1. Bowflex SelectTech 552: Best Overall Adjustable Dumbbells
The SelectTech 552 is the set most people picture when they think of adjustable dumbbells, and Fitness Volt and T3 both rank it best overall. Turn the dials on each end to choose from 15 settings between 5 and 52.5 pounds. The 2.5-pound steps at lighter weights are great for shoulder and arm work, where jumps of 5 pounds feel huge. Note that some older SelectTech units were recalled; buy new, current-production sets and check the CPSC and Bowflex recall pages if you buy used.
Key specs
- 5 to 52.5 lb per dumbbell; 15 settings
- 2.5 lb steps up to 25 lb, then 5 lb steps
- Dial adjustment with storage trays (stand sold separately)
- About 16.9 x 8.3 x 9 inches; 2-year parts warranty
👍 Pros
|
👎 Cons

What owners say: Owners love how quickly they can move between exercises and how much space the set saves; the long shape on presses and rows is the most common complaint.
2. PowerBlock Elite EXP: Best Expandable Set
PowerBlock’s block-shaped design is much shorter than dial-style dumbbells, so it feels closer to a fixed dumbbell on presses. The Elite EXP starts at 5 to 50 pounds and can be expanded to 70 and then 90 pounds with add-on kits, which makes it a buy-once set for people who expect to get stronger. Fitness Volt calls it the best expandable option.
Key specs
- 5 to 50 lb per dumbbell (Stage 1)
- 5 lb steps, or 2.5 lb with built-in adder weights
- Selector pin; expandable to 70 and 90 lb with kits
- About 11.75 inches long at 50 lb; 5-year limited warranty (home use)
👍 Pros
|
👎 Cons
|
What owners say: Lifters like the compact feel and the expansion path; some find the open-block shape awkward at first.
3. PowerBlock Pro EXP: Best for Heavy Lifters
Garage Gym Reviews rates the Pro EXP its best adjustable dumbbell set, noting it can replace dozens of fixed pairs. It starts at 5 to 40 pounds and expands to 60, 80 or 100 pounds per hand. A magnetic selector pin, color-coded weight bands and a choice of knurled steel or rubber grip handles add polish.
Key specs
- 5 to 40 lb base, expandable to 100 lb per dumbbell
- 2.5 or 5 lb steps
- Magnetic selector pin; color-coded bands
- 38 mm handle; 5-year limited residential warranty
👍 Pros
|
👎 Cons
|
What owners say: Strong lifters praise the build and the ability to go heavy without a full rack; the total cost of expansion is the main concern.
4. Bowflex SelectTech 1090: Best Heavy Dial-Style Set
If you want the convenience of a dial but need more weight, the 1090 goes from 10 to 90 pounds in 5-pound steps. Garage Gym Reviews praised how efficient and simple the adjustment dial is. It is large, and stock can be limited, so check availability before you plan around it.
Key specs
- 10 to 90 lb per dumbbell; 17 settings
- 5 lb steps; dial adjustment
- About 17.5 x 9.5 x 10 inches
- 3-year parts warranty
👍 Pros
|
👎 Cons
|
What owners say: Owners like reaching 90 pounds with a quick turn; many say the size makes curls and presses feel clumsy.
5. NordicTrack 55 Lb. Select-A-Weight: Best Value
NordicTrack’s set uses cast-iron plates and knurled metal handles, giving it a more traditional feel than many plastic-heavy designs. Fitness Volt names it a top budget 55-pound choice. You set the weight by sliding pins at each end, which takes a bit longer, and it starts at 10 pounds.
Key specs
- 10 to 55 lb per dumbbell; 15 settings
- Slide-in pin adjustment at each end
- Cast-iron plates; knurled metal handles
- About 16.5 inches long fully loaded; 1-year limited warranty
👍 Pros
|
👎 Cons
|
What owners say: Buyers like the solid feel for the price; the pin system and lack of light settings draw complaints.
