If I could only use one piece of fitness kit for the rest of my life, it would be the kettlebell. Why? Because its versatility knows no bounds, and it’s incredibly effective at making you faster, fitter and stronger.

“You can stick a kettlebell in the corner of any room in your house and you have a whole gym,” legendary kettlebell coach Dan John tells The Independent. “You can get your cardio work done, your mobility work done, your flexibility work done and increase your strength. It’s a one-stop shop for training.”

Newcomers to strength training can see incredible progress with just three beginner kettlebell exercises – the swing, goblet squat and Turkish get-up – while advanced lifters might build explosive moves like cleans and snatches into a challenging complex. Whatever your level, all you need is a kettlebell or two – that’s where I come in.

I’ve tested a selection of the best kettlebells on the market, from cast iron customers to competition-ready ‘bells and tech-heavy digital options, all in the name of helping you find one that fits your needs. Below, you can find a list of my favourites, and a brief breakdown of the perfect prospective buyer for each one.

How I tested the best kettlebells

Kettlebells are versatile by nature, so I tested them in a range of ways. Firstly, I used each one for what coach Dan John calls “the best single kettlebell workout” – a challenging cocktail of kettlebell swings, goblet squats and press-ups. Next, I used them for a selection of strength and muscle-building exercises such as squats, deadlifts, rows and overhead presses. And finally, I tried using them for a variety of loaded carries.

Beyond this, I also incorporated them into my weekly workout routine, using them for everything from leg-strengthening front rack Bulgarian split squats to the mobility-boosting windmill exercise.

The kettlebells that made it into this list showed good versatility, ergonomics and durability throughout these tests. They fitted comfortably into a front rack position (between the front of the shouler and the forearm), which is pivotal for many kettlebell exercises like overhead presses and cleans, and didn’t show signs of wear and tear from regular use.

The best kettlebells for 2025 are:

Wolverson competition kettlebells

  • Best: Overall
  • Why we love it
    • Standardised size and shape
    • Premium look and feel
    • Grippy handle
  • Take note
    • Expensive

Competition kettlebells are a cut above the rest. They’re uniform in size, whatever their weight, so you won’t find the handle too small or the bell too wide when performing swings. They also have a durable steel construction and are colour-coded depending on the load, which is helpful.

This Wolverson one is a prime example. The standardised shape felt great for exercises like cleans, snatches and overhead presses, nestling nicely into a front rack position, and the bell itself felt bulletproof.

The retro Wolverson branding makes it look about as cool as a kettlebell can, and there are weight options from 4kg to 32kg to suit a wide variety of lifters.

Domyos 12kg kettlebell

Domyos 12kg Kettlebell.jpg
  • Best: Budget buy
  • Why we love it
    • Good value for money
    • Rubber base protects floors
    • Robust design
  • Take note
    • Handle can feel too wide for swings on smaller bodies

Kettlebells aren’t cheap, but at £29.99 for a 12kg weight this Decathlon offering represents solid value for money. There are weight options from 4kg to 24kg, and it has a rubber base for protecting your floors while dampening the sound of it landing on the ground.

The wide, rectangular handle can easily be gripped with both hands, and the weight felt nicely distributed for explosive exercises like snatches. The handle on heavier weights was a little wide for smaller bodies when hinging it between the thighs during swings, but that was my only cause for concern.

BLK BOX cast iron kettlebell 2.0

BLK BOX Cast iron kettlebell 2.0
  • Best: Cast iron option
  • Why we love it
    • Durable
    • Wide range of colour-coded weight options
    • Textured finish for good grip
  • Take note
    • Metal finish can mark some floors

I’ve owned my BLK BOX cast iron kettlebell for years, and I don’t think I’ll ever have to buy another one. It’s survived umpteen house moves, home workouts and even spells spent in a damp shed, all with negligible signs of wear and tear.

The shape is great for any kettlebell exercise, the powder coated handle offers solid grip and small colour-coded bands around the handle let you know the weight you’re lifting.

Body Revolution neoprene cast iron kettlebells

Body Rev Neoprene Kettlebell.png
  • Best: For home workouts
  • Why we love it
    • Neoprene coating to protect floors
    • Robust build
    • Wide handle for double-handed exercises
  • Take note
    • shape of lighter weights doesn't fit well in front rack position

This kettlebell’s neoprene cover can protect both the bell and your floors, as well as dampening the noise when you dump it down – handy if you have wooden floors, or want to stay on speaking terms with a downstairs neighbour.

