Kettlebells UK: Which Type and Weight Should You Buy? (2026)

Choosing a kettlebell comes down to two questions: what it is made of, and how heavy it should be. Get the type right and the bell will last for years. Get the weight wrong and it either sits in a corner or makes good technique harder to learn.

The short answer: for most people, a cast iron or rubber-coated kettlebell with a smooth, bare handle is the safest first choice. Choose neoprene if floors or group classes matter more, and competition steel if you want identical sizing at every weight. The right starting weight depends on your strength, training experience, technique and the exercise. As one published reference, StrongFirst suggests 8, 12 and 16kg for a woman of average strength and 16 and 24kg for a man of average strength. Most people need two or three bells rather than one.

What type of kettlebell should you buy?

For most people, cast iron or rubber-coated cast iron with a smooth, bare handle. The main differences between types are grip, floor protection and whether the bell changes size as the weight goes up.

Competition bells are defined by their dimensions rather than their material: Jordan Fitness, for example, describes its competition range as “manufactured to competition standards for handle diameter and bell dimensions” (Jordan Fitness).

What weight kettlebell should a beginner start with?

It depends on four things: how strong you are now, how much lifting you have done, how well you can perform the movement, and which exercise the bell is for. Use published guidance as a starting point, then adjust to what you can control.

StrongFirst, the kettlebell training school, publishes these starting sets and advises that even stronger lifters should not go above them at first (StrongFirst).

Treat the table as a guide, not a rule. If you are new to training, returning after a long break, or still learning the swing, start lighter than the table suggests. A bell that is too heavy turns a hip-driven swing into a back-bending lift.

How can you tell if a kettlebell is the right weight?

Test it on the movement you will use it for. The right weight lets you finish every rep with the same form as the first, and still feels challenging by the last few. As a rough guide:

• Swings and deadlifts: you should be able to hinge at the hips with a flat back for 10 or more reps. If your back rounds or the bell pulls you forward, go lighter.
• Goblet squats: you should reach full depth with your chest up for 8 or more reps.
• Overhead presses: you should be able to press strictly, without leaning back, for around 5 reps on each arm. Expect this bell to be one or two steps lighter than your swing bell.
• Turkish get-ups: start much lighter, often with no weight, until each step is controlled.

If you can, book a session with a qualified coach to learn the swing and get-up before buying heavier bells. Good technique matters more than the number on the bell.

How many kettlebells do you need?

Two or three for one person, and a full range for a studio or a household that trains together. One bell is rarely enough, because a weight that suits a press is usually too light for a swing.

A practical order to buy in: your pressing bell, then your swinging bell, then a bell one step above your pressing bell so you have somewhere to progress. Add a second bell at a working weight later if you want double front squats, double cleans or heavy carries.

At current prices, StrongFirst's starting sets cost £157 – £246 in JORDAN Neoprene singles: 8, 12 and 16kg come to £157, 16 and 24kg to £176, and 24 and 32kg to £246. The same 8, 12 and 16kg in Chrome/Rubber cost £190.

Why do kettlebells jump in 4kg steps, and does it matter?

Because that is the traditional progression, and it matters most for pressing. Many ranges run 8, 12, 16, 20, 24kg and upwards, so each step is the same 4kg in absolute terms but a very different jump in relative terms.

Swings and squats usually cope with these jumps because the hips and legs are strong. Overhead presses, Turkish get-ups and single-arm work often do not.

There are two fixes. Choose a range with 2kg steps where you need them, such as JORDAN Chrome/Rubber bells at 4–20kg. Or stay on one bell longer and add reps before moving up.

What should you check before buying a kettlebell?

Five details separate a bell you will use for years from one you will replace.

• Handle finish: smooth enough to rotate in the hand, without sharp seams or flaking paint.
• Handle window: wide enough to fit both hands for two-handed swings and goblet squats.
• Base: flat, so the bell stands upright for storage and floor exercises.
• Construction: one-piece cast iron or a solid core, with no welded joint between handle and bell.
• Range: the weights you will need next, in steps small enough for your pressing.

