Best BudgetRank #7 in Adjustable Dumbbells
Amazon Basics Adjustable Dumbbell Set (38 lb)
by Amazon Basics
Score
The screw-collar entry point: two 3 lb handles, eight cast-iron plates and threaded collars in a carry case. Nothing about it is fast to change, but it is the cheapest honest way to own real adjustable weight. Treat it as a starter or an accessory-work pair, not a set you will still be loading at intermediate strength.
- A first pair of adjustable dumbbells for accessory work, rehab or a small apartment, where the alternative is no dumbbells at all.
- You already press more than 35 lb per hand, or you want a selectorized dial you can change between sets — buy one of the ranks above instead.
Strengths
- ↑Cast-iron plates and threaded collars, not plastic-shelled concrete
- ↑Ships and sells through the retailer directly, with a hard case included
- ↑Plates are standard 1-inch, so they load onto other spin-lock handles
- ↑Rating volume is unusually deep for this price band
Weaknesses
- ↓38 lb total across the pair caps out fast for pressing and rowing
- ↓Threaded collars make every weight change a manual, two-minute job
- ↓No 1.25 lb plates, so the smallest jump per hand is 2.5 lb
Buyer sentiment
Based on 25 user mentionsBuyers praise the cast-iron plates and the included case. Some flag that 38 lb across the pair is outgrown quickly and that collar changes are slow.

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.
10-90 lb adjustable single dumbbell — the widest range in the consumer-tier dial category. Same dial mechanism as the 552 but heavier internals and a larger handle. The Amazon listing is a single dumbbell (BowFlex.com sells the 1090 as a pair); JHTNA still ships them under the Bowflex name post-Chapter-11.
The premium pick. All-metal construction, compact like a real dumbbell, twist-and-lift adjustment in 1 second. Feels like training, not operating a machine.
The default answer since 2001. 5-52.5 lb range in 2.5 lb increments, dial-adjust mechanism that's been refined for 20+ years. Not sexy — reliable. The Amazon listing sells a single dumbbell, so a pair means buying two.
Solid mid-range dial-adjust dumbbell, sold as a single. The linked version adjusts from 11 to 66 lb in 12 steps of 5 lb, with a double safety lock and an anti-slip steel handle, and is sold by ATIVAFIT itself. Other weight ranges are listed separately. Better build than budget competitors at a fair price.