It didn’t leave any scuffs or dents in my home during testing, and the wide handle meant I could grip it comfortably for two-handed exercises like swings. The neoprene casing felt fairly robust too, while the cast iron innards are clearly built to last.

Lighter weight options manage to maintain the generous handle size fairly well, although the significantly smaller bells don’t fit brilliantly in a front rack position. But this was my only minor grumble.

Opti vinyl 2kg kettlebell

Opti 2kg kettlebell
  • Best: For beginners
  • Why we love it
    • Affordable
    • Pads on the base to protect floors
    • Easier on the hands than metal kettlebells
  • Take note
    • Plastic finish feels cheap
    • Limited, light weight options
    • Slightly awkward shape for some exercises

The lower weight options on offer (2kg to 10kg) and resulting lower price points make this a strong choice for newcomers to kettlebell training.

The vinyl finish feels cheaper than competition and cast iron kettlebells, but still works fine and proved durable over the testing period. Pads on the base protect your floor when you place it down, and a textured underside to the handle helped with grip during sweaty sessions. However, I felt the flat base didn’t offer ergonomics on par with curved-bottomed kettlebells.

Overall, it’s a good option for those looking to start kettlebell training, but experienced lifters will likely need a heavier, more traditional metal bell.

Pro Fitness 16kg kettlebell

Pro Fitness 16kg kettlebell
  • Best: Budget cast iron option
  • Why we love it
    • Very robust
    • Classic design
  • Take note
    • Glossy finish
    • Lighter weights have smaller bodies

This classic cast iron kettlebell is built to stand the test of time, with solid ergonomics and a reasonable price tag to boot. The metal bell may mark vinyl or wooden floors if you don’t use it with an exercise mat, but beyond that I had no complaints about its performance.

The handle offered good grip and plenty of room for double-handed exercises, and the shape was well-suited to swings and snatches as well as standard strength-boosting moves like bent-over rows.

I tend to opt for a matte finish rather than the glossy one Pro Fitness has plumped for, but that’s just a case of personal preference.

Jaxjox kettlebell connect

JAXJOX Kettlebell Connect.jpg
  • Best: For resistance training

This smart cookie packs six kettlebells into one compact package. The exterior is hollow, weighing roughly 5.5kg, then the inside houses a stack of 3kg weights which can be attached or unattached at the touch of a button on its docking tray. This means you can choose a load of 5.5kg, 8.5kg, 11kg, 13.5kg, 16.5kg or 19kg to suit the exercise you’re doing.

I found this was a good fit for standard resistance training exercises like rows and deadlifts, where I was holding the kettlebell by its handles. However, the large shape proved to be a bit cumbersome for dynamic moves like cleans and swings, as well as anything involving the front rack position like an overhead press.

The kettlebell launched for £249.99, in tandem with an app which could track your reps and provide follow-along workouts. But, with the demise of the app, you can now pick it up at Amazon for a fraction of this original price – it still functions just fine as an adjustable kettlebell.

Reebok 4kg kettlebell

Reebok 4kg kettlebell
  • Best: For durability

This diminutive kettlebell only comes in 4kg, 6kg and 8kg weight options, so it’s not one for those who like lifting heavy. But if you’re after a lighter kettlebell for introducing yourself to kettlebell training, it does a lot right.

The cast iron body is incredibly robust, and it has a dipped vinyl coating to prevent the kettlebell scuffing or marking hard floors. The handle is surprisingly wide for a lighter weight, allowing me to easily hold it with both hands, and the small body makes it easy to store away.

The weights aren’t uniform in size like a competition kettlebell, so the small bells feel a bit awkward in a front rack position. But it worked well for exercises like goblet squats, as I could grip it by the wide handles.

Kettlebell FAQs

How to use kettlebells for beginners 

Dan John is one of the world’s best-respected kettlebell coaches, and he believes most people can go a long way with just three foundational kettlebell exercises: the kettlebell swing, goblet squat and Turkish get-up. If you’re a beginner, you can swap the Turkish get-up for a press-up at first, as it can take a little while to learn the technique for this more technical move.

