A full set of fixed dumbbells eats floor space and money. Fifteen pairs need a rack and a corner of your room. The Bowflex SelectTech 552 promises to replace all of them with one adjustable pair. This Bowflex SelectTech 552 review looks at whether it delivers: how the dial feels in real workouts, where it shines, and where it falls short.
Our score: 4.3/5 — The twist-dial system works and saves serious space. Weight changes take seconds and the range covers most home workouts. The tradeoffs are real: a plastic-heavy build, a 52.5-pound ceiling, and no drop safety. Used buyers: check serial numbers against the June 2025 CPSC recall before training with them.
Bowflex SelectTech 552 Review: What It Is and How It Works
The SelectTech 552 is a pair of adjustable dumbbells. Each handle runs from 5 to 52.5 pounds, and a dial on each end selects the load. Inside each molded cradle sits a set of steel plates; the dial setting decides which plates stay locked to the handle when you lift it out.
The steps run in 2.5-pound increments from 5 up to 25 pounds, then jump in 5-pound steps to 52.5. That spread matters. Most beginners live in the lighter range for months, and the small steps let you add weight gradually instead of leaping from 10 to 15 and wrecking your form. A full fixed-weight rack covering the same range would take up roughly the width of a couch. This takes up the space of two shoeboxes.
In the box: two dumbbells, two storage cradles, a workout guide, and a two-year parts warranty. New purchases also include a two-month JRNY app trial. The plates are steel, with molded plastic around the dial mechanism.
Key Features Worth Knowing
The dial is the headline. One twist sets the weight on both ends of the handle, and you can adjust both dumbbells in well under ten seconds. For supersets and circuits, that speed keeps rest short and your heart rate up.
The storage cradles earn their keep too: each holds the plates you are not using, so the extra iron lives in the tray instead of on your floor — a real win for apartments and spare rooms.
The grip is a tapered hard plastic with a knurled feel — comfortable, though it can get slick with sweaty hands.
The Dial System in Real Life
A normal session goes like this. Set both dials to 20, lift the handles, and the cradles keep the rest of the plates behind. Press, row, set them back. Twist to 35 for the next movement, lift again. It takes seconds, and it never gets old.
The dials need the handle seated fully in the cradle to turn smoothly, and plates can stick slightly on mid-workout changes. A light rattle from the plate stack is normal on some lifts — a reminder that this is a mechanism, not a solid lump of iron.
The drop rule is the big one. These are not drop-safe. Dropping them can crack the shell or knock plates out of alignment. If your style is bailing out of heavy reps and letting weights fall, this is the wrong product. If you set weights down with control, it will never be an issue.
Who It Suits — and Who Should Skip It
The 552 is built for beginners through intermediate lifters training at home. If your heaviest dumbbell work sits in the 30-to-50-pound range for presses, rows, squats, and curls, this covers it.
Small-space training is the other natural fit. Two cradles on a mat take up less room than a nightstand.
Skip it if you press or row past 52.5 pounds per hand — there is no upgrade path — or for CrossFit-style training and Olympic lifts where weights hit the floor. The 552 is about convenience and space, not heirloom durability.

Bowflex SelectTech 552 Review: FAQs
How much weight does each SelectTech 552 dumbbell adjust to?
From 5 to 52.5 pounds per dumbbell. Fifteen settings: 2.5-pound steps up to 25 pounds, then 5-pound steps the rest of the way.
Are the Bowflex 552 dumbbells drop-safe?
No. Dropping them can damage the dial mechanism or knock plates out of alignment. Set them down with control and use the cradles between sets.
Is there a warranty?
Two years on parts, plus a two-month JRNY trial with new purchases.
What about the 2025 recall?
In June 2025, the CPSC issued a voluntary recall for SelectTech 552 and 1090 dumbbells sold between 2004 and May 2025, after reports that plates could dislodge during use. Units sold after the fix are fine. Buying used? Check the serial number on BowFlex’s recall page before training with it.
Final Verdict
The SelectTech 552 earns its popularity honestly. It solves the two problems that keep people out of home strength training: space and hassle. One dial twist replaces a rack of iron, and weight changes take seconds. The plastic-heavy build and the 52.5-pound ceiling are real limits, not dealbreakers for the audience it serves. If you are a beginner or intermediate lifter building a home gym in a normal-sized room, it remains one of the smartest buys in fitness equipment. Our score: 4.3 out of 5.
