Top 5 Adjustable Dumbbells at a Glance
How to Choose the Best Adjustable Dumbbells
The best adjustable dumbbells depend on how you train. Before buying, consider the maximum weight per dumbbell, minimum weight, adjustment increments, handle shape, overall width, and how quickly you can change resistance. Traditional-feeling designs can be especially comfortable for curls, presses, flyes, goblet squats, and other movements where the shape of the dumbbell matters.
You should also think about durability. Adjustable dumbbells contain more moving parts than conventional fixed-weight dumbbells, so construction quality and careful handling are important. If you regularly perform heavy compound movements, a particularly sturdy design may be more valuable than the smallest footprint.
Finally, consider how much room you have available. All five models can replace multiple pairs of conventional dumbbells, but their shapes and storage requirements differ considerably. A compact option can be ideal for smaller spaces, while a heavier premium model may be better for a dedicated garage or basement gym.
1. SMRTFT Nüobell 80lb Dumbbells
The SMRTFT Nüobell 80lb Dumbbells are an excellent choice for lifters who want adjustable equipment that feels remarkably close to a traditional dumbbell. With up to 80 pounds per dumbbell, they offer enough resistance for serious full-body training while replacing a large collection of fixed-weight pairs. The turn-and-click adjustment system also makes it easy to select the desired load without dealing with separate plates.
One of the biggest advantages is the familiar shape and handling. The dumbbells work well for accessory movements such as curls, skullcrushers, flyes, and goblet squats, while still providing the weight capacity needed for heavier exercises. Metal plates and handles contribute to a premium feel, and the selected weight is displayed directly on the dumbbell.
The included rack is the main area where expectations may be lower than the quality of the dumbbells themselves. The plastic construction may require more care when repeatedly re-racking heavy metal weights. Still, for dedicated home-gym users who prioritize premium construction, fast adjustment, and a traditional dumbbell feel, the Nüobell is one of the strongest choices here.
| Pros | Cons |
|---|---|
| Up to 80 lb per dumbbell | Rack may need careful handling |
| Excellent traditional dumbbell feel | Premium price category |
| Fast turn-and-click adjustment | Better suited to dedicated home gyms |
2. BowFlex Results Series 552 SelectTech Dumbbells
The BowFlex Results Series 552 SelectTech Dumbbells are designed to replace up to 15 pairs of traditional dumbbells while offering a broad selection of resistance levels. They adjust from 5 to 52.5 pounds per dumbbell in 2.5-pound increments, giving users useful control over progression for strength training, hypertrophy, and general fitness.
The selection dials on both sides make weight changes straightforward, although each adjustment requires docking the dumbbell and setting both sides. Compared with a single-twist design, this takes a little more effort, but the smaller increments can be valuable when you want to make precise increases. The weight distribution also feels relatively familiar compared with some bulkier adjustable systems.
The updated design incorporates premium metal components and is built for regular home-gym use. Its wider shape can feel cumbersome for certain movements, particularly exercises where the dumbbell travels close to the body. The 52.5-pound ceiling may also limit advanced lifters, but for beginners and intermediate users, the SelectTech 552 provides an impressive balance of versatility and adjustability.
| Pros | Cons |
|---|---|
| 5 to 52.5 lb range | Requires adjustment on both sides |
| 2.5-lb increments | Wide shape can feel cumbersome |
| Replaces multiple dumbbell pairs | 52.5 lb may be limiting for advanced lifters |
3. NordicTrack 55 Lb. Select-A-Weight Dumbbells
The NordicTrack 55 Lb. Select-A-Weight Dumbbells offer a sturdy option for intermediate home-gym users who want a straightforward adjustable system. Each dumbbell covers 10 to 55 pounds, with adjustments available in 2.5-pound increments. The combination of metal plates, a knurled metal handle, and a robust outer casing gives the set a reassuringly solid feel.
A major benefit is the included storage tray. The dumbbells arrive assembled and can be stored neatly without requiring a large rack. Weight adjustments are relatively easy, and the knurled handle provides useful grip security as the resistance increases. The design works particularly well as a supplemental set for people who already understand basic gym movements.
One drawback is that the dumbbells themselves do not display the selected weight once they are removed from the tray, so users have to remember the setting. The relatively broad plates can also make some accessory movements less comfortable. Even so, the solid construction, useful 2.5-pound increments, and 55-pound maximum make this a capable choice for intermediate home workouts.
| Pros | Cons |
|---|---|
| Up to 55 lb per dumbbell | Selected weight is not displayed on the dumbbell |
| 2.5-lb adjustment increments | Broad plates can affect accessory movements |
| Sturdy knurled metal handle | More noise than some competing designs |
4. REP Fitness QuickDraw Adjustable Dumbbells
The REP Fitness QuickDraw Adjustable Dumbbells stand out as a practical option for users who want a streamlined adjustable design without jumping immediately into the highest weight ranges. The set uses steel weight plates and an alloy steel handle, giving it a durable construction that is well suited to regular home-gym training.
The adjustment system is one of the QuickDraw’s biggest strengths. Its Lock-N-Load mechanism allows users to change the weight by flipping a switch on each dumbbell. Adjustments can therefore be made quickly between exercises, which is particularly useful during supersets, circuits, or workouts where minimizing downtime matters.
The standard configuration spans 5 to 30 pounds in 2.5-pound increments, making it particularly attractive for beginners, general fitness users, and accessory movements. Lifters who need heavier resistance may prefer one of REP Fitness’s heavier QuickDraw configurations. For users who value compactness, simple operation, and durable construction, this is a very appealing choice.
| Pros | Cons |
|---|---|
| Fast Lock-N-Load adjustment | 30-lb configuration may be too light for advanced lifters |
| Steel plates and alloy steel handle | Heavier configurations cost more |
| 2.5-lb increments | Less suitable for very heavy compound lifting |
5. PowerBlock Pro 50 Adjustable Dumbbells
The PowerBlock Pro 50 Adjustable Dumbbells take a very different approach from traditional dumbbell-shaped adjustable weights. Their compact block-style design covers 5 to 50 pounds per dumbbell in 2.5-pound increments, creating a versatile training tool that is especially useful when floor space is limited.
The square-shaped construction is particularly practical because the dumbbells can be placed on the floor without rolling away. They are also useful for demanding movements such as dead-stop rows, Romanian deadlifts, heavy presses, farmer’s walks, lunges, and thrusters. Expansion options make the PowerBlock system attractive to users who expect their strength to increase over time.
The pin-and-lock adjustment mechanism is straightforward and avoids some of the jamming issues associated with other adjustable systems. The main compromise is that the shape does not replicate the feel of a conventional dumbbell, and some components use plastic construction. Nevertheless, the Pro 50 remains an exceptionally versatile choice for home workouts, particularly when compact storage and a wide range of exercises are priorities.
| Pros | Cons |
|---|---|
| 5 to 50 lb range | Block-style shape feels different from traditional dumbbells |
| Compact and space-efficient | Some components use plastic |
| Expansion options available | Adjustment system is less visually conventional |
