## Description

Whether you’re an elite competitor, pro athlete, or fitness enthusiast, performance matters. Every exercise, every minute, and every drop of sweat are valuable, and there’s no room for waste if you want to achieve results and create gains. That’s where PowerBlock adjustable dumbbells come in. Their innovative, world-class design was developed with one thing in mind: results. Engineered to feel good in your hand, adjust easily, and endure the toughest workouts, PowerBlocks are the first choice for anyone who values performance at the highest levels. Use them alone, or as a hybrid addition to your gym workouts, and start to tap into the power of PowerBlocks. The first brand to create adjustable dumbbells, PowerBlock was an industry pioneer. We challenged the world’s definition of how a dumbbell worked and what it should look like. Decades later, we’re the only expandable dumbbell trusted in elite training rooms and facilities. The PowerBlock Pro 50 dumbbells are one of the highest-rated and best-selling sets of all time. PowerBlock uses only premium-quality materials. Thanks to their smart and ergonomic design, PowerBlocks are extremely tough and can withstand all sorts of regular gym use.

Review: Would Buy Again - Very good quality. Quick and easy to change weights (large plates only). Quiet when in use. Works great with the PowerBlock Large Compact Stand (much more stable than it appears). The only cons are that adding the 2.5 lb weights is a bit cumbersome. And when both 2.5 lb weights are added to the dumbbell, you can feel that the dumbbell isn't balanced. Everything considered, I would definitely buy them again.
Review: Great portable and space-saving option! - Easy to use space saving and portable option. Right amount of weight versus the 25lb, I ended up lifting more than I thought I would over a shorter bit of time. Square shape is a little awkward at first but I got used to it after a couple of months. Thank your delivery person, it arrives in two boxes each box is 50lbs each. If you can't lift a 50lb box ensure you have help or a rolling dolly type device to get the box inside. Replacement parts available on product brand website. Excellent quality and great option, would buy other items from this company.

## Questions & Answers

**Q: Are these weights expandable I see two answers?**
A: There is the Powerblock Pro 50 which is what this is and is not EXPANDABLE. In other words the stage 2 nor 3 will fit on it. The Powerblock Pro EXP is expandable but is not available on amazon for some reason. I bought the EXP thinking it was the PRO exp and the attachments DO NOT fit it. It has to be the PRO EXP series if you want to add weight or use attachments.

**Q: Are these expandable to 70 or 90?**
A: According to the powerblock website the Pro 50 is NOT expandable, but the Pro Exp IS expandable to 70 or 90.
I have the Pro 50 and you could not expand to 70 or 90 lbs without changing every single weight plate add-on to be heavier.
The main difference I can see between the Pro 50 and the Pro Exp is the Pro 50 weights increment by 5 lbs each, whereas the Pro Exp increment by 10 lbs. So, both the Pro 50 and Pro Exp have 8 weight plates, but Pro 50 goes to 50 max in 5 lbs increments, but Pro Exp goes to 90 max with 10 lb increments. (This is assuming you leave both adder weights in the handle for every adjustment).

**Q: Are these expanded to 90 lbs each set?**
A: The PowerBlock Pro 50 is one of the non-expandable PowerBlock models.
The expandable models have a EXP in name (EXP stands for expandable).
The Pro 50 does offer every 2.5 lb increment up to 50 lbs.
Thanks.

**Q: Is this one not expandable? If not will you be selling the pro expandable block on Amazon?**
A: This set is the Pro 50 which is not expandable past 50 lbs and is not compatible with any expansion kits.  Generally, you would want to look for sets that have "EXP" in the title if you want an expandable model.  Thank you!
