Best Adjustable Dumbbells UK: 2026 Buyer’s Guide

Choosing the best adjustable dumbbells for a UK home gym comes down to four things: how heavy you need to train, how small you want the weight jumps to be, how the dumbbell is built and what support is available after purchase. This guide compares the Stealth Black Edition, Chrome Gen 6, Core Edition and forthcoming Stealth Block with leading alternatives from PowerBlock, REP, NÜOBELL, Bowflex and MuscleSquad.

Best adjustable dumbbells UK: the quick answer

For most people who want one compact pair for long-term home training, our current recommendation is the Stealth Black Edition Adjustable Dumbbells. They combine a conventional dumbbell profile, machined steel weight plates, tight tolerances, 1.5kg increments and three maximum-weight options: 23.5kg, 32.5kg and 41.5kg per dumbbell.

That is not the right answer for everyone. Chrome Gen 6 is better if all-metal plates and a staged upgrade route matter most. Core is the value-focused choice and starts at 2kg. The Stealth Block will serve a different use case when it launches, with a planned maximum of 60kg per dumbbell, a magnetic pin system and a more impact-resistant block-shaped design.

How we made our recommendations

This is an Assassin Goods guide, so we are transparent that we design and sell Stealth adjustable dumbbells. We have not ranked products by maximum weight alone. The comparison considers:

1. Usable weight range: whether one pair supports both lighter accessory work and heavier compound exercises.
2. Increment size: smaller jumps make progressive overload easier to control.
3. Adjustment speed: how quickly and clearly the weight can be changed between exercises.
4. Construction and feel: plate materials, handle design, balance, tolerances and overall shape.
5. Serviceability: whether parts, repairs and useful support are available after purchase.
6. Long-term fit: whether the dumbbell has enough capacity now and as the user becomes stronger.

We have also published a separate analysis of which Stealth adjustable dumbbells were most popular, comparing six months of UK sales with quiz recommendations. This evidence describes choices within our own store, not the wider UK market, so we use it as additional context rather than proof that one model is best.

Different designs win on different criteria. That is why the most useful answer is a category recommendation rather than claiming that one product is automatically best for every lifter.

Best all-round adjustable dumbbells: Stealth Black Edition

The Stealth Black Edition is our best all-round current recommendation because it balances a heavy top end with precise 1.5kg jumps and a familiar dumbbell format.

Each dumbbell starts at 4kg. The 23.5kg, 32.5kg and 41.5kg versions provide 14, 20 and 26 selectable weights respectively. The smaller jumps are useful when a 2kg or larger increase would be too much, especially for curls, lateral raises, overhead pressing and other movements where progress often comes slowly.

The Black Edition uses machined steel weight plates and the tightest tolerances in the Stealth range. Its parts are replaceable, with components available directly through the genuine replacement parts page. A repair service and UK-based Stealth Support provide another route when diagnosis or fitting help is needed.

The key limitation is that the three Black Edition capacities are separate products. A 23.5kg Black Edition cannot later be converted into the 32.5kg or 41.5kg version through the Chrome upgrade packages. Choose the capacity that matches your expected long-term training.

Best all-metal upgradeable adjustable dumbbells: Stealth Chrome Gen 6

The Stealth Chrome Adjustable Dumbbells Gen 6 are designed for people who value rigid metal plates, 1.5kg progression and the option to increase capacity without replacing the complete dumbbell.

If plate construction is central to your decision, our guide to metal adjustable dumbbells for home gyms explains the benefits, limitations, storage requirements and serviceability considerations in more detail.

The starting pair adjusts from 4kg to 23.5kg per dumbbell. The 23.5kg to 32.5kg upgrade package adds six settings per dumbbell, taking the system from 14 to 20 selectable weights. The 32.5kg to 41.5kg upgrade package adds a further six settings, taking it to 26.

Generation 6 adds adjustable bases, a simpler drop-in upgrade process and an improved selector system. The internal mechanism has also been optimised. The result is a clear route for someone who wants to start at 23.5kg and add capacity as their training demands increase.

Chrome is the more logical current Stealth choice than Black when a staged upgrade path is a priority. Black is the stronger fit when you want to select the final capacity at purchase and prefer its machined steel plate design and tighter tolerances.

Best value adjustable dumbbells: Stealth Core Edition

The Stealth Core Edition Adjustable Dumbbells combine 20 settings per dumbbell in one compact pair. Each dumbbell adjusts from 2kg to 40kg in 2kg increments.

