NordicTrack Adjustable Dumbbells Reviewed: Features Compared

Adjustable dumbbells solve a specific problem: you want a full weight range in your training space without dedicating an entire wall to a fixed dumbbell rack. If you’re training at home and that tradeoff matters to you, the adjustable dumbbells category has more options than it did even a few years ago , and more variation in how those options actually work. Mechanism, weight range, increment size, and footprint all differ meaningfully between designs.

What looks like a simple purchase decision gets complicated fast. The selector mechanism that feels intuitive to one person feels clunky to another. Weight increments that work for isolation exercises leave gaps in compound work. Getting this choice right the first time saves you from selling a pair at a loss six months later.

What to Look For in Adjustable Dumbbells

Selector Mechanism

The mechanism is the thing you’ll interact with hundreds of times before you ever get tired of your dumbbells. There are three dominant designs in this category: dial-select, pin-select, and plate-load with collars. Dial systems (like the classic selectorized design) let you rotate a dial at each end to set the weight , fast, intuitive, and popular for a reason. Pin systems use a selector pin inserted through a weight stack, similar to a cable machine. Plate-load systems are just small barbells with collars, which most people moving up from traditional dumbbells already understand.

Speed matters more than buyers expect. If your programming includes drop sets, supersets, or any circuit work with back-to-back weight changes, a mechanism that takes fifteen seconds to adjust becomes a genuine training bottleneck. Dial systems tend to win on speed; collar systems are slowest but also most durable under abuse.

Durability is the other variable. Plastic selector components are the most common failure point across the entire adjustable dumbbell category. Budget options that use more plastic in the mechanism are worth scrutinizing before purchase.

Weight Range and Increment Size

Most home gym trainees underestimate how much their useful weight range will expand over time. A set that tops out at 25 lbs per hand might serve a beginner well for a year. It becomes inadequate the moment your pressing strength moves past that ceiling.

Increment size is equally important and easier to overlook. A set with 10 lb increments forces you to make larger jumps than you may want, particularly on isolation movements like curls or lateral raises where the difference between 20 and 30 lbs is substantial. Five-pound increments are a reasonable minimum; 2.5 lb increments are genuinely useful for progressive overload, especially at lighter weights.

If you’re deep in the adjustable dumbbells market, it’s worth mapping out your current and likely future training weights before committing to a weight ceiling. Buying a set that maxes out just above your current top working weight is a mistake most people make exactly once.

Footprint and Storage

The whole point of adjustable dumbbells is space efficiency. But the actual footprint varies considerably. Selectorized sets with a tray base are compact when stored but require the tray to be in place during storage , you can’t just set them on a rack. Block-style designs like PowerBlock’s rectangular format are genuinely compact and rack-friendly. Traditional plate-load sets store like barbells: plates off to the side, handles on a rack.

Think about your workflow. If your training space is tight and you’re changing weights mid-set, you want a design that goes back into its storage position quickly and cleanly. A tray that requires precise alignment to seat properly gets annoying fast in a training session.

Build Quality and Grip

Handle diameter and knurling affect how a dumbbell actually feels in your hand. Handles that are too thick are uncomfortable for smaller hands on pressing movements; handles that are too thin don’t provide enough feedback for heavy rowing. Most selectorized dumbbells land in the 32, 34mm handle diameter range, which works for most people.

Knurling , the textured pattern on the handle , varies from aggressive to nearly smooth. Light knurling is fine for moderate weights; heavier work benefits from more grip texture. Rubber-coated handles avoid knurling entirely and feel comfortable but can degrade over time with chalk use.

Top Picks

NordicTrack Select-A-Weight Adjustable Dumbbells

The NordicTrack Select-A-Weight Adjustable Dumbbells use a slide-select mechanism rather than a dial , you push a tab to the desired weight increment, and the plates lock in. It’s a slightly different interaction than the Bowflex-style dial most people picture, and it works cleanly once you get used to the motion.

The set covers a useful range for most home gym trainees, and the tray design keeps everything organized between sets. NordicTrack’s build quality on this product has held up well in long-term user reports , the selector mechanism in particular draws less criticism than comparable budget options. The handle feel is solid without being exceptional.

