set.

Does the Pro 100 EXP Stage 3 Kit have to be purchased before Stage 4?

Yes. The Pro 100 EXP Stage 1, Stage 2 and Stage 3 must be purchased in order to use subsequent Pro 100 EXP expansion kits.

Are expansion kits sold in pairs?

Yes. When an expansion kit is purchased, there are enough weight plates included to expand both dumbbells.

Does the Pro 100 EXP Stage 1 and Pro 100 EXP Stage 2 have to be purchased to use the Pro 100 EXP Stage 3 kit?

Yes. The Pro 100 EXP Stage 3 is an expansion kit and the Pro 100 EXP Stage 1 and Pro 100 EXP Stage 2 are required for this expansion kit to work.
