PowerBlock Pro 50 Adjustable Dumbbells

PowerBlock

4.5

(282)

Very Good

PowerBlock's 5-50 lb pair: pin-selected in 2.5 and 5 lb steps, in a compact nested-cage shape. PowerBlock sells the Pro 50 as a fixed-range set that cannot be expanded past 50 lb per hand, so a lifter who expects to outgrow it should look at the expandable Pro 100 EXP instead. Utilitarian looks, 5-year residential warranty.

Bowflex Results Series 1090

Bowflex

3.9

(13)

Good

10-90 lb adjustable single dumbbell — the widest range in the consumer-tier dial category, and the only 90 lb dumbbell we rank. This is the Results Series 1090, BowFlex's 2025 redesign: the original SelectTech 552 and 1090 were recalled in June 2025 (CPSC; plates could come loose from the handle), and the Results Series models were the replacement. Same dial idea, heavier internals and a larger handle. The Amazon listing is a single dumbbell (BowFlex.com sells the 1090 as a pair). 3.9 from 13 ratings since the 2025 relaunch, too few to score; re-checked 2026-11-21.

Pros

+ 10-90 lb in 5 lb increments — covers most adult home-gym strength work
+ Single dial swap, ~3 seconds between weights
+ Replaces ~17 fixed dumbbell pairs in one footprint
+ Genuinely durable plate stack — the failure point on dial dumbbells is the locking pin, not the plates
+ JHTNA continues sales + warranty post-acquisition

Cons

− Amazon listing is a single dumbbell — a pair means buying two
− Heavy single unit (~95 lb each) is not move-around-the-house friendly
− Wider handle than 552 may feel awkward for smaller hands at light weights
− Plastic plate skins can crack on hard drops — these are not bumpers
− Warranty covers parts only (3 years, per BowFlex)

Weight range: 10-90 lb (single)
Increments: 5 lb
Dimensions: 17.5" L x 9.5" W x 10" H (per unit)
Sold as: Single dumbbell on Amazon (BowFlex.com sells a pair)
Mechanism: Dial-and-pin select
Warranty: 3 years parts (BowFlex)

Common questions

How does the adjustable dumbbell finder work?

It asks you 3 quick questions about how you'll train and your budget, then matches you to the best adjustable dumbbell from our ranked picks. If nothing fits your budget, it shows the closest match and how far over budget it is. It runs instantly in your browser; nothing is stored and there's no sign-up.

Is the recommendation based on real data?

Yes. Every match is scored against our ranked adjustable dumbbells, which combine expert review research, owner feedback, and our proprietary GymScore. We only recommend a adjustable dumbbell we rank.

Why does it show alternatives instead of just one adjustable dumbbell?

Because the right adjustable dumbbell depends on your budget. We show a money-saving pick when one costs less and a step-up when one costs more. If nothing has a current price within your budget, the closest match is labelled with the amount it runs over.
