About eighteen months into training seriously at home, I reached for my heaviest adjustable dumbbell, dialed it to the top of its range, and pressed it for a set of flat dumbbell presses. The bar moved for twelve clean reps when it should have been a grind at eight. I wasn’t out of strength. I was out of dumbbell. That’s a strange, slightly deflating moment — realizing the tool you bought to last you for years has a ceiling, and you’ve just put your head through it. My options were to keep doing higher-rep sets I didn’t want to do, start buying fixed dumbbells in 5-pound jumps and surrender the floor space I’d carefully protected, or replace the whole set with something that went heavier.
That last option is what the Bowflex SelectTech 1090 exists to solve. Where the more famous 552 tops out at 52.5 pounds per hand, the 1090 starts at 10 and climbs all the way to 90, which is enough load for most people to press, row, lunge, and Romanian-deadlift for the rest of their lifting lives. It is not the dumbbell most home gyms should buy first. But for the specific person who has genuinely run out of a lighter set — or who knows on day one that they will — it answers a question almost nothing else on the market answers without devouring a wall of your gym.
This review works through what the 1090 actually is, where it’s strong, where it quietly frustrates owners, and who should buy it instead of the obvious cheaper alternative. I’ve owned and trained with adjustable dumbbells in a home gym for years, and I’ve read through a large pile of verified owner reviews to separate the things that hold up from the things people regret. The short version: the 1090 is the right tool for a narrow, real group of lifters, and the wrong tool for everyone else.

How to judge a heavy adjustable dumbbell
Before getting to the 1090 specifically, it’s worth being honest about what actually matters once you’re shopping at the heavy end of this category, because the priorities shift compared with a light starter set.
The first and most obvious factor is top-end weight, and it’s the entire reason a set like this exists. A 5-to-52.5 set covers the overwhelming majority of pressing and rowing work for most lifters, but a handful of movements — flat and incline dumbbell press, heavy rows, goblet and split squats, Romanian deadlifts — will outrun 52.5 pounds for anyone who’s been training consistently for a year or two. If you’ve already hit that wall, no amount of clever design on a lighter dumbbell fixes it. You need more iron in your hand, full stop.
The second factor is increment size, and this is where heavy adjustables make a real trade-off that buyers routinely overlook. Going up to 90 pounds usually means the jumps between settings get coarser. Five pounds between settings is fine for a heavy press or row, but it’s a blunt instrument for small-muscle work like lateral raises or rear-delt flyes, where a 50% jump from one setting to the next is the difference between good reps and no reps. A great heavy dumbbell still can’t give you the fine control of a dedicated light pair, and you should know that going in.
Third is the adjustment mechanism and how it fails. Every dial-style adjustable dumbbell shares the same vulnerability: the plates you don’t select stay behind in a cradle, and the handle has to seat perfectly to pick up or drop the right plates. A good mechanism does this crisply and locks with no rattle. A mediocre one leaves plates behind, jams, or develops play over time. At heavier loads the consequences of a half-seated handle are more serious, so the locking system matters more here than it does on a 25-pound dumbbell.
Fourth is build material and what it implies about durability. Older adjustable dumbbells leaned heavily on molded plastic housings, which is fine until the day one gets dropped or knocked off a bench. Newer designs reinforce the high-stress parts with metal. None of these are built to be dropped from lockout the way a rubber hex or a loadable handle is, and treating them that way will break them regardless of brand.
Finally there’s footprint, ergonomics, and total cost. The appeal of any adjustable is replacing a rack of fixed dumbbells with one pair, but a heavy adjustable is a physically large object, and the handle length and shape determine whether certain exercises feel natural or awkward. Then there’s the price, which at this end of the category climbs to a point where it’s worth asking whether you’d be better served by a loadable handle and plates you may already own.
The Bowflex SelectTech 1090, by the numbers
Here’s what the 1090 actually delivers, drawn from Bowflex’s current product specifications.
Each dumbbell adjusts from 10 to 90 pounds in 5-pound increments, giving you 17 weight settings per hand: 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, and 90 pounds. Bowflex’s pitch is that the pair replaces up to 17 sets of fixed dumbbells, and the math is honest — that really is the equivalent rack you’d otherwise be storing. The set is sold as a pair, and storage trays are included so the plates you aren’t using have somewhere to live instead of scattering across the floor.
You change weight with a selection dial on each end of the handle: dock the dumbbell in its tray, twist to your target number, and lift out only the plates you’ve selected. Bowflex builds the current Results Series version with reinforced metal components and a secure locking system, a meaningful update from the all-plastic reputation that earlier SelectTech models carried, plus knurled hand grips for control when the load gets heavy and your hands get sweaty. Each dumbbell measures 17.5 inches long by 9.5 inches wide by 10 inches tall, which is the detail most people don’t think about until the dumbbell is in their hand.
