A Year With Adjustable Dumbbells

Bowflex SelectTech 552s have been our fitness editor's primary home gym for twelve months. The case for them — and against them — is clearer than expected.

If you have a rack of fixed dumbbells, you don't need this review.

If you have an apartment, a corner, or a guest room you are pretending is a gym, you probably do.

We first published this piece in March 2025 and have revisited the recommendation through 2026-04-18. What follows reflects what survived that review window — the observations we still stand behind, the caveats worth knowing before purchase, and the small ways the piece has aged in ordinary use.

The summary

Adjustable dumbbells solve a real problem — floor space — and create a smaller one: a less honest grip than a fixed dumbbell. After a year of use, the trade is still worth it for most home gyms.

In its favour

  • Replaces fifteen pairs of dumbbells in the footprint of one.
  • Selector mechanism remains tight after a year of regular use.
  • Range covers the majority of home programmes.

Where it falls short

  • Bulky shape changes how heavier sets feel in the hand.
  • Not appropriate for explosive movements or for dropping.
  • Cradle requires a flat, stable surface.

Who it's for

  • — Apartment and home gym setups with limited floor space.
  • — General strength programmes up to roughly 50 lb per hand.

Who should skip it

  • — You train explosive lifts that require dropping the weight.
  • — You want the cleanest possible grip experience above all.

Buying guidance

  • The cradle is taller than photos suggest. Measure before ordering.
  • Pair with a thick mat; the cradle is loud on a hard floor.
  • Plan for the trade-off most new owners only notice in the second month: bulky shape changes how heavier sets feel in the hand. It is workable, but it is easier to design around at the point of purchase than to discover afterwards.
  • Take the second caveat above seriously when comparing across price tiers — not appropriate for explosive movements or for dropping. The cheaper alternatives in the category usually share the same limitation, so paying more rarely solves it.
  • Buy where the piece can be repaired or replaced part-by-part rather than discarded whole. The version we keep recommending is the one we would re-purchase today on its merits, not the cheapest unit that met the spec sheet.

Alternatives we considered

  • PowerBlock Elite EXP

    Squarer shape; some lifters prefer the feel, others do not.

  • Nüobell 80 lb Adjustable Dumbbells

    Rounder, more dumbbell-shaped. More expensive.

Reader questions

Will the selector fail over time?
Not yet, after a year of regular use. The most common failure mode online is debris in the mechanism — keep them clean.
Can I do every dumbbell exercise with these?
Most. The bulky shape can interfere with very close grips and chest-supported variations.
How does Bowflex SelectTech 552 Adjustable Dumbbells (pair) hold up over time?
A full year of ownership has produced no failures we would consider disqualifying. The wear patterns are visible — that is true of anything used daily — but the piece continues to do the work we bought it for. We last revisited the recommendation on 2026-04-18, and the verdict held.
What maintenance does it actually need?
Most of the upkeep is preventative rather than corrective. Follow the manufacturer's care notes for the first six months; after that, the routine you settle into matters more than the one printed on the box. The "Where it falls short" column above flags the specific points worth being attentive to.

Editorial verdict

If you have the floor space for a full dumbbell rack, get a full dumbbell rack. If you don't, this is the most defensible compromise we have tested.
