Best Adjustable Dumbbells 2026
Adjustable dumbbells are judged on five things: weight range, how weights change, footprint, price and warranty. Read on 2026-11-07, the makers here run from PowerBlock's Sport 24 at $219 to Ironmaster's 75 lb set at $699, and every maker states some of those five facts and leaves others out.
What "best" means on this page
MudderElla did not test any dumbbell. Every figure below is the maker's own, read from its page on 2026-11-07 and attributed in the sentence. This page ranks nothing. It defines five criteria, puts the stated facts beside them, and says who each option is wrong for, so you can weigh them against your own room and budget. It sits under the wider best home gym guide, which covers machines as well as weights.
The five criteria:
- Weight range: the lightest and heaviest setting per dumbbell, and the step between settings.
- Adjustment: what you do to change weight, and what the maker says about how fast it is.
- Footprint: the size of one dumbbell and whether a stand or rack is needed.
- Price: the price the page shows for the set or pair, with anything extra listed apart.
- Warranty: the length and who it covers.
Two brands could not be read. Nuobell's site would not load in the browser used for this page, and no readable page was found for a budget adjustable set from a third brand. Neither is described here.

The facts side by side
Prices are as each page showed them on 2026-11-07. Bowflex was showing a promotion that ends 11/14, so its prices are written as shown and listed. Where a page gave a pair price per variant, that is the figure used.
| Option | Range per dumbbell | Step | Price shown | Warranty |
|---|---|---|---|---|
| Bowflex SelectTech 552 | 5 to 52.5 lb | 2.5 lb to 25 lb, then 5 lb | Shown at $399, listed at $479 (pair) | Parts 2 years |
| Bowflex SelectTech 1090 | 10 to 90 lb | 5 lb | Shown at $649, listed at $799 (pair) | Parts 3 years |
| PowerBlock Sport 24 | 3 to 24 lb | Not read | $219 | Not read |
| PowerBlock Pro 32 | 4 to 32 lb | Not read | $379 | Not read |
| PowerBlock Pro 50 | 5 to 50 lb | Not read | $549 | Not read |
| PowerBlock Elite USA 90 | 50 to 90 lb | 2.5 to 5 lb | $469 (50 lb), $668 (70 lb), $867 (90 lb) | Not read |
| PowerBlock Pro 100 EXP | 5 to 40 lb, expandable to 100 lb | 2.5 to 5 lb | $539 (40 lb), $758 (60 lb), $977 (80 lb), $1,196 (100 lb) pair | 5-year residential |
| Ironmaster Quick-Lock | 5 to 75 lb | 2.5 lb | $699 (75 lb set), $499 (45 lb set) | Lifetime, home use |
Three notes on the table. PowerBlock's Sport 24, Pro 32 and Pro 50 prices come from its collection and site listing, and the page text read did not give a warranty or step for them. PowerBlock's Pro 100 EXP warranty is stated on its product page; the separate warranty page says it covers defects in materials or workmanship but did not list the years. And Ironmaster's page prices a set of two handles and does not use the word "pair".
Weight range and steps
Bowflex. Bowflex's page lists the 552 at 5 to 52.5 lb per dumbbell with 15 settings and the 1090 at 10 to 90 lb with 17 settings. The 552 page also says that because of manufacturing tolerances, individual settings may vary from their stated weights. Its explore page says you can change weights in 2.5 lb or 5 lb increments.
PowerBlock. PowerBlock's Pro 100 EXP page says you start at 5 to 40 lb and add 20 lb expansion kits, and that each handle includes two 2.5 lb micro weights so weight rises in 2.5 lb to 5 lb steps. Its Elite USA 90 starts at 50 lb and expands to 90 lb, so a lifter who needs light weights would not start there.
Ironmaster. Ironmaster's page says the 75 lb set adjusts from 5 to 75 lb in 2.5 lb increments, with handles that weigh 5 lb empty and locking screws of 2.5 lb each, so a starting weight of 10 lb per dumbbell before plates. A 120 lb add-on kit is listed at $399.
How weights change
Bowflex's page describes dials you twist to a weight setting, and its explore page FAQ says adjustments are "nearly instant". No seconds figure is printed. PowerBlock's page describes a magnetic selector pin that allows quick changes, again without a time. Ironmaster's page says plates change "in just seconds" on the standard set and, for the add-on kit, in under 30 seconds with a quarter to three-quarter turn of the screws. These are the makers' statements, not measurements by this site.
Footprint and stands
Bowflex states 16.9 x 8.3 x 9 in per dumbbell for the 552 and 17.5 x 9.5 x 10 in for the 1090. Bowflex's pages do not print the weight of each dumbbell. Ironmaster states 6.7 in square by 14.5 in long at 75 lb. PowerBlock's dimensions were not read, and PowerBlock's stand shows two prices on its page that were cut off in the read, so no stand price is given for it here.
Stands are separate for most. Bowflex's $199 stand says it is compatible with all SelectTech models, while its $179 stand with a media rack fits the 552 and 1090 but not the 52 or 90. Bowflex's FAQ says a stand is optional but recommended for correct positioning. Ironmaster lists a stand at $169 that holds up to its 120 lb kit.
Who each option is wrong for
- Bowflex 552: wrong for anyone who needs more than 52.5 lb in one hand, or who wants steps of exactly 5 lb throughout.
- Bowflex 1090: wrong for anyone starting below 10 lb per hand, because the lowest setting is 10 lb.
- PowerBlock Sport 24, Pro 32, Pro 50: wrong for a lifter who expects to outgrow 24, 32 or 50 lb, since those ranges are fixed on the pages read.
- PowerBlock Pro 100 EXP: wrong for a buyer who wants the full 100 lb on day one at the lowest outlay, because the page prices each stage as a separate pair price.
- Ironmaster Quick-Lock: wrong for a buyer who wants a dial rather than screws, since the page describes locking screws.
Fixed pairs as the comparison
REP Fitness sells rubber hex dumbbells in pairs, and its page shows, for example, a 25 lb pair at $129.99 and a 50 lb pair at $214.99. REP's page says a rack is not included and lists a rack at $209.99. REP's warranty page says home use is covered for life. Whether adjustables cost less than fixed pairs depends on how many weights you would buy, which is worked through step by step in are adjustable dumbbells worth it.

FAQ
What weight range do adjustable dumbbells cover?
On the pages read on 2026-11-07, the stated maximums per dumbbell run from 24 lb on PowerBlock's Sport 24 to 90 lb on Bowflex's 1090 and PowerBlock's Elite USA 90, and up to 100 lb on PowerBlock's expandable Pro 100 EXP.
Are adjustable dumbbells quiet?
PowerBlock's page says black urethane plates make for a quieter workout, and REP says its rubber coating minimizes noise on fixed hex pairs. No page read gave a decibel figure, and this site did not measure any.
Do I need a stand?
Bowflex's FAQ says its stand is optional but recommended for correct positioning, and Ironmaster says weights can be changed on any flat surface with a stand sold separately. A stand is an added cost, listed in the table of facts above.
What about returns?
Bowflex's return policy page says 30 days from delivery, with return shipping costs of $155 and a processing fee of up to 20%. PowerBlock's refund policy page says returns carry a 20% processing and restocking fee and that you pay return shipping. Ironmaster's page offers a 30 day satisfaction guarantee on most purchases.