He also supports the concept of a minimum effective dose – the smallest amount of work you can do to achieve your desired goals, which in this case are improving strength and fitness. For the below exercises, he says the doses for most people are roughly 75-125 kettlebell swings, 15-25 goblet squats and 1-10 Turkish get-ups on each side of the body (or 15-25 press-ups) per workout.

  • Goblet squat: Stand with your feet roughly shoulder-width apart and your toes pointed slightly outward, holding a kettlebell tight to your chest with both hands. Keeping your chest up, push your hips back as if you were sitting down on a chair, then bend your knees to lower your hips towards the floor. Once your hip crease is lower than your knee, drive through your feet to return to the starting position.
  • Kettlebell swing: Assume a wide stance with your feet either side of a kettlebell on the ground in front of you. Keeping your spine long, hinge at the hips to bend over and grab the kettlebell with both hands using an overhand grip. With straight arms throughout, draw the kettlebell up and back between your thighs, then squeeze your glutes to powerfully send the kettlebell forward. When it reaches its apex, allow it to arc back between your thighs and repeat.
  • Turkish get-up: Lie on your back holding a kettlebell in your right hand with your arm extended towards the ceiling. Bend your right leg so your knee is pointing upwards and your foot is planted on the ground, toes forward. Sit up so you can prop yourself up on your left elbow, then raise your torso further so you can support yourself with your left arm straight, palm on the floor. Bring your left knee under your body to come into a lunge position, then stand up. Reverse this sequence to complete the repetition, then repeat on the other side.
  • Press-up: Start in a high plank position, with your weight spread between your toes and your hands. Your hands should be roughly under your shoulders, and your body should form a straight line from the back of your head to your heels. Keeping your core tight and your elbows tucked into your sides, bend your elbows to lower your chest towards the floor. When your toros is a couple of centimetres from the ground, push through your hands to return to the starting position. You can lower your knees or elevate your hands to make this exercise easier.

Weight

For strength training to be effective, you have to use a weight that isn’t so heavy that it forces your form to falter, but is heavy enough to challenge your body. A good litmus test for this is to find a weight you can press overhead 10 times. This should provide you with a mid-weight kettlebell you can use for a wide range of workouts.

Types of kettlebell

There are four main types of kettlebell, and each one has its ideal owner. I’ve done my best to outine these below:

  • Competition kettlebell: These free weights are for those who take their training seriously. Whatever the weight, they’re uniform in size and shape for consistent ergonomics. The wide, boxy handles offer plenty of room for a double-handed grasp, and the metal finish responds well to chalk for extra grip. They’re also colour-coded depending on their weight, although their quality craftsmanship usually comes at a price.
  • Cast iron kettlebell: This is the best type of kettlebell for most people because its seamless design is simple, robust and effective – I’ve had mine for years, and plan to use it for many more to come. The size will differ depending on the weight (the larger the bell, the heavier it is) and the handle might not be as grippy as a competition kettlebell. But these options tend to be cheaper, and can come with a rubber covering to protect your floor from scuffs.
  • Vinyl kettlebell: This is a good option for beginners. The plastic finish feels cheap, and they can often be filled with sand rather than metal, but that does cut the cost significantly. They only tend to come in lighter weight options, and ones I’ve tried in the past have had larger bells that can be cumbersome for some exercises. But they won’t mark your floors and can be more forgiving than metal alternatives when making contact with your wrists and shoulders.
  • Adjustable kettlebell: This is a new addition on the scene. Adjustable kettlebells tend to have plates or weighted pucks which can be attched or removed from a central bell to change the weight. This is great for strength-boosting exercises, although they’re odd shape and less secure feel means I’d rather have a classic kettlebell for explosive exercises and high-intensity workouts.

The verdict: Kettlebells

If you’re looking for a quality kettlebell that will last a lifetime, Wolverson’s competition kettlebell is in a league of their own. It’s a premium product with a surprisingly appealing retro aesthetic, but this does ramp up the cost.

If you’re after something more affordable while still offering excellent quality, a cast iron kettlebell is your best bet, and the bombproof BLK BOX cast iron kettlebell 2.0 is my pick of the bunch. Or, for beginners, the Opti kettlebell offers lighter weight options for less than a tenner.