The main consideration is footprint. Like most tray-based selectorized sets, these require the tray to store properly, which means they’re not drop-and-rack friendly. If your setup involves a dedicated dumbbell station, that’s a non-issue. If you’re improvising storage in a tight space, factor that in.

Core Fitness Adjustable Dumbbell Weight Set

The Core Fitness Adjustable Dumbbell Weight Set uses a dial-select mechanism and has earned a strong customer rating over a long sales history , that review volume across years of purchases tells you something about durability that a newer product can’t demonstrate yet.

The design is compact and the weight range covers the needs of most intermediate home gym trainees. Increment size is reasonable for general training. At the segment of the market this occupies, it competes with several similar-looking designs , what separates it is the accumulated user feedback suggesting the mechanism holds up rather than degrading into stiffness or misalignment over time.

If your training is primarily hypertrophy work , moderate weights, higher reps, frequent weight changes between exercises , this design suits that style well. The dial system is fast enough that it doesn’t interrupt training flow.

PowerBlock Elite EXP Adjustable Dumbbells

The PowerBlock Elite EXP is the option I’d point most people toward when durability and expandability matter more than aesthetics. The block format is polarizing , some people find the rectangular cage design awkward for certain movements, particularly those involving the dumbbell resting against the body , but the build quality is genuinely commercial-grade.

The steel construction is the headline. These are not plastic-heavy selectorized dumbbells that will develop selector slop over years of use. The pin mechanism is simple enough that there’s not much to fail. The Stage 1 set covers 5 to 50 lbs per hand with 2.5 lb increments at the lower end, which is the increment resolution that makes progressive overload tractable.

The expansion kit system is the real long-term value argument. You can add weight range later as your strength demands increase rather than buying a new set outright. For a home gym that’s supposed to last years, that matters. The shape takes some adjustment , pressing movements and rows both work fine once you’ve trained with the format a handful of times.

Marcy 40 lb Adjustable Dumbbell Set with Collars

The Marcy 40 lb Adjustable Dumbbell Set is the plate-load option in this group, and it serves a different buyer than the selectorized sets above. These are essentially compact barbells with spin-lock collars , you load plates, tighten the collars, train, unload. No mechanism to break, no plastic selector to wear out.

The tradeoff is adjustment time. Swapping weight mid-session takes thirty to sixty seconds depending on how many plates you’re moving. If your training involves frequent weight changes , drop sets, circuits, supersets , that friction adds up. If you primarily train straight sets with long rest periods, it’s not a real issue.

The 40 lb ceiling per hand is the practical constraint. This set makes sense for a trainee who is newer to lifting and won’t exceed that ceiling in the near term, or as a secondary set for a home gym that handles lighter accessory work. The build is simple and durable because there’s very little to it , that’s both the appeal and the limitation.

Buying Guide

Matching Weight Range to Your Training Level

The most common mistake in this purchase is buying to your current strength rather than where you’ll be in eighteen months. If you’re pressing 40 lbs per hand now, a set that tops out at 50 lbs will feel limiting sooner than you expect. Beginners who are consistent can outgrow an entry-level set within a year. Intermediate trainees who are already handling moderate weights should be thinking about sets with a 50 lb or higher ceiling per hand.

The PowerBlock EXP’s expansion path addresses this directly , you buy the base weight range and add to it later. That’s worth factoring into any comparison between sets at different price bands.

Mechanism Type and Training Style

How you train should drive which mechanism you choose. Dial and slide-select designs reward styles with frequent weight adjustments: circuit training, drop sets, supersets, and any programming that moves between movements quickly. The two or three seconds it takes to dial to a new weight becomes invisible in training. Pin-select designs are similarly fast. Collar-based plate-load sets like the Marcy suit straight-set training where you load, lift, rest, and lift again without touching the weight until the next exercise.

If you genuinely don’t know your training style yet , you’re early in the process , default to a dial or slide-select mechanism. The flexibility costs nothing and eliminates the possibility of buying a set that slows you down once your programming gets more complex.

