Adjustable Dumbbells

When 24kg stops being a challenge, most home lifters are stuck buying pair after pair of heavy fixed dumbbells. This 40kg adjustable dumbbell pair extends the useful life of two handles to seventeen settings each, covering everything from a light warm-up fly to a heavy incline press. It is supplied as a pair, two dumbbells, 80 kg in total.

KEY FEATURES

Supplied as a pair: two dumbbells, 40kg each, 80kg in total
17-in-1 weight selection up to 40kg per dumbbell
Replaces roughly seventeen pairs of fixed dumbbells
Built for heavy compound work: bench press, row, split squat
Quick-change selector supports drop sets and mechanical sets
Textured handle for grip security under load
Pairs with the Adjustable Dumbbell Stand for safe lift-height racking

PRODUCT OVERVIEW

Forty kilos per hand is a meaningful strength ceiling. For context, a lifter pressing a pair of 40kg dumbbells for repetitions is moving 80kg of free weight through an unstable, independently loaded path, which is a genuinely advanced dumbbell bench press. That headroom is why the 40kg pair is the version to buy if you have any intention of training seriously for more than a year.

The trade-off against the 24kg model is physical size and cost per pair. A 40kg selectorised bell is longer, which slightly narrows the range of motion available on close-grip work and makes the bottom of a deep dumbbell fly feel different. In exchange you never hit the wall that ends a 24kg dumbbell's usefulness, and you avoid buying a second set of heavy fixed bells later.

TRAINING APPLICATION

At this load the dumbbell stops being an accessory tool and becomes a primary one. Dumbbell bench press, single-arm rows, Bulgarian split squats, Romanian deadlifts and heavy shrugs all sit comfortably inside a 40kg-per-hand range. The independent loading also exposes and corrects left-right strength asymmetries that a barbell will happily hide, which is a real reason many coaches program dumbbell pressing alongside barbell work rather than instead of it.

HOW TO CHOOSE?

Buy the 40kg if you currently press 22kg or more per hand for sets of eight, or if you are pairing dumbbells with a bench and rack for a complete home setup. Buy the 24kg Adjustable Dumbbell if space is very tight, budget is the deciding factor, or you are early in training. For loads above 40kg per hand, a plate-loaded approach using an Olympic barbell and weight plates becomes more economical than any selectorised dumbbell.

FAQs

Is this one dumbbell or a pair?

A pair. Two dumbbells ship together, each adjustable to 40 kg, which is why the listing weighs 80 kg and why the price is pair money rather than the cost of a single bell.

Is 40kg per dumbbell realistic for home training?

Yes, and it is a level many trained lifters take years to reach on dumbbell bench press. It provides genuine long-term headroom rather than a number you outgrow.

Is it noticeably longer than the 24kg version?

It is, because the plates stack along the handle. This mainly affects very close-grip work and the deepest part of a dumbbell fly.

Can I use it for legs as well?

Certainly. Goblet squats, split squats and Romanian deadlifts all work well, though at some point loaded carries and squats will call for a barbell.

Questions & answers

What weights does the 40kg adjustable dumbbell cover?

The 40kg Adjustable Dumbbell has 17 settings up to 40 kg per dumbbell, selected with a quick dial while the bell sits in its cradle. One handle replaces roughly seventeen fixed dumbbell weights, and it is built for bench press, rows, split squats and Romanian deadlifts.

Is the 40kg adjustable dumbbell one dumbbell or a pair?

A pair. Two dumbbells ship together, each adjustable to 40 kg across 17 settings, which is why the listing weighs 80 kg. Buy one listing for both hands; call +44 191 743 7100 if you need anything confirmed before ordering.

24 kg or 40 kg adjustable: which one?

Buy the 40kg Adjustable Dumbbell if you already press 22 kg or more per hand for sets of eight, or plan to train seriously for more than a year. Buy the 24kg model if space is very tight, if budget decides, or if your heaviest dumbbell lift is under about 20 kg. Each model shows its current price on its own page.

How big is the 40kg adjustable dumbbell?

Each 40kg Adjustable Dumbbell is 45.5 cm long, 24 cm wide and 24 cm high at full load. It is longer than the 24 kg version because the plates stack along the handle, which the product page notes mainly affects very close-grip work and the bottom of a dumbbell fly.

Does the 40kg adjustable dumbbell include a stand?

No. The Adjustable Dumbbell Stand is sold separately. It is dimensioned for the 24 kg and 40 kg cradles sold by Lift Sets and holds a matched pair at lift height. Dial-style dumbbells from other brands use different tray widths and may not seat securely. The stand shows its price on its own page.

How much is delivery on the 40kg adjustable dumbbell?

Free delivery to every address in Great Britain, including the Scottish Highlands and Islands. The 40kg Adjustable Dumbbell is on the heavy-item profile, so Northern Ireland is priced by shipped weight at checkout on the heavy single box rate.
