NordicTrack's Select-a-Weight line covers two sizes: a 55 lb-per-hand set with 15 pin-selected weight settings, and a smaller 25 lb-per-hand set with five settings in plain 5 lb steps (NordicTrack).
Weight range and increments
The 55 lb set runs from 10 to 55 lb per hand across 15 settings: 10, 12.5, 15, 20, 22.5, 25, 30, 32.5, 35, 40, 42.5, 45, 50, 52.5 and 55 lb. Each dumbbell head carries two slide-pin selectors — one sets 10 lb jumps, the other fine-tunes in 2.5 or 5 lb steps (NordicTrack). That combination gives you both wide jumps between exercises and small steps for progressive overload, without a dial.
The 25 lb set is simpler: five settings, 5 lb apart, for lifters who don't need to go past 25 lb per hand.
Dimensions and storage
Each 55 lb dumbbell is about 16.5 inches long, and the pair ships with molded storage trays that measure roughly 19.4 x 11.4 x 8.5 inches (Garage Gym Reviews). The 25 lb dumbbells are shorter at about 14.6 inches each. Both sets ship pre-assembled.
Adjustment mechanism: slide pins, not a dial
Where Bowflex uses a single rotating dial and PowerBlock uses a selector pin dropped through a weight stack (see our how do adjustable dumbbells work guide), NordicTrack uses slide-pin selectors mounted on each dumbbell head. You slide each pin to the marking for your target weight, then lift the dumbbell out of its tray — the plates below your setting stay in the tray, and the rest travels with the handle. The 55 lb version needs two pins moved per dumbbell (one for the 10 lb increment, one for the 2.5/5 lb increment) to land on some settings, which is an extra step compared with a single-dial system.
Build
The handle is metal with light knurling, and the plates are flat and round rather than hex-shaped (Garage Gym Reviews). NordicTrack markets the set with a bundled 30-day iFIT trial, which is a subscription add-on and not part of the dumbbell's core hardware or price.

The 55 lb Select-a-Weight set fits a lifter who wants a wide range in one unit and doesn't mind a two-pin selection step instead of a single dial motion. See the NordicTrack Select-a-Weight 55 lb adjustable dumbbell pair listing for current availability. If a single-dial motion matters more than range, compare it against the dial-based options in our best adjustable dumbbells roundup.

Questions people also ask
What weight settings does the NordicTrack 55 lb set have?
It moves through 15 settings per hand: 10, 12.5, 15, 20, 22.5, 25, 30, 32.5, 35, 40, 42.5, 45, 50, 52.5 and 55 lb (NordicTrack). Each dumbbell head has two slide-pin selectors — one for 10 lb jumps, one for 2.5 or 5 lb fine adjustments.
Does NordicTrack make a lighter adjustable dumbbell?
Yes. Alongside the 55 lb set, NordicTrack sells a 25 lb version that moves in plain 5 lb steps — 5, 10, 15, 20, 25 lb per hand (NordicTrack) — a better fit if you don't need to load past 25 lb per hand and want a smaller dumbbell to start.
How does NordicTrack's adjustment mechanism compare to a dial system?
NordicTrack uses slide-pin selectors on each dumbbell head instead of a single dial. You set two pins per dumbbell to land on your target weight, rather than turning one collar to a numbered stop (NordicTrack, Garage Gym Reviews). It's a different motion than the Bowflex SelectTech dial covered in our how-do-adjustable-dumbbells-work guide, though both lock the plates in place once you lift the dumbbell out of its tray.
