The Bowflex SelectTech 1090i is Bowflex's higher-capacity dial dumbbell line, listed at 10 to 90 lb (4.5 to 40.8 kg) per dumbbell on bowflex.com, but its UK page contradicts itself on range and settings. The indicative price here, around £289 (checked Oct 2026), is for a single dumbbell, not a pair.
This review reads the maker's pages and does not involve testing, because the site does not test products.
What does the maker say the 1090 is?
On bowflex.com, the Results Series 1090 is described as a pair of dial-adjustable dumbbells with a curved shape, tapered plates, knurled hand grips and a secure locking mechanism, replacing 17 sets of weights. Storage trays are listed and a stand is sold separately. Bowflex's UK page for the 1090i pair uses the same 17-set description and says the dumbbells are compatible with the JRNY app, which is a separate membership. The bowflex.com page also lists a Results Series 90 with the same 10 to 90 lb range, described as a traditional dumbbell shape with uniform plates.

The bowflex.com page is for the Results Series 1090 and the UK page for the 1090i, so they are related but not identical listings.
What range does the Bowflex 1090i cover?
The bowflex.com 1090 page lists 10 to 90 lb, or 4.5 to 40.8 kg, per dumbbell in 17 settings, and the UK 1090i description says 4 to 41 kg. The UK specification table conflicts with this, so confirm the range with the seller before ordering.
Why does the UK 1090i page conflict with itself?
Its description says 17 settings and 4 to 41 kg, but its specification table shows 15 settings topping out at 23.9 kg, which matches the 552 rather than the 1090. The two cannot both be right for the same product. The UK page also gives dimensions in both inches and a second set labelled cm that match the bowflex.com 1090 size. Because the bowflex.com 1090 page shows 17 settings to 40.8 kg, this review treats the 1090 figures as the higher-range specification, but the UK listing is what a UK buyer is purchasing, so ask the seller to confirm. The UK page also showed the product as sold out at the time it was opened, with an add to cart button still displayed.
Is the price for a pair of 1090i dumbbells?
No. The indicative price in our data, around £289 (checked Oct 2026), is for a single dumbbell, so a pair needs two and costs more. The maker pages describe the 1090 as sold as a pair, and the UK page shows more than one price block. Confirm the price and quantity with the retailer before ordering, and do not compare the £289 figure directly with the pair prices of other sets.
Who does the specification suit?
A 4.5 kg bottom setting and a 40.8 kg top setting suit buyers who expect to use heavier loads than the 552 or the PowerBlock allow. This is reasoning from the figures, not from use. The lowest setting is above the lightest settings of those two sets, so it is a weaker match for someone who wants a very light starting weight. See the Bowflex 552 review and PowerBlock Sport 24 review for those ranges.
Is the 1090i a good choice for beginners?
Its lowest setting is 4.5 kg per dumbbell on the bowflex.com page, which is heavier than the lightest settings of the 552 (2.3 kg) or the PowerBlock Sport 24 (about 1.4 kg). It suits buyers who expect heavy loads. The NHS strength exercises page suggests starting with light weights, such as filled water bottles, and progressing gradually, and personal advice on loads should come from a qualified professional.
How big is each Bowflex 1090 dumbbell?
Bowflex lists 44.4 x 24.2 x 25.3 cm (17.5 x 9.5 x 10 in) per dumbbell. Each dumbbell is 44.4 cm long and about 25 cm tall, and Bowflex lists a stand as a separate purchase. At the top setting each dumbbell is a heavy object, so give it a clear route and a firm surface. See flooring for heavy weights and home gym safety tips.
How does it compare with the 552?
On the maker figures, the 1090 line has 17 settings in 5 lb steps from 10 to 90 lb, while the 552 has 15 settings from 5 to 52.5 lb with finer 2.5 lb steps at the light end. Each 1090 dumbbell is larger: 44.4 x 24.2 x 25.3 cm against 43 x 21.2 x 22.8 cm. The 1090's lower bound is 4.5 kg per dumbbell against 2.3 kg for the 552, and its upper bound is 40.8 kg against 23.9 kg. Bowflex lists a longer parts warranty for the 1090 on bowflex.com (3 years against 2), but the UK page lists 2 years, so confirm with the seller.

What warranty does the 1090i have?
The UK 1090i page lists 2 years on parts and states no labour or frame cover, while the bowflex.com 1090 page lists 3 years on parts. Bowflex also sells Protection+ plans for the 1090 on bowflex.com at an extra cost, covering items such as accidental damage from handling. UK availability is not stated, so check the terms with your seller.
What to check before buying
- Price basis. The indicative price here, around £289 (checked Oct 2026), is for a single dumbbell. A pair needs two, so budget for roughly double and confirm with the retailer.
- Range. Confirm the stated weight range and number of settings on the listing, given the conflict above.
- Warranty. UK page says 2 years on parts, while bowflex.com lists 3 years for the 1090.
- Delivery. The UK page quotes about 28 days from the order confirmation for credit card payments, so check the seller's current delivery terms.
- Returns. The UK page quotes a 7-day cooling-off period with the customer paying return postage, and says defective items are refunded in full including delivery and return costs. GOV.UK business guidance says online customers can cancel up to 14 days after delivery without giving a reason, so the two periods differ; ask the seller which applies to your order.
- Stand. Sold separately.
- Safe use. Bowflex's UK page says to place the dumbbell fully in its base before selecting a weight and to lift the handle only once the weight is fully selected. Ask a qualified professional about heavy loading.
Who should skip the 1090i?
Buyers who want the lightest possible starting load should look at the 552 or the Sport 24. Buyers short on space should weigh the 44.4 cm length per dumbbell. Buyers who want certainty about the product before paying should skip any listing that cannot confirm the weight range, given the conflicting figures. For lower loads and a smaller footprint, see the adjustable dumbbell comparison, and for the fixed-weight route read adjustable vs fixed dumbbells.
