NordicTrack Select-A-Weight 55

The NordicTrack Select-A-Weight 55 system uses a digital interface located on a specialized cradle to let you select your desired weight. Once you input the weight, the cradle mechanically adjusts how many plates attach to the handle when you lift it. This allows you to quickly switch between weights ranging from 10 to 55 pounds in 5-pound increments.

While the Bowflex SelectTech 552 allows you to adjust weights in 2.5-pound increments up to 52.5 pounds, the NordicTrack Select-A-Weight adjusts in 5-pound increments up to 55 pounds. NordicTrack utilizes a digital interface and a mechanical cradle, whereas Bowflex uses a manual dial system on the handle itself. Both effectively replace a full rack of traditional dumbbells to save space.

For many casual lifters, 55 pounds per hand is perfectly adequate for isolation exercises like bicep curls, triceps extensions, and lateral raises. However, for advanced lifters performing heavy compound movements like dumbbell bench presses or bent-over rows, 55 pounds will likely be too light. In those cases, users typically need to transition to a traditional adjustable dumbbell system that goes up to 90 or 100 pounds.

Because these adjustable dumbbells house multiple plates within a single unit, they are noticeably longer than standard fixed dumbbells. Even when selecting a lighter weight like 10 pounds, the full length of the dumbbell remains consistent, which can make it feel slightly bulky during certain exercises. The overall length is roughly 16 to 18 inches to accommodate the full stack of weight plates.