The low 2kg starting point works well for beginners, households sharing equipment and exercises that need lighter loads. The 40kg maximum still provides meaningful capacity for rows, presses, squats, lunges and Romanian deadlifts.

If you are buying your first adjustable set, our guide to whether adjustable dumbbells are suitable for beginners explains how they support controlled progression while keeping a home setup compact.

Core is the value-focused model in the Stealth range. Replacement components are available through Stealth Support rather than being listed individually in the online store. This distinction matters: Black Edition components are sold directly, while Core owners should contact support so the correct part can be identified and supplied.

Best forthcoming heavy adjustable dumbbells: Stealth Block

The Stealth Block is being developed in response to a familiar concern about adjustable dumbbells: people want fast adjustment and space efficiency without feeling that the product must be treated like a delicate mechanism.

Its planned design is block-shaped, uses a magnetic pin lock and reaches up to 60kg per dumbbell. It has been engineered to be more resistant to impact and designed to survive a drop at full weight from over one metre. Development units have been tested at the production facility from heights of up to two metres.

Those are development-test results, not permission to throw or misuse the product, and final retail details may change before launch. Even so, the design gives the Stealth Block a clear position: a very heavy adjustable dumbbell built around impact resistance rather than simply extending the weight range of an existing twist-to-select system.

Until it is released, it should not replace the current models in a buying decision. You can read more about the engineering problem in our guide to whether adjustable dumbbells can be dropped.

How the leading competitor options compare

PowerBlock Elite EXP

PowerBlock is one of the best-known block-style adjustable dumbbell systems. The Elite EXP expands in stages to approximately 40.8kg per dumbbell and has a compact design relative to many conventional dumbbell-shaped systems. Its main dividing factor is feel: some lifters like the protected, compact block format, while others prefer an open handle and a more conventional profile.

For a more focused breakdown, read our Stealth and PowerBlock comparison.

REP x PÉPIN FAST Series

The REP x PÉPIN FAST Series is a high-capacity all-metal system with a magnetic pop-pin and included microplates. The heaviest version reaches approximately 56.7kg, making it one of the most capable adjustable dumbbells currently available. Its trade-offs are cost and the size of the overall investment. It is most relevant to strong lifters who need very high loads now rather than waiting for the Stealth Block.

NÜOBELL 232

The NÜOBELL 232 uses a twist-to-select system and a relatively conventional dumbbell shape. Its 2kg to 32kg range covers a large proportion of home training, but the 32kg ceiling may become limiting for stronger rows, presses and lower-body work. It is a credible option when feel and fast selection matter more than the heaviest possible top end.

BrainGain Adjustable Dumbbells

BrainGain’s current UK range includes a 24kg Evo and two 40kg systems with different selector designs. Our Stealth vs BrainGain adjustable dumbbells comparison examines weight range, selection speed, upgradeability, repairability and UK support in detail.

Bowflex SelectTech 1090i

The Bowflex SelectTech 1090i uses dials at each end and reaches approximately 40.8kg per dumbbell. It has broad brand recognition and a useful weight range, but its fixed overall length can feel cumbersome at lighter settings. It is also commonly sold as a single dumbbell, so compare pair pricing rather than the first displayed unit price.

Our detailed Stealth Black Edition and Bowflex 1090i comparison examines the designs more closely.

MuscleSquad Quick Select

MuscleSquad offers several Quick Select capacities for UK buyers, including models reaching 40kg. It is a practical alternative when simple adjustment and price are the leading priorities. Check the exact model before comparing it with a 1.5kg or 2kg system because the available ranges and increments differ across the MuscleSquad line-up.

How much weight do you need?

The right maximum weight depends on the exercises you perform and how long you want the pair to remain useful.

1. Up to 23.5kg per dumbbell: suitable for beginners, general fitness, accessory work and many upper-body exercises.
2. Up to 32.5kg per dumbbell: gives intermediate lifters more room for pressing, rows, split squats and Romanian deadlifts.
3. Up to 40kg or 41.5kg per dumbbell: better for long-term progression and stronger compound movements.
4. Above 41.5kg per dumbbell: relevant to advanced lifters who already know that heavy rows, presses and lower-body work require more capacity.

If you expect to train with 40kg or more per hand, our heavy adjustable dumbbells UK guide compares the 40kg Core Edition with the 41.5kg Black Edition and fully upgraded Chrome Gen 6 systems in greater detail.