6. Core Home Fitness Adjustable Dumbbells: Best for Fast Changes
Core Home Fitness uses a twist-handle system: set the dumbbell in its base, twist the handle and lift. That makes it great for circuits and supersets where you change weights often. It ranges from 5 to 50 pounds in 5-pound steps.
Key specs
- 5 to 50 lb per dumbbell; 10 settings
- Twist-handle adjustment
- About 14.5 x 7.9 x 7.5 inches each
- 2-year parts warranty; optional stand
👍 Pros
|
👎 Cons
|
What owners say: Owners like how quick the twist is during workouts; some notice a bit of plate movement.
7. PowerBlock Sport EXP: Best PowerBlock on a Budget
The Sport EXP brings PowerBlock’s compact block design and selector-pin speed to a lower price than the Elite. It covers 5 to 50 pounds in 5-pound steps and can be expanded with stage kits. Unlike the Elite EXP, it does not include a stand.
Key specs
- 5 to 50 lb per dumbbell; 10 settings
- Selector pin; expandable with stage kits
- About 13.5 x 7 x 8 inches
👍 Pros
|
👎 Cons
|
What owners say: Buyers like the price and compact footprint; some later wish they had bought a model with finer steps.
8. NÜOBELL Adjustable Dumbbells: Best Traditional Feel
NÜOBELL dumbbells look and feel close to fixed dumbbells, with a compact shape and knurled 32 mm handle. You twist the handle while the dumbbell sits in its cradle and it locks when lifted. Garage Gym Reviews gave it top marks for adjustment speed but noted the plastic internal parts mean you must never drop it.
Key specs
- 5 to 50 lb or 5 to 80 lb per dumbbell; 5 lb steps
- Twist-handle adjustment; cradles included
- 32 mm knurled handle
- 50-80 lb expansion kit sold separately
👍 Pros
|
👎 Cons
|
What owners say: Owners rave about how natural it feels; durability of the plastic components is the recurring worry.
9. Yes4All Adjustable Dumbbell Set: Best Budget
Yes4All’s classic spin-lock set uses cast-iron plates on threaded handles with star-lock collars. It is far slower to change than selector-style sets, but it costs a fraction as much and an optional connector turns the pair into a short barbell. It comes in many total weights.
Key specs
- Cast-iron plates with spin/star-lock collars
- 14-inch handles, 1-inch diameter
- Sold in many total weights (for example, a 50 lb pair)
- Optional barbell connector
👍 Pros
|
👎 Cons
|
What owners say: Budget buyers say it gets the job done for basic training; changing plates mid-workout is the common frustration.
How to choose adjustable dumbbells
- Weight range. A 5 to 50 or 52.5 lb set covers most beginners and intermediates. Stronger lifters should look at 80 to 100 lb sets or expandable systems.
- Increments. 2.5 lb steps help on shoulder and arm exercises. Sets that start at 10 lb can be too heavy for lateral raises and rehab-style moves.
- Adjustment mechanism. Dials and twist handles are fastest; selector pins are quick and sturdy; spin-lock plates are cheapest but slowest.
- Size and shape. Dial sets are often 16 to 17.5 inches long, which can bump your legs and shoulders. Block designs are shorter.
- Durability and drops. Most adjustable dumbbells should not be dropped, and some warranties exclude drop damage.
- Stand and storage. A stand puts the cradle at waist height and saves your back; check whether it is included.
FAQ
Are adjustable dumbbells worth it?
For most home gyms, yes. One pair can replace 10 to 30 fixed pairs and takes up a small corner, so the upfront cost pays off in space and money over time.
What weight range should I buy?
Most people do well with a set that tops out around 50 pounds. If you already press or row heavier, choose an 80 to 100 lb or expandable set so you do not outgrow it.
Can you drop adjustable dumbbells?
Generally no. Internal locking parts can crack, and several brands exclude drop damage from the warranty. Set them down in the cradle or on a mat, and follow the manufacturer’s use limits.
Adjustable or fixed dumbbells?
Adjustable sets save space and cover many weights. Fixed dumbbells are tougher, faster for supersets and better if you tend to drop weights, but a full rack costs more and takes much more room.
