What’s the benefit of the Pro EXP Stage 2 Expansion Kit?

Adding Stage 2 expands your Pro EXP dumbbells from 50 lbs to 70 lbs per hand, giving you heavier options as your strength increases. It’s ideal if you’re outgrowing the 50 lb range and want more room to progress on compound lifts like presses, rows, squats, and lunges. Expanding your set in steps lets you increase weights as you get stronger without replacing your dumbbells.
