A pair that changes from 5 to 50 lb each: set a dumbbell in its cradle, twist the handle with one hand, and lift. The listing gives 14.5 inches long and a soft contoured grip. - **Small weight steps in a compact block:** PowerBlock Elite EXP Adjustable Dumbbells. A magnetic pin picks one of 16 weights from 5 to 50 lb per hand, with 2.5 lb micro weights for small steps. The listing says the block replaces 16 pairs of dumbbells. - **A tray set that reaches 55 lb per dumbbell:** NordicTrack 55 lb Select-a-Weight Dumbbells. A selector set that moves in 2.5, 5 and 10 lb steps up to 55 lb per dumbbell, with a 10 lb handlebar you can also use alone and fitted storage trays. - **Lighter workouts up to 25 lb per dumbbell:** Lifepro Adjustable Dumbbells. A quick-adjust dial changes each dumbbell from 5 to 25 lb, and the listing names alloy steel, a locking mechanism and a textured non-slip grip. - **A plate-and-collar set with a carry case:** Amazon Basics Adjustable Dumbbell Hand Weight Set. Two 3 lb handles, plates of 2.5 and 5 lb and threaded collars make a pair of 38 lb in total, packed in a carry case with a handle. - **More total weight in a plate-and-collar set:** Yaheetech Adjustable Dumbbell Set. A spin-lock set with 16 plates in four weights, threaded bars and star-lock collars, up to 66 lb for the pair, with plates made of polyethylene. Our top pick is the **[Core Home Fitness Adjustable Dumbbell Set](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-1)**. We read 92 Amazon listings for "adjustable dumbbells set", compared 10 contenders on their own pages, and this is the one that suits the most people: set a dumbbell in its cradle, twist the handle with one hand, and it changes anywhere from 5 to 50 lb. It is the easy first pick if you want one set for a home gym. Then one set for each other need. For small weight steps in a compact block, the **[PowerBlock Elite EXP](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-2)**. For a tray set that reaches 55 lb per dumbbell, the **[NordicTrack Select-a-Weight](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-3)**. For lighter workouts, the **[Lifepro](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-4)** stops at 25 lb per dumbbell. For plate-and-collar sets, the **[Amazon Basics](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-5)** set comes with a carry case, and the **[Yaheetech](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-6)** set carries more weight in total. ## How to choose adjustable dumbbells Adjustable dumbbells look alike and work differently. These are the four things that matter, backed by Wirecutter and Live Science, which have both worked through many sets. - **How the weight changes.** Live Science sorts adjustable dumbbells into digital, dial and spin-lock sets. A dial set changes weight with a dial on the dumbbell, usually while it sits in a cradle. A spin-lock set is a bar with plates you load by hand and lock with collars, which Live Science calls more labor intensive but sturdy and long-lasting. Wirecutter adds handle-twist sets and timed changes at 4 to 25 seconds per dumbbell across the sets it tried; its traditional collar set took about 25 seconds at best. Here the [Core Home Fitness](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-1) twists, the [PowerBlock](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-2) uses a pin, the [NordicTrack](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-3) uses a selector, the [Lifepro](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-4) uses a dial, and the [Amazon Basics](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-5) and [Yaheetech](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-6) sets use collars. - **Weight range and step size.** Wirecutter looks for loads from 5 or 10 lb up to 50 lb per dumbbell, which it says is enough for most exercisers. It adds that 2.5 lb steps suit lighter loads, while 5 lb steps can mean fewer reps when you move up. The [PowerBlock](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-2) adds 2.5 lb micro weights, the [NordicTrack](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-3) moves in 2.5, 5 and 10 lb steps, and the [Core Fitness](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-1) set moves in 5 lb steps. - **Length and the cradle.