The BowFlex SelectTech 552 is the best Bowflex adjustable dumbbell set for most home gyms: it covers 5–52.5 pounds per dumbbell in a compact tray, while the SelectTech 1090 is the better choice if you need heavier loads and have room for larger, heavier units. Choose the 552 for general strength training and tight spaces; choose the 1090 when its 10–90-pound range matches your lifting plans and you can handle its size.
Both models use a dial-based selector, so changing weight is faster than loading plates onto traditional spin-lock dumbbells. That convenience comes with a trade-off: the dumbbells need to sit correctly in their trays for adjustments, and their selector assemblies call for more careful handling than a solid one-piece dumbbell. The right choice depends not just on the top weight, but on floor space, grip preference, and how you train.

BowFlex 552 vs. 1090: the practical differences
| Feature | SelectTech 552 | SelectTech 1090 |
|---|---|---|
| Weight per dumbbell | 5–52.5 lb | 10–90 lb |
| Adjustment increments | 2.5 lb through 25 lb; then 5 lb | 5 lb increments |
| Adjustment mechanism | Dial selector at both ends | Dial selector at both ends |
| Approximate length at maximum weight | About 16.9 in | About 17.5 in |
| Approximate weight of one dumbbell | 52.5 lb at maximum setting | 90 lb at maximum setting |
| Best fit | General training and smaller workout areas | Heavier lifting and users who have more storage space |
Dimensions and increments can vary slightly by product version, so check the current product listing before buying. These are single-dumbbell ranges: a pair of 552s provides two dumbbells that each adjust up to 52.5 pounds, not one 105-pound dumbbell.
Which weight range suits your training?
Choose the 552 for varied workouts and limited space
The 552’s lower starting weight and smaller increments are useful for lighter accessory work, gradual progression, and exercises where a small weight jump makes a noticeable difference. It is a strong match for home routines that mix presses, rows, curls, lunges, and shoulder exercises. Its 52.5-pound ceiling may be limiting, however, for stronger lifters doing heavy rows, presses, or lower-body movements.
Choose the 1090 when you will use the extra load
The 1090 reaches 90 pounds per dumbbell, giving experienced lifters more room to progress. Its 5-pound steps are less fine-grained than the 552’s lighter increments, and its 10-pound minimum can be too heavy for rehabilitation-style work or some isolation exercises. Buying extra capacity only pays off if your exercises and current strength levels make it useful.
A quick capacity check: write down the heaviest weight you use now for your main dumbbell exercises, then estimate a reasonable progression target. If your heaviest working set is 45 pounds and you expect to progress to around 60, the 552’s ceiling will arrive soon. If your target stays below 52.5 pounds, the 1090’s extra weight may add cost and storage bulk without improving your routine.
Adjustment mechanism, grip, and handling
To change weight, return the dumbbell to its tray, turn the selector dials to the desired setting, and lift it only after the plates are seated correctly. The tray-based system makes set changes quick, but it is less forgiving than a fixed dumbbell: do not force a dial that will not turn, lift a partially seated dumbbell, or drop the unit. Misalignment or rough handling can damage the selector or plates.
The 552’s handle has a contoured, rubberized feel; the 1090 uses a textured metal handle. Grip comfort is personal, and the heavier 1090 can feel demanding during high-repetition sets. If your hands are small, you prefer softer contact, or you plan long sets of curls and raises, the 552 may feel friendlier. If you need heavier loads, the 1090’s grip is a reasonable trade-off to consider before purchase.
Both models are longer than a fixed dumbbell at lighter settings because the handle remains between the selected plates. That extra length can affect close-grip exercises, overhead movements, and work performed beside a bench or wall. Leave enough clearance for the dumbbell ends to move freely rather than judging fit by the handle length alone.
Storage and floor-space planning
The included trays keep the dumbbells together and make weight selection easier, but they need a stable, level surface. Measure the space where the trays will sit, then allow room to lift each dumbbell out without scraping a wall or striking a bench. A compact footprint does not mean the units can be tucked into an awkward corner: you need clear access from above and enough room to return them carefully.
| Your home-gym situation | Better fit | Why |
|---|---|---|
| Apartment workout area; mostly general strength work | SelectTech 552 | Lower minimum and finer light-weight increments suit a wider mix of exercises. |
| Experienced lifter whose dumbbell work is approaching 50 lb | SelectTech 1090 | Its higher ceiling reduces the chance of outgrowing the set quickly. |
| Small hands or frequent light accessory sets | Usually SelectTech 552 | Its lighter starting point and softer-feeling handle may be more comfortable. |
| Shared room with limited clear floor area | Either, after measuring | Tray placement and lifting clearance matter more than the weight range alone. |
| Workouts involving frequent drops or rough handling | Neither is ideal | Selector-based adjustable dumbbells should be set down carefully, not dropped. |
Durability: what to expect and how to protect the set
BowFlex adjustable dumbbells combine metal weights with plastic selector components and trays. They can work well for controlled home training, but they are not a substitute for commercial dumbbells in a gym where equipment is repeatedly dropped. Keep the trays on a firm, even surface, use the selector only while the dumbbell is seated, and return each weight to its tray rather than leaving it on an edge or uneven floor.
Before buying, check the current warranty terms and what they cover, since coverage can depend on the model and market. Also inspect the selector operation and plate seating when the set is new. If a dial binds or a plate does not lock in as expected, stop using that dumbbell and consult the manufacturer’s support guidance instead of forcing the mechanism.
Buying decision
For most people comparing the best BowFlex adjustable dumbbells, the 552 is the sensible starting point: it offers a broad range for everyday training, lighter starting weights, and more flexibility for small weight increases. The 1090 is the stronger pick for lifters who know they need loads above 52.5 pounds per hand and have a suitable place to store and use it.
Choose based on your next few years of training, not just the highest number on the dial. Confirm the minimum weight and increments work for your exercises, measure tray placement and lifting clearance, and be realistic about whether you can handle the dumbbells without dropping them. If you need equipment for high-impact use, frequent drops, or shared commercial-style training, consider fixed dumbbells or a more drop-tolerant adjustable system instead.
