Bowflex 552 vs 1090i: which adjustable dumbbell is worth your money?

Range and training potential

Product A, the Bowflex SelectTech 552, adjusts from 2 to 24 kg per dumbbell, which is enough for most home gym users doing presses, rows, lateral raises, curls and even many lower-body accessory movements. Product B, the 1090i, goes much heavier, topping out at 41 kg per dumbbell, so it is the clear winner if you want a single adjustable pair that can carry you further into serious strength training. For progressive overload on compound dumbbell work, the 1090i wins because its ceiling is dramatically higher.

Build quality and design

Both are classic Bowflex selectorised dumbbells with a cradle-based adjustment system, which keeps the footprint small and avoids a full rack of fixed dumbbells. The 552 is the more established design and, judging by the huge review count, has proven itself as a durable home-gym staple. The 1090i feels like the heavier-duty option on paper because it is built to support much more load, but it also has a bulkier form factor and is more expensive to live with. For most users, the 552 wins on practicality and proven day-to-day usability, while the 1090i wins only if you specifically need the extra mass.

Adjustment experience and user-friendliness

The 552 is the easier dumbbell to recommend for beginners and general home training because its weight jumps are manageable and the whole system is simple to learn. The 1090i uses the same broad concept but with a larger weight range, which makes it more versatile for advanced lifters but also less elegant for lighter isolation work. If you want a dumbbell you can grab quickly for mixed training sessions, the 552 wins for simplicity. If you want one pair to cover both moderate and heavy pressing work, the 1090i wins.

Space efficiency

Both products are far more space-efficient than buying a full dumbbell set, and either one suits a garage gym, spare room or apartment setup. The 552 is the better fit for smaller spaces because it is easier to justify at its price and still covers the majority of home workouts. The 1090i takes the win only if you have the room and the training need for heavier loads, but in compact home-gym terms the 552 is the more sensible space-to-performance choice.

Price and value for money

This is where Product A dominates. At £168.99, the 552 is £131.01 cheaper than the 1090i, and that is a massive premium for the extra top-end capacity. The 552 also has far more social proof, with 9,612 reviews and a 4.7/5 rating, compared with the 1090i’s 385 reviews and 4.6/5. In value terms, the 552 wins decisively because it gives most home lifters nearly all the dumbbell they will ever need for far less money.

Overall user experience

For the average home gym buyer, the 552 is the better experience because it offers enough weight for a broad range of training, a lower buy-in cost, and a huge track record of satisfied users. The 1090i is the specialist choice: better if you are already strong, want to keep progressing on heavy dumbbell lifts, and dislike the idea of outgrowing your equipment. But for most people, the extra £131.01 is hard to defend unless you know you will regularly use the higher end of the range.

Overall summary: the Bowflex SelectTech 552 is the smarter buy for most people. The 1090i is the stronger product in terms of maximum load, but the 552 wins on value, popularity, and all-round home-gym practicality. Unless you specifically need 41 kg dumbbells, buy the 552 and put the savings toward a bench, rack, or plates.