** Some sets get shorter as you take weight off, and others keep the same length. Wirecutter says a long bar can force smaller frames to change how they move, and it measured the [Core Fitness](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-1) set at 14.5 inches fully loaded. Live Science found one set whose plates sat so tight in the dock that it needed a tug and a foot on the tray at higher weights. - **Plastic or metal, and recalls.** Wirecutter looks at how much of a set is plastic and notes that most plated sets risk unselected plates sticking while you pick a load, and then falling. It also reports that BowFlex and the US Consumer Product Safety Commission jointly recalled an earlier SelectTech 552 in June 2025, after more than 300 reports of plates dislodging during use. ## Our picks in detail ### 1. Core Home Fitness Adjustable Dumbbell Set: best one-hand twist set **Why it made the list** - Its listing says each dumbbell changes from 5 to 50 lb with one hand: set it in the cradle, twist the handle, and the weight changes. - It is compact. The listing gives 14.5 inches long, and Wirecutter notes the dumbbell shortens as the weight drops. - The grip is described as contoured, textured and soft, and the listing names a two-year parts warranty. **Drawbacks** - Weight moves in 5 lb steps only, so there is no 2.5 lb jump for light work. - Wirecutter says the cradle sometimes sticks to the dumbbell at 35 lb and always at 50 lb. A hand or a foot on the cradle frees it. **Skip it if** you want 2.5 lb steps. The [PowerBlock](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-2) has micro weights. ### 2. PowerBlock Elite EXP Adjustable Dumbbells: best for small weight steps **Why it made the list** - A magnetic pin picks one of 16 weights from 5 to 50 lb per hand, with 2.5 lb micro weights for the small steps. - Its listing gives 12 by 7 by 7 inches and says it replaces 16 pairs of traditional dumbbells. - Expansion kits take it to 70 or 90 lb per hand as you get stronger, and the listing names a five-year residential warranty. **Drawbacks** - It is a block, not a round dumbbell. Wirecutter says some people are put off by the boxy shape of a [PowerBlock](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-2), which past testers compared to reaching into a toaster. - The expansion kits are sold separately. **Watch for this:** The listing says the Elite EXP kits do not work with the Elite USA 90. Match the family before you buy a kit. **Skip it if** you want to change weight by turning a handle. The [Core Home Fitness](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-1) set does that. ### 3. NordicTrack 55 lb Select-a-Weight Dumbbells: best tray set to 55 lb **Why it made the list** - Its listing says each dumbbell moves in 2.5, 5 and 10 lb steps, picked with a weight selector, up to 55 lb. - Each dumbbell has a 10 lb handlebar that can be used by itself. - Custom-molded storage trays with clear weight markings come with it. **Drawbacks** - Wirecutter says the adjustment takes some getting used to and that the lever on its set occasionally stuck. - The listing names steel and hardened plastic, and Wirecutter pays attention to how much of a set is plastic. **Skip it if** you want one motion to change weight. The [Core Home Fitness](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-1) set needs only a twist. ### 4. Lifepro Adjustable Dumbbells: best for lighter workouts **Why it made the list** - A quick-adjust dial changes each dumbbell from 5 to 25 lb, and the listing says one set replaces several fixed dumbbells. - The listing names alloy steel, a secure locking mechanism and a textured non-slip grip. **Drawbacks** - It stops at 25 lb per dumbbell. - The dumbbell has to sit squarely in the cradle to change weight, and it can feel clunky in use. **Watch for this:** [Lifepro](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-4) sells this line in several sizes under related listings. Check the weight on the page before you buy. **Skip it if** you will lift more than 25 lb per dumbbell. The [Core Home Fitness](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-1) set and the [PowerBlock](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-2) reach 50. ### 5. Amazon Basics Adjustable Dumbbell Hand Weight Set: best plate-and-collar set with a case **Why it made the list** - You slide plates onto the handles and tighten threaded collars. Its listing counts two 3 lb handles, four 2.5 lb plates, four 5 lb plates and four collars, which makes 19 lb per dumbbell and 38 lb for the pair. - It packs into a carry case with a handle. - The bars have a long threaded section, so extra plates can be added later. **Drawbacks** - Changing