Our top picks
Bowflex SelectTech 552 Adjustable Dumbbells
The Bowflex SelectTech 552 is a bestseller for good reason. It replaces 15 sets of dumbbells, adjusting from 5 to 52.5 pounds in 2.5-pound increments. The dial system is intuitive: turn the dial to select weight, lift, and go. Owners report the weight distribution is balanced, and the contoured handle feels comfortable during curls and presses. The included stand keeps the dumbbells organized and folds for storage. However, they are longer than most adjustable dumbbells, which may feel unwieldy for smaller users.
Pros
- Wide weight range with small increments
- Balanced and sturdy construction
- Easy dial adjustment
Cons
- Longer than some alternatives
- Plastic base may fade over time
PowerBlock Elite EXP Adjustable Dumbbells
PowerBlock Elite EXP uses a unique selector pin system that allows you to change weight in seconds by sliding the pin into the desired plate. It expands from 5 to 50 pounds per hand, with an expansion kit available up to 90 pounds. The square design feels different in hand but offers a secure grip. Users praise the speed of adjustment, ideal for circuit training. The storage cradle is compact, and the dumbbells stack neatly. The main downside is the blocky shape, which can be awkward for certain exercises like tricep extensions.
Pros
- Lightning-fast weight changes
- Expandable weight capacity
- Compact storage footprint
Cons
- Blocky shape may not suit all grips
- Weight plates are exposed
NordicTrack Select-A-Weight Adjustable Dumbbells
NordicTrack offers an affordable entry into adjustable dumbbells with a similar dial system to Bowflex. It covers 5 to 50 pounds in 5-pound increments, which is sufficient for many users. The build quality is decent for the price, though some users note the plastic base feels less premium. The dumbbells come with a convenient tray, and the weight plates are encased for safety. They are not as balanced as pricier models, but they provide a solid workout for general fitness.
Pros
- Affordable price point
- Simple dial adjustment
- Compact tray included
Cons
- Larger weight increments
- Less durable than premium options

Users appreciate the ability to do barbell exercises without needing a separate bar. The handles are knurled for grip, and the set is very affordable. The main drawback is the time-consuming adjustment process.
Pros

However, the twist-lock can loosen if not tightened properly, and the weight range may be limited for advanced lifters.

Cons
- Lock can loosen during exercise
- Not for heavy advanced lifting

This model is ideal for serious lifters who need heavy resistance. The downside is that the plates are not encased, so they take up more space and require careful storage.
Pros

- Knurled handles for grip
Cons
- Not a single compact unit
- Requires assembly and storage space

Common questions
What does ‘foldable’ mean for adjustable dumbbells?
Foldable adjustable dumbbells typically refer to the design where the weight plates are stored in a tray or cradle that can be folded or stacked for compact storage. Some models have a base that collapses, while others are simply compact enough to fit in tight spaces. This feature is ideal for home gyms with limited room.
Are adjustable dumbbells as effective as traditional fixed-weight dumbbells?
Yes, adjustable dumbbells can be just as effective for strength training. They allow you to perform the same exercises with a variety of weights. The main difference is the adjustment time, which can interrupt the flow of a workout if you need to change weights frequently. However, many models offer quick adjustment mechanisms to minimize downtime.
How much weight do I need for serious training?
For serious training, it’s recommended to have a range that allows you to progress. Starting with a set that goes up to 50 pounds per hand is a good baseline for many lifters. If you can already lift more than 50 pounds for exercises like rows or deadlifts, consider a model that offers higher weight capacities, such as PowerBlock with expansion kits.
Can I do drop sets with adjustable dumbbells?
Yes, but the speed of adjustment is key. Dial and selector pin systems allow for quick changes, making drop sets more practical. Screw-lock systems take longer, which may reduce the effectiveness of drop sets. Look for models with fast adjustment if you plan to do drop sets regularly.
Are there safety concerns with adjustable dumbbells?
Safety depends on the design. Ensure that the adjustment mechanism is secure and that plates do not shift during exercise. Screw-lock models require you to tighten the collars properly. Always check that the dumbbells are on a stable surface when adjusting. Also, be mindful of the weight distribution; some models are longer, which can affect balance.
How do I maintain my adjustable dumbbells?
Maintenance is generally simple. Wipe down the handles and plates after use to remove sweat. Check for loose screws or pins periodically. For models with plastic components, avoid leaving them in direct sunlight to prevent fading. Lubricate moving parts like dials or pins if they become stiff.
Can I use adjustable dumbbells for exercises that require a barbell?
Some adjustable dumbbells come with a connector bar that turns them into a barbell, allowing you to do exercises like bench presses or rows. However, the total weight may be limited compared to a standard barbell. If you need to lift very heavy, consider a dedicated barbell setup.
What is the warranty on adjustable dumbbells?
Warranties vary by brand. Bowflex offers a 2-year warranty, PowerBlock provides a 5-year warranty on most parts, and others may offer limited lifetime warranties. Always check the manufacturer’s warranty before purchasing. It’s important to register your product to ensure coverage.
Do adjustable dumbbells come with a stand or tray?
Many models include a stand or tray for storage. For example, Bowflex includes a stand, and NordicTrack includes a tray. Some models like Yes4All require you to purchase a stand separately. Consider the storage solution that fits your space when making a decision.
Can I adjust the weight while the dumbbell is on the floor?
Yes, most adjustable dumbbells are designed to be adjusted while resting on a flat surface. Simply place them on the floor or a rack, change the weight, and lift. Ensure that the dumbbell is stable and that your fingers are clear of the adjustment mechanism.
Our pick
For most serious trainees, the Bowflex SelectTech 552 offers the best combination of weight range, adjustment speed, and build quality. Its wide range and small increments support progressive overload, and the dial mechanism is quick enough for circuit training. The main drawback is its size, which may be an issue for smaller users. If you prioritize speed above all, the PowerBlock Elite EXP is a close second, but its shape takes getting used to. Budget-minded lifters can trust the Marcy set for its versatility and low cost, though it lacks the convenience of dial systems. Ultimately, invest in the model that fits your strength level and space constraints; a quality pair will last for years.
