Our Take
The Bowflex SelectTech 1090 is a single adjustable dumbbell replacing 17 individual weights, spanning 10 to 90 lbs (roughly 4.5–40.8 kg) in increments as small as 5 lbs. Aimed at serious home gym users who want a wide training range without stacking an entire rack, it sits firmly at the premium end of the adjustable dumbbell market.
Key Features
Weight range: 10–90 lbs (approx. 4.5–40.8 kg) per dumbbell
Dial-select adjustment system — turn the dial at each end to set your chosen weight
17 weight settings, with 5 lb increments throughout most of the range
Plates lock into the cradle when not in use, keeping loose weights contained
Moulded plastic and metal plate construction rather than traditional cast iron
Requires the dedicated storage tray/cradle for the dial mechanism to function safely
Our Verdict
A strong choice for dedicated home gym users who train across a broad weight range and are short on space. If you train heavy regularly and have the budget, the 1090 justifies its price. Those after lighter weights, tighter budgets, or a more compact option should consider the SelectTech 552 instead.