Space and Storage Constraints

Selectorized dumbbells with trays have a defined footprint that doesn’t change. You need two tray-width spaces, whatever surface they sit on, and you need to put them back precisely to seat correctly. PowerBlock’s block format is unusually compact for the weight range it covers , the rectangular profile stacks neatly and takes up less floor space than most selectorized pairs at equivalent weight. The Marcy plate-load set is the simplest to store if you have a standard dumbbell rack, since the handles rack like fixed dumbbells and plates store separately.

Measure your available space before purchasing. This sounds obvious and gets skipped constantly. A rough floor plan of your training area with the dumbbell station marked out prevents a common return situation.

Durability and What Fails First

Across the adjustable dumbbell category, the selector mechanism is the component most likely to degrade before anything else. Plastic selector tabs wear, crack, or deform under heavy use. Internal plate engagement systems can develop slop , meaning the selected plates don’t seat fully , which creates noise and imprecise weight loading. The PowerBlock pin-and-selector system avoids most of this because it uses less plastic in the mechanism. Plate-load systems like the Marcy avoid it entirely by having no mechanism at all.

If you’re buying in the budget range and expecting to use the set hard over several years, scrutinize the mechanism construction specifically , not just the overall build. Community forums for home gym equipment are useful here: look for posts from people who have owned a set for two-plus years, not just initial impressions. The full range of adjustable dumbbell options across mechanism types is worth reviewing before you settle on a format.

Who Should Consider a Plate-Load Set

The Marcy and similar collar-based sets get passed over because they look less sophisticated than selectorized designs. For some buyers, that simplicity is the right answer. If you’re building a home gym on a tight budget, want nothing that can mechanically fail, and train in a style that doesn’t require fast weight changes, a plate-load set delivers exactly what you need with no mechanism risk. They’re also genuinely useful as a secondary pair alongside a selectorized set , many home gym owners use a selectorized set for moderate weights and a simple plate-load handle or two for heavier movements where the selectorized ceiling is limiting.

Frequently Asked Questions

How do NordicTrack adjustable dumbbells compare to PowerBlock?

The NordicTrack Select-A-Weight uses a slide-select mechanism and a tray-based design, while the PowerBlock Elite EXP uses a pin selector in a compact block format. PowerBlock’s build is heavier-gauge steel with less plastic in the mechanism, which holds up better under years of heavy use. NordicTrack’s design tends to feel more familiar to users coming from traditional dumbbells. If long-term durability is the priority, PowerBlock is the stronger choice.

What weight range do I actually need for a home gym?

Most intermediate trainees benefit from a set that reaches at least 50 lbs per hand. Beginners can start lower, but strength development tends to outpace expectations in the first year of consistent training. If you do both compound movements like rows and pressing and isolation work like curls and lateral raises, you want enough range to cover both ends , which usually means more headroom above your current working weights than you think you need.

Are adjustable dumbbells durable enough to replace a fixed dumbbell rack?

For most home gym setups, yes , with the caveat that mechanism-based designs require more care than fixed dumbbells. Don’t drop selectorized dumbbells from height; the selector mechanism is not designed to absorb that impact. Plate-load designs like the Marcy 40 lb set are more impact-tolerant since there’s no mechanism to damage. PowerBlock’s steel construction is robust enough that it functions as a long-term rack replacement for most trainees who train hard at home.

What increment size matters most for progressive overload?

Smaller increments matter most at lighter weights and on isolation movements. A 5 lb jump from 15 to 20 lbs on a lateral raise is a 33 percent increase , too large for controlled progressive overload. At heavier weights on compound movements, 5 lb increments are usually workable. Sets offering 2.5 lb increments at the lower end of the range , like the PowerBlock Elite EXP , give you more control over progress, particularly in the first year of training.

Can I use adjustable dumbbells for heavy compound movements like rows and RDLs?

Yes, within the weight ceiling of the set. The practical limit is usually the maximum weight, not the design , rows and Romanian deadlifts at heavier loads are not a problem for well-constructed selectorized or plate-load sets. The one movement to treat carefully is any exercise where the dumbbell might be dropped or swung aggressively, as that can damage the selector mechanism on dial and slide-select designs. For movements where you’re handling near-max weights and fatigue is a factor, the Marcy plate-load format has no mechanism to protect.
