BowFlex SelectTech 552
Fifteen dumbbell settings compressed into one pair—and a strong argument for paying to reclaim floor space.

Each 552 adjusts from 5 to 52.5 pounds across 15 settings. The product is not really about exotic strength equipment; it is about replacing a rack of fixed dumbbells with two compact units.
That compression is useful in a home gym where storage and setup friction matter as much as the exercise itself.
What we know
What does the premium buy?
The rational baseline is fixed dumbbells if space is abundant. SelectTech's premium buys fifteen settings in one footprint and fast changes without a rack. The trade-off is greater mechanical complexity and a 52.5-pound ceiling that stronger lifters can outgrow.
Best for moderate-load home training
The space savings are real and easy to value. Buyers who expect to train well above 50 pounds per hand should choose a higher-ceiling system rather than buy twice.
The catch
Adjustable dumbbells are mechanically more complex than fixed iron. Buyers with abundant space may prefer simpler individual weights; stronger users may outgrow the range.
