Buy the BowFlex 552: it starts at 5 lb, tops out at 52.5 lb, and covers the light end of that range finely enough that you are not forced into 10 lb jumps — which is the whole reason to buy adjustable rather than fixed. Buy the ATIVAFIT if you are certain 25 lb a hand is enough for a long time and the price gap matters. Buy the BalanceFrom hex set if you would rather own five pairs of iron with no mechanism at all. And read the section on increments before you buy anything, because that is where most people get this purchase wrong.
What this query is really asking
We are not going to tell you what women lift. Plenty of women press more than plenty of men, and a dumbbell does not know who is holding it. What the search actually means, in nearly every case, is one of three practical things:
- The range should start light. A set that begins at 15 lb is useless for lateral raises, external rotations and the first month of pressing. Four of the five sets here start at 5 lb, and the one that does not is ranked last for it.
- The steps should be small. Going from 10 lb to 20 lb is a 100 percent jump. For anyone whose pressing numbers are in that range, that jump is the difference between a set of eight and a set of zero. The increment matters more than the ceiling.
- The handle should fit the hand. Thick, long handles are tiring to hold and hard to control at light weights. The listings here publish grip texture but not handle diameter, and we say so rather than invent one.
Those criteria are the ranking. Ceiling comes after them — most buyers searching this phrase are a long way from 50 lb a hand, and paying for headroom you will not use is the most common way money gets wasted on adjustables, as our main adjustable dumbbell roundup also argues.
The five, on range and increment
| Set | Range per hand | Steps | How you change weight | Sold as |
|---|
| BowFlex 552 | 5 to 52.5 lb | Replaces 15 separate weights across the range | Dial at each end | Pair |
| ATIVAFIT | 5 to 25 lb | 5, 10, 15, 20, 25 lb | Dial | Pair |
| BalanceFrom hex set | 5 to 25 lb | 5, 10, 15, 20, 25 lb pairs | Pick up a different pair | 5 pairs + A-frame rack |
| Signature hex set | 5 to 15 lb | 5, 10, 15 lb pairs | Pick up a different pair | 3 pairs |
| FLYBIRD DB2 | 15 to 55 lb | 15, 25, 35, 45, 55 lb | One-handed lever on the base | Pair |
Ranges and steps are quoted from each manufacturer listing read on 2026-09-18. The BowFlex listing states the 5 to 52.5 lb range and that the set replaces 15 separate weights; the individual increments are not itemized on the listing, so the table says what the listing says.
Why the BowFlex wins, and why the FLYBIRD is last
The BowFlex wins on the criterion that matters most here: fifteen weights between 5 and 52.5 lb means the light end is covered in small steps, and the range keeps going. A buyer who starts at 8 lb lateral raises and 15 lb presses will not outgrow it for years, and the set is so widely owned that trays and dials are easy to source when something eventually cracks — a real advantage on a mechanism-based product, covered in how long adjustable dumbbells last.
The FLYBIRD DB2 is a well-built set with a genuinely quick one-handed change, and it is last on this page for one reason: its steps are 10 lb, and its range starts at 15. For a 55 lb goblet squat that is fine. For pressing at 15 to 25 lb, a 10 lb jump is too coarse to progress on, and there is no 5 or 10 lb setting for the small shoulder work most people need. On the budget adjustable page it ranks well; on this page the increment rule puts it at the bottom.
The ATIVAFIT sits between them. Five steps from 5 to 25 lb in 5 lb increments is exactly the light-end coverage the query wants, at a fraction of the BowFlex's price. Its ceiling is the limit: 25 lb a hand is a set most consistent lifters outgrow on rows within a year or two, and the set cannot be extended. Buy it knowing that.
The case for owning no mechanism
The two hex sets are on an adjustable page on purpose. Five pairs of rubber-coated cast iron with a rack cover the same 5 to 25 lb range as the ATIVAFIT, in the same 5 lb steps, with nothing to select, nothing to seat in a cradle and nothing that cracks when set down hard. They take more floor space and they cost more per pound of range at the top end. They also last forever, which on this site counts for a great deal — the argument is made in full in adjustable vs fixed dumbbells and the wider fixed field is ranked in the best hex dumbbells.
The Signature 5, 10 and 15 lb set is the smallest sensible starting point: three pairs for accessory work, bought once, expanded later by adding single pairs. If the honest answer to "how heavy will I go" is "not very, for a while", it is the cheapest correct purchase on the page.
What fails, and what to do about it
Every adjustable here fails the same way: the plates are permanent, the selector is the product, and the selector is damaged by being forced when the dumbbell is not seated or by being dropped. Light weights do not exempt you — a 10 lb setting dropped onto a cradle cracks the cradle just as surely. The hex sets cannot fail this way; their only wear is the rubber coating, which chips if they are banged together.
Whatever you buy, put a mat under it. The flooring roundup has a rubber-top tile set that costs less than a replacement cradle.
How to choose
Write down three weights, not one
The weight you would use for a lateral raise, for a row, and for a goblet squat. Those three numbers tell you the range you need today. If the lightest is under 10 lb and the heaviest is under 25, the ATIVAFIT or a hex set is enough; if the row number is already 20 lb and rising, buy the BowFlex and skip the second purchase.
Count the steps between your numbers
If two of your three weights are within 5 lb of each other, you need a set with 5 lb or finer steps in that zone. This single check rules the FLYBIRD out for most people who search this phrase, and rules the BowFlex in.
Decide where it lives
A dial set needs its tray on the floor and a permanent spot. A hex set needs a rack and about the floor area of a doormat. Neither belongs on a shelf; a set that has to be fetched is a set that does not get used.
Add a bench before adding weight
Pressing and rowing with dumbbells need a bench far more than they need a heavier set. The adjustable bench roundup has options that fold to the width of a hallway.
