Summary
The closest thing to a traditional dumbbell feel in an adjustable format. Owners rave about the handle quality and small weight increments — once people buy them, they don't want to replace them.
The fastest weight-switching adjustable dumbbell on the market, scaling all the way to 100 lbs per hand. Rugged enough that Reddit's r/BuyItForLife community calls the Sport 50 'the best adjustable dumbbell ever made.'
Pros
- Traditional round dumbbell shape — most natural feel of any adjustable
- Better handle ergonomics than dial-based competitors
- Small weight increments for precise progression
- Super quick weight changes
- Aesthetically pleasing — looks like a real dumbbell
- Ultra-fast weight switching with pin selector — no dial fumbling
- Scales to 100 lbs per dumbbell on the Pro model
- Extremely rugged and long-lasting build quality
- 5 lb increments on Sport 50 model for precise progression
- Flat ends allow for push-up use
Cons
- More expensive than PowerBlock at comparable weight ranges
- Selector mechanism less rugged than PowerBlock's pin system
- Heavier/bulkier than fixed dumbbells at same weight
- Square/block shape feels less natural than traditional dumbbells
- Bulkier design limits some exercises like hammer curls
- Higher price for the Pro 100 model
Our take
If the blocky PowerBlock shape bothers you, NÜOBELLs are the answer. They look and feel like real dumbbells, and the community consensus is that owners are genuinely happy with them long-term.
If you lift heavy and hate waiting between sets, PowerBlock's pin-selector system is unmatched for speed. The Pro 100 is the go-to for serious lifters who need a wide weight range without buying a rack of fixed dumbbells.
