Premium PickRank #2 in Adjustable Dumbbells
Bowflex Results Series 1090
by Bowflex
Score
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.
- Lifters needing 70+ lb working weights
- Owners with limited floor space
- You drop dumbbells regularly (plastic plates crack)
- You need a true pair for under ~$1,000
Strengths
- ↑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
Weaknesses
- ↓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)
Verdict: Heavy-lifter's space-saver — one dial swaps 10 to 90 lb, replacing a whole rack.
Specs that matter
| Spec | Value |
|---|---|
| Weight range | 10–90 lb each |
| Increments | 5 lb |

What you get
- Big top end — 90 lb covers most pressing and rows.
- Fast swaps between sets with a turn of the dials.
- Huge space savings vs a fixed dumbbell rack.
What you give up
- Bulky shape — long handle-to-plate length feels awkward at light loads.
- Drop-sensitive plastic housing; don't slam them down.
Buy it if you want serious load without a rack. Skip it if you train explosively or drop weights — get fixed or coated dumbbells.
5 lb jumps can be coarse for small muscle work. More detail at Garage Gym Reviews.

Ranked alternatives from the same category, with our score and the current price.
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.
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. Sold by a third-party seller at or under the maker's price (checked 2026-10-21); the link opens on the 5-80 lb pair.
The Results Series 552 is BowFlex's 2025 redesign of the dial dumbbell that defined the category; the original SelectTech 552 and 1090 were recalled in June 2025 (CPSC; plates could come loose from the handle) and these were the replacement. 5-52.5 lb in 2.5 lb steps above 10 lb, dial-adjust, sold by Amazon. The listing sells a single dumbbell, so a pair means buying two. Only 32 ratings so far on the relaunched listing — thin, re-checked next pass.
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. Checked 2026-10-21: the link opens on the Single, 66LBS-Red option, which is the 11-66 lb dumbbell this review describes, even though the listing's headline names the whole 5-88 lb range.
The Bowflex 552 alternative with a tighter handle and shorter overall length. 5-50 lb in 5 lb increments, twist-handle selection. Core Home Fitness lists each dumbbell at 14.5 inches long at 50 lb, which suits taller lifters and close-grip work.
