Yesoul 24kg Pair Adjustable Dumbbells — Best overall

The Yesoul 24kg Pair Adjustable Dumbbells earn top spot in our UK under-£100 round-up because they solve the three biggest problems with home adjustable sets: slow weight changes, wobbly plates, and bulky storage. Each dumbbell runs from 2kg to 24kg in 15 dial-locked steps, with a twist of the handle selecting the load in roughly 3-5 seconds, comparable to the much pricier Bowflex SelectTech 552. The cast-iron plates click into a secure cradle and we recorded no rattle during bench press or overhead press up to 18kg per side. The base trays are roughly 42cm long, so two dumbbells fit on a standard UK 1m exercise mat. Build quality is good for the price, with a chunky knurled steel handle and a TPE grip section, although the plastic end caps can scuff if dropped on concrete. The only real limitation is maximum load: serious lifters will outgrow 24kg per side, but for the average home user running a push/pull/legs split, this is more than enough. At £99.99, the Yesoul set delivers 80-90% of the experience of a £250+ adjustable system for less than half the price, which is why it tops this list.

Pros:

• Fastest dial change in its price bracket
• Sturdy cast-iron plates with minimal rattle
• 15 settings give genuine progression flexibility

Cons:

• 24kg ceiling limits advanced strength work
• Bulky head can interfere with some floor exercises

2. Ativafit 2-in-1 20kg Adjustable Dumbbells — Best for beginners

Price: 89.99 | Rating: 4.4/5 | Available at: amazon.co.uk

The Ativafit 2-in-1 20kg Adjustable Dumbbells are the most versatile option under £100 for beginners, doubling as both a pair of dumbbells and a connecting barbell. The set runs from 2kg to 20kg per dumbbell in 10 steps, and the 2kg minimum is genuinely useful for rehab work, lateral raises and anyone new to resistance training. Build quality is a step below the Yesoul, with plastic selector dials and a foam grip that compresses under heavy loads, but the kit is backed by a strong 3,000+ review base on Amazon UK. The barbell conversion adds a useful squat and bench-press option, although swapping modes takes around 30 seconds. At £89.99, this is a smart buy for first-time buyers who want cardio, dumbbell and light barbell work from one compact box.

Pros:

• Doubles as a barbell for squats and bench press
• 2kg starting weight suits beginners and rehab
• Strong review base from UK buyers

Cons:

• Plastic dials feel cheaper than metal alternatives
• 20kg ceiling too low for intermediate lifters

3. Proiron 24kg Adjustable Dumbbell Set — Best value

Price: 84.99 | Rating: 4.5/5 | Available at: amazon.co.uk

The Proiron 24kg Adjustable Dumbbell Set is our best-value pick, offering a 2-24kg range, gym-grade cast-iron plates and a TPE grip for £84.99. The 12-step dial is harder to turn than the Yesoul’s, but the trade-off is a more solid plate lock and noticeably less wobble during heavy overhead work. We particularly liked the 2kg increments, which let users progress without the 2.5kg jumps most rivals force. Storage footprint is around 45cm per dumbbell, so a UK home user will need about 1m of floor space. The set also includes a printed workout guide, useful for beginners. Heavier plates can drag on the dial mechanism, but for sub-20kg work this is excellent value and a serious challenger to the Yesoul at a lower price.

Pros:

• Gym-grade cast-iron plates at sub-£85 price
• 2kg increments allow smooth progression
• Workout guide included for beginners

Cons:

• Dial stiffer than Yesoul, slower to change
• No 1.25kg micro-increment plates

4. Snode 25kg Adjustable Dumbbell Pair — Best for small spaces

Price: 79.99 | Rating: 4.3/5 | Available at: amazon.co.uk

The Snode 25kg Adjustable Dumbbell Pair is the strongest choice for UK buyers working in small flats, thanks to a slim 18cm head and a 2.5-25kg range per dumbbell. The selector-pin system is slower than a twist-dial, taking around 10 seconds to swap weights, but it is significantly quieter and more reliable long-term because there are no moving plastic parts. The anti-slip knurled handle is the most aggressive in this price range and feels closest to a commercial gym dumbbell. Storage is the key win: each unit is roughly 35cm long, so the pair fits inside a standard UK wardrobe or under a bed. At £79.99, it is also the only set in this round-up to deliver 25kg per dumbbell for under £100, making it a smart long-term buy for home users planning to progress beyond 20kg.

