Not sure which setup is right for you?
Take Our QuizAdjustable dumbbells are the single best investment for home training. One pair replaces 15+ fixed dumbbells, saves massive floor space, and handles almost any exercise you'd do with free weights.
Why Adjustable Over Fixed?
A set of fixed dumbbells from 5-25kg costs around £800 and needs 2+ metres of rack space. Quality adjustable dumbbells cost £200-400 and fit in a corner.
The maths is obvious. So is the practicality: adjustable dumbbells let you change weights in seconds between sets, making supersets and drop sets effortless.
NUOBELL: The Best Overall
The [NUOBELL Adjustable Dumbbells 2-24kg](https://www.amazon.co.uk/dp/B00A21NRNO?tag=homegymadvice-21) (£339) are what everyone's comparing against. The twist-dial mechanism is genius: turn the end and the weight changes. No pins, no plates to swap.
They feel like traditional dumbbells in your hand, unlike blocky alternatives, and the 2kg increments are ideal for progressive overload.
Pros: Instant weight changes, traditional dumbbell feel, sleek compact design Cons: Premium price, 24kg max may limit very strong users
MuscleSquad: Best for Small Spaces
The [MuscleSquad Adjustable Dumbbells 27.5kg](https://www.amazon.co.uk/dp/B0F5B4TNP2?tag=homegymadvice-21) (£189) pack serious weight into just 42cm length: among the most compact adjustable dumbbells available.
UK brand with proper customer service. The quick-change mechanism isn't as slick as NUOBELL but works reliably.
Pros: Most compact design, UK brand support, 27.5kg max weight Cons: Mechanism requires gentle handling, weight changes slower than twist-dial
PROIRON: Best Budget Option
The [PROIRON Adjustable Dumbbell Set 20kg](https://www.amazon.co.uk/dp/B094CXV7XL?tag=homegymadvice-21) (£64) proves you don't need to spend big to start strength training. Cast iron plates with spin-lock collars. Simple, robust, reliable.
The catch: weight changes take 30+ seconds. Fine for beginners, frustrating for serious trainers.
Pros: Unbeatable price, cast iron lasts forever, secure collars Cons: Slow weight changes, 20kg total may limit progression
Which Should You Buy?

Don't "swing" them up with momentum. It stresses the mechanism. Use controlled movements and you'll never have problems.
