Expand to Elite-Level Strength Training — Designed for COMMERCIAL GYMS
The PowerBlock Commercial Pro 125–175 Expansion Kit is designed for COMMERCIAL GYMS and advanced training facilities looking to push strength training beyond limits. This expansion kit upgrades your Commercial Pro 125 Adjustable Dumbbells to a massive 175 lbs per hand, unlocking new possibilities for heavy lifting and progressive overload.
Built for serious lifters, this system supports advanced exercises such as heavy presses, rows, deadlifts, and high-load functional movements, making it ideal for elite athletes and high-performance training environments.
Like all PowerBlock systems, the expansion kit utilizes a commercial-grade magnetic selector pin for fast and secure weight adjustments, minimizing downtime between sets and maximizing training efficiency.
Constructed with rugged, commercial-grade materials, the Pro 125–175 Expansion Kit is engineered to withstand high-volume use in demanding gym environments while maintaining long-term reliability.
By expanding your existing dumbbell system rather than adding more equipment, this kit provides a space-saving solution that eliminates the need for multiple heavy dumbbell pairs.