Coverage on the back end is a 3-year parts warranty, which is reasonable for the category though not generous. The unit pairs with a free Bowflex SelectTech app for guided workouts, and it’s compatible with Bowflex’s separately sold adjustable dumbbell stand if you’d rather lift the weights from waist height than off the floor. At list price the 1090 sits around $799, though it’s frequently discounted closer to $600–$699, and availability on the official site comes and goes — at the time of writing it’s often easier to find through major retailers than direct.
What the 1090 gets right
The headline strength is exactly what you’d expect and shouldn’t be undersold: the weight range is the whole point, and it delivers it. Ninety pounds per hand is a genuinely serious load. For the large majority of home lifters who aren’t competitive strength athletes, a pair of these covers heavy dumbbell pressing, heavy rows, walking lunges, split squats, and Romanian deadlifts with room to spare for years of progression. The wall you eventually hit with a 52.5 set simply isn’t there. Owner feedback from people who upgraded specifically for this reason is consistent on the point — the relief of not having to think about a ceiling again is the most common note in positive reviews.
The space savings at this load are dramatic, and they scale with the weight. Replacing a 52.5-pound adjustable is one thing; replacing the equivalent of a 17-rung fixed rack running up to 90 pounds is the difference between a corner of a room and an entire wall of dumbbells plus the rack to hold them. For anyone training in a garage, a spare bedroom, or a basement where every square foot is contested, that consolidation is the strongest argument in the dumbbell’s favor after the weight range itself.
The current build is a real step up from the SelectTech of a decade ago. The reinforced metal components and the locking system address the single biggest historical complaint about this style of dumbbell, and spec analysis backs up the change in materials. The knurled grip is a small thing that matters more than it sounds — at 80 or 90 pounds, a slick handle is a safety problem, and a textured one is reassuring. Owners who’ve moved up from older plastic-handled adjustables tend to single the grip out as an underrated improvement.
Finally, the dial mechanism, when used correctly, is fast. Going from a heavy compound lift to a lighter accessory movement takes seconds, which keeps supersets and circuits flowing in a way that fumbling with spin-lock collars and loose plates never will. For people whose training time is squeezed into tight windows, that speed is a quiet but daily benefit.
Where it frustrates owners
No honest review stops at the highlights, and the 1090 has real limitations that show up repeatedly in owner reports.
The most common one is length. Each dumbbell is 17.5 inches long no matter which weight you’ve dialed, because the full plate stack is always sitting in the handle whether you’re using it or not. At 10 or 15 pounds, you’re holding a dumbbell the size of a 70-pound one, and that makes some movements feel clumsy — narrow exercises, certain curls, anything where a short, compact dumbbell would naturally sit closer to your body. It’s not a dealbreaker, but it’s the thing people most often wish they’d known before buying.
The second is the coarseness of the 5-pound jumps. Unlike the lighter SelectTech, which offers finer 2.5-pound steps at the bottom of its range, the 1090 moves in 5-pound increments the whole way up. For heavy compounds that’s fine. For small-muscle isolation work — lateral raises especially — jumping from 10 to 15 pounds is a 50% increase, and there’s no setting in between. If a lot of your training is shoulder and arm detail work, this is a genuine compromise you’ll feel.
Third, the dial system demands discipline, and owners who don’t give it any are the ones who leave bad reviews. You have to dock the dumbbell fully in its tray and seat the dial completely before lifting, or plates can be left behind or fail to lock. You cannot change weight mid-air or away from the cradle. Most people adapt within a week, but it’s a real behavioral constraint, and it means the trays aren’t optional — they’re part of how the dumbbell works.
Fourth, like every dumbbell of this type, it cannot be dropped. These are precision mechanisms with internal plates and a housing, not bumper-grade tools meant to be slammed down from lockout. If your training style involves dropping heavy dumbbells — some CrossFit and high-intensity work does — this is the wrong category entirely, and you’d be happier with loadable handles or fixed hex dumbbells you can abuse without guilt.
Finally, there’s price and value at the margins. Paying up toward $799 for the convenience of adjustability is easy to justify if it replaces a wall of iron you’d otherwise buy and store. It’s harder to justify if you already own a loadable barbell setup and plates, in which case a pair of loadable dumbbell handles can reach similar loads for a fraction of the price, at the cost of slower weight changes. The 1090 buys you speed and tidiness, not raw capability you couldn’t get cheaper.
