BowFlex SelectTech 552 Review (2027): Still the Default, With Known Limits
Full research review of the BowFlex SelectTech 552: dial mechanism, increment pattern, size and tray footprint, ownership themes, and the ceiling question.
BowFlex SelectTech 552 Adjustable Dumbbell
The dial dumbbell most home gyms start with, 5 to 52.5 lb in one tray.
- 5-52.5 lb per dumbbell, 15 settings
- Weight range
- 2.5 lb steps from 5 to 25 lb, then 5 lb steps to 52.5 lb
- Increments
- Dial at each end, storage tray required for changes
- Mechanism
Our verdict
The 552 stays at the top of this category because its compromises are the ones most home lifters can live with. The dial is fast and teachable, the 2.5 lb steps below 25 lb are genuinely useful for arms, shoulders, and rehabilitation style progressions, and the round profile behaves like a dumbbell in the hand. Its limits are equally plain: 52.5 lb is the end of the road, the plastic in the selector path makes dropping a real risk rather than a style choice, and at nearly 17 inches long it is one of the widest tools in its class. Buy it as a complete answer for general training, not as the first stage of a heavy system.
What we like
- Dial change is the fastest to learn in the category, with the selected weight printed at each end
- 2.5 lb steps from 5 to 25 lb suit small-muscle progression better than 5 lb jumps
- Round profile and knurled steel handle feel like a normal dumbbell in the hand
What to watch out for
- 52.5 lb ceiling is real; there is no expansion path in the SelectTech dumbbell line
- Plastic dial housing and plate tabs do not tolerate drops onto hard floors
- At 16.9 in long it is a wide dumbbell, which some lifters notice on chest presses
Who it is for
Home lifters training general strength and muscle work up to moderate loads, especially in shared rooms where a tidy tray setup matters.
The dial, and why it won the category
Two dials, one at each end, set into the tray. Turn both to the same number, lift, and the unused plates stay behind. Owners learn it in one session and second users in the house learn it by watching once. The failure mode to respect is partial seating after a rushed change, so the ownership habit is a half-second visual check of both dials before the first rep. That tiny ritual is the entire learning curve.
Increments are the quiet headline
From 5 to 25 lb the 552 moves in 2.5 lb steps: 5, 7.5, 10, 12.5, 15, 17.5, 20, 22.5, 25. Above 25 lb the steps widen to 5 lb. That pattern matches how strength actually grows, fast on big movements and slowly on small ones, and it is the spec most rivals quietly fail to copy. Programs written in round numbers map cleanly onto the low half of this dumbbell.
Size, tray, and room behavior
Each dumbbell measures 16.9 x 8.3 x 9 in in its tray and the pair wants a clear corner about two feet square, or the optional stand. The length is the recurring feel complaint: on close-grip presses the ends approach each other early. On rows, goblet work, and standard presses it disappears from attention within a week for most owners.
Ownership themes after the first year
Long-term praise centers on the routine holding up: dials still clicking positively, trays unmarked, training uninterrupted. The serious complaints cluster tightly around drops and rough set-downs damaging the selector, and around owners who outgrew 52.5 lb faster than expected and faced a full replacement rather than an upgrade. Both are knowable before purchase, which is what this review is for.

FAQ
Questions, answered straight
Is the 552 sold as a pair?
Both ways. The classic listing is a single dumbbell and a pair listing also exists. Check the listing title and the spec table here before ordering; a surprising share of one-star confusion in this category is a single arriving where a pair was expected.
Can the 552 be expanded later?
No. There is no expansion kit in the SelectTech dumbbell line. The upgrade path BowFlex offers is a different dumbbell, the 1090, which is why expected ceiling belongs at the center of the first decision.