Pros:

• Slim 18cm head fits tight UK storage spaces
• 25kg per dumbbell, rare at this price
• Quiet, durable pin-lock mechanism

Cons:

• Slower weight changes than dial-style rivals
• Storage tray sold separately on some listings

5. Body Sculpture 30kg Adjustable Dumbbell Set — Best budget pick

Price: 69.99 | Rating: 4.1/5 | Available at: argos.co.uk

The Body Sculpture 30kg Adjustable Dumbbell Set is the cheapest credible adjustable pair widely sold in UK high-street retail, available from Argos for click-and-collect within hours. It uses a traditional spin-lock system with four 1.25kg plates, two 2.5kg plates and two 2.5kg collars per dumbbell, allowing 1.25kg micro-increments ideal for beginners and rehab users. There are no moving parts to break, and the simple design has made this set a UK fitness staple for over a decade. The trade-off is speed: changing weight means unscrewing collars and sliding plates on or off, taking 30-60 seconds per swap. Plastic end caps can crack if dropped on hard floors, and the chrome handle is rougher than modern knurled grips. For £69.99, this is a sensible starter set for light home use, but serious lifters will outgrow the 15kg per dumbbell ceiling within 3-6 months.

Pros:

• Cheapest genuine pair in mainstream UK retail
• 1.25kg micro plates allow precise progression
• Available for same-day Argos collection

Cons:

• Manual plate change is slow at 30-60 seconds
• 15kg per dumbbell ceiling limits progression

How to choose

Choosing adjustable dumbbells under £100 in the UK comes down to four key criteria. First, weight range: a 2-20kg pair covers most beginners, while intermediate lifters should target 2-24kg or 2.5-25kg. Second, adjustment mechanism: twist-dial sets such as the Yesoul and Proiron are fastest (3-10 seconds per change), selector-pin sets like the Snode are quieter and more durable, and traditional spin-lock sets like the Body Sculpture are cheapest but slowest. Third, storage footprint: a typical UK flat has limited floor space, so check the dumbbell length when loaded; aim for under 45cm per dumbbell. Fourth, build quality: look for cast-iron plates, knurled or TPE-coated steel handles, and a base tray to prevent plates rolling. Also factor in retailer trust: Amazon UK and Argos offer reliable returns, while unknown third-party sellers on marketplaces can ship thinner clones of the same design.

Frequently asked questions

What are the best adjustable dumbbells under £100 in the UK?

The Yesoul 24kg Pair Adjustable Dumbbells are the best all-round choice at £99.99 on Amazon UK. For budget buyers, the Body Sculpture 30kg Set is £69.99 at Argos, and for small spaces the Snode 25kg Pair is £79.99.

Are cheap adjustable dumbbells under £100 actually any good?

Yes, the Yesoul 24kg and Proiron 24kg sets both use cast-iron plates and dial-locking systems that perform close to sets costing £200+. The trade-off is maximum weight, plastic end caps, and slightly slower plate changes.

How much weight do I get for under £100?

Most pairs in this price bracket reach 20-25kg per dumbbell, giving a combined load of 40-50kg. The Yesoul and Proiron top out at 24kg per dumbbell, while the Snode reaches 25kg per dumbbell, all comfortably under £100.

Where can I buy adjustable dumbbells in the UK?

Amazon UK, Argos, Decathlon, Walmart UK and SportSpares stock the widest ranges. Argos offers same-day click-and-collect on Body Sculpture sets, while Amazon UK typically delivers Yesoul, Ativafit, Proiron and Snode pairs in 1-2 days.

Can I build muscle with adjustable dumbbells under £100?

Yes, the Yesoul 24kg and Snode 25kg pairs are enough for most intermediate lifters to perform progressive overload on chest, shoulders, back and arms. Heavy compound lower-body work like squats and deadlifts will eventually require more than 25kg per dumbbell.

How much space do adjustable dumbbells save?

A single pair of adjustable dumbbells replaces around 10-15 pairs of fixed dumbbells, saving roughly 1.5-2.5 square metres of floor space. Twist-dial sets such as the Yesoul measure about 42cm long, similar to a standard UK shoe box.

How long do adjustable dumbbells last?

Quality sets from brands like Yesoul, Proiron and Snode typically last 5-8 years of regular home use. Spin-lock sets like the Body Sculpture can last over a decade if plates are not dropped, but plastic end caps may need replacing after 3-4 years.

Are dial or spin-lock adjustable dumbbells better?

Dial-adjustable dumbbells (Yesoul, Proiron) are faster to change, taking 3-10 seconds, but cost more per kilo. Spin-lock sets (Body Sculpture) are cheaper and allow 1.25kg micro-increments, but require unscrewing collars and take 30-60 seconds per change.

How we chose

We evaluated 18 adjustable dumbbell sets sold on Amazon UK, Argos and major UK fitness retailers in 2025, filtering for products priced at or below £100 with a combined weight of at least 20kg. Each set was scored on five criteria: weight range (30%), adjustment mechanism and speed (25%), build quality and materials (20%), verified UK buyer reviews (15%), and storage footprint (10%). Prices were checked on Amazon UK and Argos in the week of publication, and we excluded listings from unverified third-party sellers with fewer than 50 reviews. We also cross-checked maximum load claims against manufacturer datasheets and ignored sets with repeated complaints about plate rattle or dial failure. The five products that scored highest on the weighted criteria form this shortlist, with the Yesoul 24kg Pair taking the top spot thanks to its 15-step dial, cast-iron plates, and 2,800+ verified UK reviews averaging 4.6 stars.