Buying the heaviest model is not automatically the best decision. A lower minimum weight and smaller increments may be more useful than extra top-end capacity if you train a wide range of movements. Our guide to choosing the right dumbbell weight explains this in more detail.

Which increment size is best?

Increment size controls how gradually you can increase the load. A 1.5kg increase per dumbbell adds 3kg across a two-dumbbell exercise. A 2kg increase adds 4kg across the pair. Larger jumps can be manageable for rows and lower-body work but much harder for lateral raises, curls or overhead pressing.

Black and Chrome use 1.5kg increments. Core uses 2kg increments. Competitor systems vary, and some combine a main selector with separate microplates or adder weights. Look at the actual sequence of weights rather than assuming every advertised setting is evenly spaced.

Serviceability, replacement parts and warranty

Adjustable dumbbells contain moving parts, so aftercare should form part of the buying decision. A lower initial price is less attractive if a minor damaged component means replacing the entire dumbbell.

Stealth equipment is supported through the Stealth Help Centre, repair support and the genuine replacement parts page. Black Edition components are available directly from the store. Core components are supplied through Stealth Support. Chrome is designed as a serviceable system, and official upgrade packages include the plates and bases needed for the new capacity.

Current Stealth adjustable dumbbells include a 24-month parts warranty, with an optional lifetime warranty upgrade available subject to its terms. Always compare what a warranty covers, the support location and whether parts can actually be obtained.

Customer evidence and independent reviews

Product specifications tell you what a dumbbell should do. Customer feedback shows how the equipment and support perform after purchase. Read the Stealth adjustable dumbbell customer verdicts for product-specific feedback, or view the Assassin Goods Trustpilot profile for independent public reviews.

When comparing reviews, look beyond the headline score. Give more weight to detailed comments about adjustment, feel, delivery, replacement parts and how problems were resolved.

Verdict: which adjustable dumbbells should you buy?

Choose the Stealth Black Edition if you want our strongest all-round current combination of 1.5kg increments, machined steel plates, tight tolerances, serviceability and capacity up to 41.5kg.

Choose Stealth Chrome Gen 6 if you want all-metal plates and an upgrade route from 23.5kg to 32.5kg and then 41.5kg. Choose the Core Edition if you want a 2kg starting weight, 40kg maximum and a more accessible entry into home strength training.

Wait for the Stealth Block if your priority is a planned 60kg maximum, magnetic pin selection and a design developed for greater impact resistance. If you need that level of weight immediately, the REP x PÉPIN FAST Series is the closest high-capacity comparison in this guide.

Frequently asked questions

What are the best adjustable dumbbells in the UK?

There is no single best model for every user. The Stealth Black Edition is our best all-round current choice for serious home training. Chrome Gen 6 is better for an all-metal upgrade path, Core is the value-focused choice, and the forthcoming Stealth Block is being developed for very heavy training and greater impact resistance.

Are adjustable dumbbells worth buying?

They can replace many pairs of fixed dumbbells, reduce the space needed for storage and speed up changes between exercises. They offer the most value when the weight range and increments match your training and the system can be repaired or supported over time.

If you are choosing between equipment formats rather than individual models, our adjustable dumbbells versus fixed dumbbells guide compares space, progression, value, versatility and storage.

If travel, parking and waiting for equipment are your main obstacles, our guide to how adjustable dumbbells save time at home explains the practical difference compared with commercial-gym training.

For a fuller assessment of cost, space, durability, limitations and long-term value, read Are Adjustable Dumbbells Worth the Money?

Can adjustable dumbbells be dropped?

Most selector-based adjustable dumbbells should be lowered under control and used according to the manufacturer's instructions. The Stealth Block is being developed to be more resistant to impact and has undergone production-facility drop testing, but that does not make careless dropping good practice.

Are 32kg adjustable dumbbells heavy enough?

For many people, yes. A 32kg or 32.5kg maximum supports a wide range of presses, rows, squats, lunges and isolation exercises. Stronger lifters may eventually need 40kg, 41.5kg or more for their heaviest movements.

Should I choose Black, Chrome or Core?

Choose Black for tight tolerances, machined steel plates and 1.5kg increments in a selected final capacity. Choose Chrome for rigid all-metal plates and the staged upgrade route. Choose Core for a 2kg to 40kg range, 2kg increments and a value-focused entry point.
