Dumbbell Set With Rack: Sizes, Real Costs and What to Buy

A dumbbell set with rack is a bundle of fixed-weight pairs plus the stand that holds them, and for most UK buyers the sensible starting point is a rubber hex set running from 2.5kg to somewhere between 15kg and 25kg. Expect to pay roughly £2.25 to £3 for every kilo of total iron, rack included. The real decisions are which weight range, how big the jumps between pairs are, and whether the rack it ships with will actually suit your room. This guide covers the set as a whole; if you only need somewhere to put dumbbells you already own, our dumbbell rack guide goes through rack types, load ratings and floor protection in detail.

What the common bundles actually weigh

Listing titles tell you the lightest and heaviest pair. They rarely tell you the total, and the total is what sets the price, the delivery weight and whether your rack copes. Here's the arithmetic for the bundles you'll see most often, assuming 2.5kg steps unless stated.

Bundle	Pairs	Total weight	Notes
2.5 to 10kg	4	50kg	Starter range, outgrown quickly for legs
2.5 to 12.5kg	5	75kg	Common A-frame bundle
2.5 to 25kg (7 pairs, skips 12.5, 17.5, 22.5)	7	170kg	5kg gaps above 10kg
2.5 to 25kg (every 2.5kg)	10	275kg	Needs a 3-tier rack
5 to 30kg (every 5kg)	6	210kg	Big jumps, fewer pairs
5 to 30kg (every 2.5kg)	11	385kg	Close to a commercial rack

That last row surprises people. A full 5 to 30kg run in 2.5kg steps is nearly 400kg of iron, heavier than most home racks are rated for and far more than a typical bedroom floor should hold in one small patch without some thought.

Cost per kilo: the number that cuts through listings

Divide the price by the total weight and the bundles start to make sense. Three in-stock examples on Amazon UK when we checked:

• A NORTHERN 2.5 to 12.5kg hex set with a 5-tier A-frame rack: £169.99 for 75kg, so about £2.27 per kilo.
• An Extreme Fitness seven-pair set (2.5, 5, 7.5, 10, 15, 20 and 25kg) with a rack: £499.99 for 170kg, about £2.94 per kilo.
• A PhysKcal 1 to 5kg set of five pairs on a steel rack: £129.99 for 30kg, roughly £4.33 per kilo.

The pattern holds across most listings. Small sets look cheap but cost the most per kilo, because a rack costs about the same to make whether it holds 30kg or 150kg. Mid-sized sets usually give the best value. Very large sets climb again as brands move to heavier-gauge racks and better rubber.

As a rough budget, a 2.5 to 25kg set in every 2.5kg step (275kg) works out at somewhere around £620 to £810 at those per-kilo rates. That's an estimate from the per-kilo range, not a quoted price.

Which increments you'll outgrow first

Your legs get there first. Goblet squats, split squats and Romanian deadlifts use big muscles, and someone who trains them twice a week will often find the top bell of a 12.5kg set too light within a few months. Rows and chest presses follow. The light pairs, oddly, never become useless: 2.5kg to 7.5kg dumbbells stay in use for lateral raises, rear-delt work and rotator cuff exercises for years.

The bigger issue is the size of the jumps. The ACSM position stand on resistance training progression suggests adding roughly 2 to 10% to the load once you can beat your target reps by one or two (American College of Sports Medicine, 2009). Going from 10kg to 12.5kg is a 25% jump. Going from 10kg to 15kg, which is what the seven-pair sets ask of you, is 50%. You can bridge that with extra reps, slower tempo or pauses, but a set with no gaps in the middle of your working range will serve you better than one with an extra heavy pair you can't lift yet.

So when comparing two sets at similar prices, look at the pairs between 7.5kg and 20kg. That's where most adults do most of their work, and that's where skipped weights hurt.

A-frame, 2-tier or 3-tier: what comes in the box

The rack in a bundle is chosen to fit that set, which is fine on day one and a problem when you want to add a pair. Briefly:

A-frame (tree) racks come with sets of five or six pairs, usually up to 10kg or 12.5kg. They need about 60 x 35cm of floor and hold one pair per tier, so there's no room to grow. Add a 15kg pair and it lives on the floor.

2-tier racks suit six to ten pairs of light to mid-weight bells. They're often low, which means bending down for the heaviest ones on the bottom shelf.

3-tier racks ship with the bigger sets and typically measure about 90 to 100cm wide by 45 to 50cm deep. They're the only realistic option for anything above about 200kg in total, and the heavy pairs sit at a sensible height.

If you think you'll buy heavier pairs within a year, it can be cheaper to buy the dumbbells without a rack and choose a rack separately. Our rack guide covers how to size one, so we won't repeat it here.

Rubber hex, urethane or chrome?

Almost every UK set with rack under £700 uses rubber-coated hex dumbbells, and for good reason. The hex heads don't roll, the rubber protects floors and the cost per kilo is the lowest of the coated options. The trade-off is smell: new rubber off-gasses for a few weeks, which matters more in a spare bedroom than a garage. Our rubber dumbbells guide covers that in more depth, and the best hex dumbbells page compares individual sets.

Urethane costs noticeably more and rarely appears in rack bundles aimed at home users, but it barely smells and resists chipping. Chrome dumbbells mostly appear in small 1 to 10kg sets with a stand. They look tidy in a living room; they're also slippery when your hands sweat and clatter loudly on a hard floor, so they're best kept to light accessory work.

Set vs adjustable dumbbells: the maths

A decent 24kg pair of adjustable dumbbells starts around £150 to £200, and a 40kg pair runs about £270 to £370. A fixed set covering 2.5 to 25kg in full 2.5kg steps would cost several times that and take up a metre of wall. On money and space alone, adjustables win easily, which is why our adjustable dumbbells explainer recommends them for most single-person home gyms.

A fixed set earns its price in a few specific cases. Supersets and drop sets are instant because there's no dial to turn. Two people can train at once. And there's no mechanism to wear out, so a rubber hex set bought now will likely still work in 20 years and resell easily. If any of those matter to you, the extra outlay starts to look reasonable.

Delivery: the bit listings gloss over

A 170kg set arrives as 170kg. Couriers typically leave heavy parcels at the front door or kerbside, and you carry them in. Sets often ship in several boxes, sometimes with the rack separate, so check how many parcels the listing mentions and plan for the heaviest one to be awkward for one person. If your gym is upstairs, that's a lot of trips.

Check the floor too. Spreading a few hundred kilos across a 1m rack on a suspended timber floor is generally fine in a normal house, but put the rack against a wall and over a joist run where you can, and put a rubber mat underneath to stop the rack feet marking boards.

Two sets with rack worth considering

Both were in stock on Amazon UK when we checked on 1 November 2026. We picked them on range, gaps between pairs and price per kilo, not hands-on testing.

NORTHERN 2.5 to 12.5kg hex set with 5-tier A-frame rack. Five pairs, 75kg in total, at about £2.27 per kilo. It suits beginners and anyone training mostly upper body. Expect to outgrow the top pair for leg work fairly quickly, and remember the A-frame has no spare tier.

Extreme Fitness seven-pair hex set with storage rack. Pairs of 2.5, 5, 7.5, 10, 15, 20 and 25kg, 170kg in total, at roughly £2.94 per kilo. The top end is heavy enough for most people's lower-body work for a long time. The 5kg gaps above 10kg are the catch, as covered above, so you may want to add 12.5kg and 17.5kg pairs later.

The NHS recommends strength work covering all the major muscle groups on at least two days a week (NHS physical activity guidelines), and either of these covers that comfortably.
