Buy NowThe BowFlex Results Series 1090 SelectTech Dumbbells are adjustable dumbbells that replace up to 17 pairs of fixed-weight dumbbells with a single unit per side, spanning 10 to 90 lb in 5 lb increments via a turning dial. Aimed at home gym users who want heavy compound-lift capacity (bench press, rows, squats) without the floor space a full dumbbell rack requires, the 1090 sits above BowFlex’s lighter 552 SelectTech Dumbbells line and is the heaviest consumer option in the SelectTech family. Each dumbbell measures 17.5” L x 9.5” W x 10” H and uses a knurled metal handle with a secure locking mechanism to hold the metal weight plates in place. Reviewers consistently praise the speed and reliability of the dial adjustment – swapping weights takes seconds – but repeatedly flag the plastic components inside the handle as the weak point: several independent reviewers and r/homegym owners describe them as prone to wearing down or breaking over time, and the dumbbells should not be dropped. At 17.5” long they also run bulkier than a traditional dumbbell, which can affect range of motion on curls and overhead presses. They ship as a pair with storage trays and are compatible with BowFlex’s SelectTech Adjustable Dumbbell Stand, sold separately.

Adjustable dumbbells replace a whole rack of fixed dumbbells with one pair whose weight you change via a dial, pin, or selector plate. They are the space-and-money saver for home gyms: a single set can span roughly 5–50+ lb per hand. The trade-offs are bulkier handles, a fixed max weight, and a mechanism that can wear or rattle.
Fast adjustment (dial or lever beats stacking plates), a wide and useful weight range, a balanced feel that doesn’t clunk mid-rep, and a durable locking mechanism. Many sets include or offer a stand — worth it, since the blocks are awkward to load off the floor.

BowFlex’s Results Series 1090 SelectTech dumbbells replace a full rack of fixed weights with a single adjustable pair spanning 10-90 lb in 5 lb increments, aimed at lifters who want heavy compound-lift capacity without the floor space. Its standout dimension is functionality: the dial-based adjustment mechanism reliably swaps settings in seconds, and reviewers across Garage Gym Reviews, YouTube, and r/homegym consistently credit it as genuinely faster and more convenient than any plate-loaded alternative. Its weakest dimension is build quality/durability – despite a metal knurled handle, multiple independent reviewers and several r/homegym owners describe the internal plastic components (the lips that catch each weight disc) as prone to wear and breakage over time, with more than one owner explicitly steering buyers toward PowerBlock or NÜOBELL instead. The dumbbells also run long (17.5”), which several sources note compromises range of motion on curls and overhead presses, and they cannot be dropped without risking damage.