weight means unscrewing collars and moving plates, the slowest way to change that Live Science and Wirecutter describe. - The handle knurling is rough, so gloves help. - The smallest plate is 2.5 lb on a 3 lb handle, so you cannot make an even 5 or 10 lb dumbbell. **Skip it if** you change weight often during a workout. A dial or twist set is faster. ### 6. Yaheetech Adjustable Dumbbell Set: best for more total weight **Why it made the list** - Its listing gives 16 plates in four weights, four of each, with threaded bars and spin-lock collars, up to 66 lb for the pair. - The listing names polyethylene plates instead of metal ones. **Drawbacks** - Plastic plates and locks may wear faster than metal. That is our inference from the listing's material line. - The set may arrive with a strong smell that airs out over a few days, and the collars need tightening so plates do not loosen. - The listing gives 19.7 inches in length, which can feel long on some moves. **Watch for this:** [Yaheetech](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-6) sells this set in more than one weight under related listings. Check which one is on the page. **Skip it if** you want a metal set or a quick change. The [Amazon Basics](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-5) plates are metal. ## What we left out, and why We read 124 result cards across Amazon's results for "adjustable dumbbells set". 24 were sponsored, and we skipped them. The other 100 rows were 92 different listings. Seven of those were not adjustable dumbbells at all: fixed rubber, vinyl, hex and cement sets, a dumbbell stand, ankle weights and a kettlebell. We narrowed the rest to 10 contenders, read each set's own Amazon page, and kept six. Four were left out: - **Keppi Adjustable Dumbbells.** A second 5 to 25 lb set that does the same job as the [Lifepro](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-4), and its listing family also covers a 55 lb set, so the two sizes share one pool of reviews. - **CAP ADJUSTABELL Adjustable Dumbbell Set.** Its listing covers 12.5, 25 and 55 lb sizes without saying which one this page sells, and one review describes cast iron plates and star-lock collars, which a dial set would not use. - **FEIERDUN DS2 Adjustable Dumbbells.** A plate set with a connector that turns into a barbell, and its page came back with no review text. - **EQUIPRO Adjustable Dumbbell Set.** A 2 to 5 lb set, and one review describes barbell and kettlebell modes that the listing text we read does not mention, so its reviews may be pooled with another product. Watch for look-alikes. 31 of the 92 listings carry "in-1" or "connector" in the title, and many open with a weight list such as "20/30/45/70/90lbs" instead of a brand. Three listings with the same weight list and the same rounded review count of 2,100 sit side by side in the results. The BowFlex Results Series appears as three separate listings. Wirecutter's top pick, updated October 2, 2026, is the [Core Home Fitness Adjustable Dumbbell Set](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-1), the same set as our top pick, so the table shows it with Wirecutter's label too. Its runner-up, the MX Select MX55 Evolution, did not appear in the Amazon results we read, so it has no row. ## Questions people ask ### How do adjustable dumbbells work? Most work in one of four ways: a digital dock, a dial, a handle twist or spin-lock collars. A dial or handle twist picks up the plates you want from the cradle, and spin-lock collars hold plates you load yourself. ### How much weight should each dumbbell hold? Wirecutter looked for sets that go from 5 or 10 lb up to 50 lb per dumbbell and says that range is enough for most exercisers. Heavier lifters can look at the [NordicTrack](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-3), which reaches 55 lb, or at the [PowerBlock](https://twelvetabs.com/reviews/best-adjustable-dumbbells/#pick-2) with an expansion kit. Prefer a single fixed weight? Our [kettlebell guide](https://twelvetabs.com/reviews/best-kettlebells/) covers that. ### Are adjustable dumbbells worth it? Live Science makes the case that one set with a wide range of weights can be a shrewd purchase, since you would otherwise buy a new fixed pair each time you step up, and you save space and the time spent swapping weights. ### How did TwelveTabs choose these adjustable dumbbells?

AI compared them, read the Amazon pages of 10 contenders and named six picks. AI wrote this guide from that research.