How it compares to the alternatives
The most important comparison is against the dumbbell most people actually cross-shop: the lighter 5-to-52.5 SelectTech. If you have never bumped into the 52.5-pound ceiling and you’re not sure you ever will, the lighter set is the smarter buy — it’s cheaper, its 2.5-pound increments at the low end are friendlier for accessory work, and 52.5 pounds per hand is plenty for a very large share of lifters. The 1090 only makes sense if heavier is a need you can name, not a number that simply sounds more impressive. Buying 90 pounds of capability you never use is just paying to store extra plates.
Against premium dial competitors like the NuoBell, the trade-off is feel and shape versus reach and price. The NuoBell’s round profile and shorter length sit closer to a traditional dumbbell in the hand, which a lot of lifters prefer, and it’s covered in detail in our NuoBell adjustable dumbbells review. The Bowflex counters with a longer, more familiar mechanism, wide retail availability, and pricing that’s often more aggressive when it’s on sale. Neither is clearly better; they’re optimized differently.
If your budget is the binding constraint, it’s worth reading our breakdown of the Core Home Fitness adjustable dumbbell, which is the value pick in this category but tops out well below 90 pounds — fine for many, a non-starter for anyone shopping the 1090 for its ceiling. And if you specifically dislike the leave-plates-behind dial design, the quick-lock approach is a different mechanism worth understanding before you commit; our Ironmaster Quick-Lock versus PowerBlock comparison lays out how those systems trade adjustment speed for durability and droppability.
One last pairing note: a heavy dumbbell is only as useful as the surface you press it on. If you’re loading up to 80 or 90 pounds for incline and flat work, a wobbly bench becomes the weak link fast, and it’s worth matching the dumbbell to a sturdy one from our guide to the best adjustable weight benches.
Who should buy the Bowflex SelectTech 1090
The 1090 is an easy recommendation for one specific person: the lifter who has been training consistently for a year or more, has genuinely outgrown a 52.5-pound set or knows from experience they will, and wants to consolidate a heavy dumbbell rack into a single pair without surrendering a wall of their gym. For that person, the weight range, the space savings, and the speed of the dial mechanism line up almost perfectly, and the upgraded metal build addresses the durability worry that used to hang over this style of dumbbell.
It’s the wrong buy for nearly everyone else. If you’re new to training, the lighter SelectTech or a budget set will serve you better and cheaper while you figure out what you actually need. If most of your work is high-detail shoulder and arm training, the 5-pound increments will annoy you. If you drop your dumbbells, you’ll break it. And if you already own loadable handles and plates, you’re paying mostly for convenience you might not value enough to justify the price.
If you fit the narrow profile it’s built for, the SelectTech 1090 is one of the few products that solves the heavy-adjustable problem without taking over the room, and it’s worth checking the current price, since it swings widely between full retail and frequent discounts: View on Amazon. If you don’t fit that profile, the honest move is to spend less on a lighter set and put the difference toward a good bench or rack instead.
Frequently asked questions
Is the Bowflex SelectTech 1090 worth it over the 552?
Only if you need the weight. The 552 (5 to 52.5 pounds) is cheaper, has finer 2.5-pound increments at the low end, and covers most lifters’ pressing and rowing for years. Step up to the 1090 if you’ve actually hit the 52.5-pound ceiling or know you will — not because 90 sounds better on paper. Paying for capability you never use is just buying storage.
Can you drop the SelectTech 1090?
No. Like all dial-style adjustable dumbbells, it’s a precision mechanism with internal plates and a housing, not a bumper-grade tool. Dropping it from lockout risks damaging the plates and the locking system. If your training involves dropping heavy dumbbells, use loadable handles or fixed hex dumbbells instead.
What are the weight increments on the 1090?
Five pounds across the entire range, giving you 17 settings per dumbbell from 10 to 90 pounds. That’s well suited to heavy compound lifts but coarse for small-muscle isolation work, where the jump from one setting to the next can be a large percentage of the load.
How much space does it take up, and does it need the stand?
Each dumbbell is about 17.5 inches long, 9.5 wide, and 10 tall, and the set is sold as a pair with storage trays included. You don’t need the separately sold stand, but you do need to dock each dumbbell in its tray to change weight — the trays are part of how the adjustment works, not just storage.
Do you have to pay for a subscription to use it?
No. The dumbbells function fully on their own. Bowflex offers a free SelectTech app with guided workouts, and there’s a separate paid JRNY membership for adaptive programming, but neither is required to simply use the weights.
What’s the warranty on the Bowflex SelectTech 1090?
Bowflex covers the current Results Series 1090 with a 3-year parts warranty. That’s reasonable for an adjustable dumbbell, though not the longest in the category, so factor it into the value calculation against competitors that offer longer coverage on the mechanism.
