The Bowflex SelectTech 1090 single adjustable dumbbell occupies a strange middle ground in the home gym market. It's not the cheapest option, it's not the most premium, and it definitely isn't the most intuitive piece of equipment you'll own. But with 500+ reviews averaging 4.3 stars, plenty of people have decided it works for them—and we need to figure out if you're one of them.
June is prime time for home gym upgrades, and adjustable dumbbells often seem like the obvious solution to storage problems. Before you click that Amazon link, though, let's get real about what this dumbbell actually delivers, who it's genuinely built for, and whether the price tag matches the performance. Some alternatives might serve you better, even if they're less trendy.
"I don't have reliable information about Amanda Brooks' specific views on the Bowflex SelectTech 1090 dumbbells or verified quotes from her. Rather than create a fabricated quote that could be misattributed, I'd recommend reaching out directly to Amanda Brooks through official NASM channels or her verified social media accounts to request an authentic quote about this equipment."
The Bowflex SelectTech 1090 works best as a space-saving compromise, not a revolutionary fitness tool. That 4.3-star rating reflects satisfied customers, but most of them explicitly bought it to avoid storing 15 dumbbells in a studio apartment. If you have room for a standard dumbbell rack and can afford it, buy fixed weights instead—you'll save money and eliminate adjustment time. If space is genuinely your limiting factor and you're willing to spend $300-400 on a single dumbbell, this gets the job done without drama. Just don't buy it expecting miracles or because Instagram influencers claim it's essential.

The SelectTech wins only if you lack storage space or want gradual progression (5-90 lb range in one tool). For side-by-side exercises like chest presses or lateral raises, you'll need two dumbbells anyway, which defeats the space advantage.
Realistically, 2-3 seconds once you understand the dial mechanism. New users often struggle the first 5-10 times, so expect a learning curve. If you're doing high-rep conditioning or drop sets, constant adjustment gets annoying—this is a legitimate workflow friction point that reviews sometimes gloss over.
You can absolutely buy a single unit (which is why the affiliate link shows singular), but many exercises demand two dumbbells. Benching with one dumbbell isn't happening safely. If you only train one limb at a time or do unilateral work exclusively, one is fine; otherwise, plan for two units and double your budget.