Are kettlebells worth it for strength and fitness?

Yes, for strength, posture and general conditioning; less so as your only cardio. The NHS physical activity guidelines ask adults to do strengthening activities that work all the major muscle groups on at least 2 days a week, and a swing, goblet squat and press between them cover legs, hips, back, core, shoulders and arms.

The trial evidence is encouraging. In a randomised controlled trial of 40 adults in jobs with high rates of musculoskeletal pain, eight weeks of kettlebell training three times a week reduced neck and shoulder pain by 2.1 points and low back pain by 1.4 points against a control group, and improved trunk extensor strength (Jay et al., Scandinavian Journal of Work, Environment & Health, 2011).

The same trial found no change in aerobic fitness. Pair kettlebells with a rower, bike or treadmill rather than expecting them to replace one; our home cardio machine guide covers the options.

What floor and storage do kettlebells need?

Rubber flooring where the bells are set down, and a rack once you own more than four or five. A dropped cast iron bell can crack tiles and dent timber, and bells left on the floor are easy to trip over.

A coated bell reduces floor damage but does not remove the need for matting. Our UK gym flooring guide covers thickness and where to lay it.

For storage, a two-tier rack is the tidiest option. The JORDAN Kettlebell Storage Rack, for example, holds up to 12 bells and measures 782mm high, 1,395mm long and 600mm deep (Jordan Fitness), a footprint of about 0.84m².

Where do kettlebells fit in a home gym or studio?

Early. Two or three kettlebells train the whole body in very little space: the bells themselves fit in a corner, and even a full set on a two-tier rack takes under a square metre of floor.

In a home gym they sit alongside a bench and a set of dumbbells; our UK dumbbell guide explains how the two overlap. For tight rooms, see our small-space home gym guide.

For sessions to use them in, our functional training guide and one-hour full-body workout both build around kettlebell movements.

Frequently asked questions

Is a 16kg kettlebell too heavy for a beginner? It depends on the person and the exercise. StrongFirst lists 16kg as a starting weight for a man of average strength, mainly for swings, squats and deadlifts, and as the heaviest of a first set of 8, 12 and 16kg for a woman of average strength. Most beginners will find it too heavy to press overhead at first, so pair it with a lighter pressing bell.

Should I buy an adjustable kettlebell instead? They save space, but the shape and balance can change as you add weight, and some designs rattle during swings. Fixed bells feel the same every rep. If space is the worry, two or three fixed bells on a rack take up less room than most people expect.

Are neoprene kettlebells good for swings? Yes. The cover is on the bell, not the grip, so swings, goblet squats and deadlifts feel normal and the coating protects floors. For high-rep cleans and snatches, many lifters prefer a bare chrome or iron handle that rotates more freely in the hand.

Do I need a competition kettlebell? Not to train well, but they suit more people than competitors. Competition bells keep the same handle and dimensions at every weight, which helps anyone who wants their technique to carry over as they move up. They cost more, so for general strength work a cast iron or coated bell does the job for less.

How quickly will I outgrow my first kettlebell? On swings, often sooner than on presses, which is why a heavier second bell is worth having early. On presses and get-ups, progress is slower, and a 2kg step between bells can make a real difference. Move up when the current bell feels controlled for every rep of your planned sets.

Can I use kettlebells on an upstairs floor? Yes for normal training, with rubber matting underneath. Avoid dropping bells, and keep heavy ballistic work such as high-rep swings to a ground floor where possible. A full set is a concentrated load on a rack, so have a suspended floor checked before you store a heavy set upstairs.

Which kettlebell should you buy first?

A smooth-handled cast iron or rubber-coated bell at a weight you can press with good form, plus a heavier one for swings. Use the StrongFirst table as a guide, test each bell on the movement it is for, and add a third when the first starts to feel easy.
