The best kettlebells 2024: for weightlifting, home workouts and gym

The best kettlebells are so versatile they should really be part of everyone's training routine. Whether you're new to strength training or a seasoned lifter, kettlebell workouts are a brilliant way to improve strength and conditioning, and having access to one at home means you can easily perfect technical kettlebell skills like snatches, cleans and swings. 

Whether you prefer adjustable kettlebells or standard ones, you'll want the most from your budget and investment. We've tried and tested the best kettlebells currently on the market from leading brands worldwide, housed each kettlebell for over six months, and tested them against criteria such as usability, budget, durability and the ability to use them during strength programs, CrossFit, cardio and hybrid workouts. 

Only then did we add them to our cast iron round-up of models to recommend. Unsurprisingly, our most-used and loved Bowflex SelectTech kettlebell came out on top, but it's worth noting that Bowflex has filed for bankruptcy recently, so while you might pick up a fantastic deal, it's worth reading up on whether it's worth investing.

Research from the Journal of Human Kinetics shows kettlebells are great additions to functional resistance and strength programs, building neuromuscular power, full-body strength, core stability, balance, coordination and more. Plus, they're just great fun to exercise with. The current boom in the kettlebell market means choosing the right model can feel confusing. That's where we come in.

The quick list

Here are the best kettlebells you can buy right now based on our testing. Scroll down for in-depth reviews.

Best kettlebell overall

This 6-in-1 adjustable kettlebell ranges between 8-40lbs and features a turn dial for six on-the-go adjustments. The Bowflex SelectTech is the most versatile and storage-friendly model we’ve tested, so we could switch quickly between upper and lower-body workouts, strength training, and cardio without messing around with plates — all you have to do is place the weight in the tray and turn the dial. 

Each purchase comes with a JRNY Mobile-Only two-month membership, giving you access to motion tracking, exclusive trainer-led workouts, and exercise content via the on-demand library on the Bowflex SelectTech app. 

We’ve been testing the Bowflex for months, and the ergonomic handle is a top feature for easy swinging and lifting. The smooth composite material also makes cleans and goblet holds easier on your arms and hands. Still, the bell and handle get sweaty and harder to hold, so we recommend using grip gloves if you plan to swing overhead or try more technical exercises. 

It’s chunky and somewhat cumbersome, but if you’re short on space and looking for a 6-in-1 solution, you can’t go wrong with the Bowflex, and it’ll save you a fortune too. 

Best kettlebell budget buy

Get back to basics with the Amazon Basics’ cast-iron kettlebell. If you’re new to kettlebell training, on a budget, or just need convenience, this kettlebell is worth every dollar. 

You’ve got a vast range of weights to choose from, and although they’re non-adjustable, the palatable price means you could buy more than one for your home gym, and the cast-iron design makes these kettlebells built to last. 

We needed chalk during testing, as the painted surface protects against corrosion but makes the bell slippy during weight training. The wide textured loop handle should add some grip and supports two-handed movements like kettlebell swings, and the base supports floor movements like renegade rows. 

This model is backed by an Amazon Basics limited one-year warranty, so there’s no need to worry if it's not the one for you. 

Best kettlebell for technical skill training

The iconic Spartanbell kettlebell from Gravity Fitness features Gravity’s exclusive Spartan design, crafted from cast iron to be seriously durable and robust. 

Aesthetically, this kettlebell can do no wrong, and it’ll see you through heavy weightlifting, technical lifts, bodybuilding, CrossFit and most strenuous workouts. Plus, it looks awesome. But you’ll need to have mastered technical skills like cleans and snatches before buying one. 

The design of the superbly crafted bell means it isn’t smooth or rounded, so banging this model against body parts could leave you with bruises if you’re new to technical lifts or fall victim to the foream slap. During testing, we had a few scrapes when lifting for high reps and sets, knocking the bell against arms or legs. 

That said, the Spartanbell has a competition-standard consistent handle thickness that we found easy to grip during workouts, and it’s compact with a very stable and wide base, stowing away easily and taking up little space in your home. You'll just need to get adjusted to the irregular shape. 

And if you’re not convinced, the model comes with a lifetime warranty to sweeten the deal. We've already noticed some chips and scuffs, but we haven't gone easy on this bell during testing. 

Best kettlebell for CrossFit and Hybrid workouts

Bulldog Gear’s Box kettlebells top the charts across most buying guides for the most versatile kettlebells on the market, and we agree. During testing, this kettlebell marked well against pretty much all of our criteria, ticking boxes for CrossFit-style workouts, strength and cardio training. 

With a weight range spanning 4-40kg, there’s something for all abilities. We tested the 16kg/ 36lbs, meaning we could switch between upper and lower body workouts easily and test most exercises. You get plenty of tacky grip on this model due to the matte black finish, but chalk holds well on the bell if you prefer using it. 

The box kettlebell range includes sturdy, durable bells with a great size base for lifting from the ground. Each model also has a color-coded band on the handles to quickly spot and change weights during workouts and an embossed weight identification in lbs/kgs. This model should be a staple in any home gym or hybrid class setting and it’s one of our top recommendations for best kettlebells on the market., but it's worth noting the bell scuffs and chips easily.

Best kettlebell for home gym

ONNIT Primal bells have been adopted and endorsed by pro athletes like AJ Hawk and Adam Dowell and described by some users as “functional art.” Aesthetically, these animal-inspired bells look slick and mean. Put them to the test and they stand up as some of the best kettlebells out there — durable, hardy and reliable, and capable of tackling any workout. 

The Primal range is made from chip-resistant iron with large handles to enhance grip during sweaty workouts and technical lifts. Each bell in the Primal range comes in a different weight. We tested the Chimp Primal Bell, but Howler weighs 18 lbs, and Bigfoot comes in at a hefty 90 lbs. 

This bell stood its ground during testing but we found it slightly cumbersome to hold because of its shape, and you'll need chalk to secure your grip. We also recommend a passable level of technical skill and forearm and wrist strength to avoid hitting the jagged edges against you during exercises like cleans. And we recommend taking your best fitness trackers off beforehand for this very reason.  

If you've never used kettlebells, Primal bells are still popular with beginners, but we recommend other, more forgiving, models in this line-up, as you don't want to experience the dreaded KB forearm slap with these bad boys.

Best kettlebell for high tech

Welcome to the future. The 6-in-1 digital adjustable kettlebell ranges from 12-42lbs/ 5.5-19kg and includes features like real-time performance tracking and advanced motion sensors. 

Connecting with the JAXJOX App is fast and easy, which gives you access to track accurate reps, sets, volume and power during exercise, and your purchase includes a 30-day free trial of the app for on-demand workouts and FitnessIQ tracking. 

The KettlebellConnect’s bullet-stacking system uses a rotating weight-selection core, so we could adjust on the fly in seconds in small increments during testing, perfect for switching between strength training and cardio or upper and lower-body workouts. And most importantly, it actually works well. 

If the tech hasn’t gone far enough, this model uses a machine-learning algorithm to generate a FitnessIQ. AI, stop reading my brain. It measures heart rate, steps and workout consistency as part of the calculation to track progress, and six-axis motion sensors to help monitor movement. 

Despite its high-spec credentials, on a practical level, this kettlebell is seriously bulky, and more technical moves were trickier due to the sheer size of the bell. Taller users might not find this an issue, but our tester, standing at 5”2, measured the bell sitting from wrist to elbow during overhead exercises.

But it charges quickly and saves space on the equivalent of six kettlebells. If you’re looking for real-time metric tracking and progress reports, it’s the perfect match.

Best kettlebell for competition

Wolverston Fitness competition kettlebells are suited to any strength training or functional training workout like CrossFit purely because they perform to last. 

These bells are consistently sized and colored to reflect their weight class so you can switch up and down quickly during workouts. The bells were designed by Girevoy athletes and calibrated for competition, using high-grade iron and a hollow core to maximize performance and reduce kettle rattle. 

During testing, we loved the wide flat base, which offers more stability than other models of its peerage, and it proved one of the easiest and grippiest to use during CrossFit. The stainless steel handle gave us plenty of room to grip during multitudes of kettlebell exercises due to increased handle clearance, and it responds well to chalk for sweatier workouts. 

The dimensions of the bells are uniform, allowing better consistency across all exercises, but the handle design can be altered to fit competition rules. The uniform size might bug you if you're only lifting light weights, but if you’re hoping to develop your technique on the bell or train for kettlebell competitions — it’s a perfect fit. You can even buy single or dual, depending on your needs.

Best kettlebell for grip

TRX rubber coated kettlebells are the grippiest we tested. The kettlebell has been constructed with a durable rubber coating on the bell and a powder-coated, textured cast-iron handle for better grip, maintaining a smooth finish while resisting scuffs and dirt during workouts. 

We swung, cleaned and pressed this bell through its paces during various functional workouts, and it came out on top every time with minimal scuffs to speak of. The sturdy flat base provides grounding when lifting from the floor, and the bell adapts well to strength and cardio workouts. 

If you plan to buy several kettlebells, TRX uses international color-coded weight rings to help you identify what you need during workouts, and each bell comes marked in lbs and kgs for easy identification. You can also access a 14-day free trial to the TRX Training Club App with your purchase. 

How to choose the best kettlebell for you

If you’re new to kettlebell training, it can feel like a minefield shopping for them. Below, we answer the most common questions to help you choose the best kettlebell for you. 

We also reached out to the masters of kettlebells, the Kettlebell Kings, and asked for honest opinions. "I've found that most of my clients and athletes will develop technique and strength faster with a higher quality bell," says Mike Silverman, who is a Living.Fit kettlebell master coach and the lead coach of the Tough Temple Kettlebell Club in Bethesda, MD. 

"Subtle things like window sizes, smoothness of the brand imprints on the metal, and finish quality on the handles really make for a better lifting experience. The top reason rookies quit is pain, especially in those with thin arms. A pointy bell hurts your forearms, a bell with crappy handles beats up your hands, and sharp logos are hard to rack pain-free." Here are some other things to look out for.

Adjustable vs fixed kettlebells

“Traditional” kettlebells are our favorites for building strength and developing the kettlebell technique. Typically, they are made from steel or cast iron and are extremely durable, sometimes with powder or vinyl coating. These models also vary in handle style, bell size and weight availability. Some might also have a special matte coating to enhance grip, while others (competition kettlebells) are standardized specifically for kettlebell competitions. 

The best adjustable kettlebells are a solid investment if you can afford the initial price tag and prefer having various weights available. A turn dial or button to change weights is handy, but they usually have a less durable design, a slippery plastic outer shell and come in much bigger sizes that aren’t standardized; this can make certain exercises harder to do, and it’s unlikely you’ll be able to perform some exercises using two.

Silverman adds, "While the adjustable bells are convenient, I greatly prefer a standard weight bell. Most of the adjustable kettlebells I've tried either rattle over time or feel somewhat off balance to me." He adds, "There's also the question of durability over time...I've never had a chunk of metal loosen up or wear out, but I've had more than my share of adjusting systems and screws fail. Nothing wrong with an adjustable bell, but for me, it's solid steel and magnetic chips if I'm going between sizes."

Competition vs cast iron kettlebells

Competition or “sport” kettlebells are standardized and color-coded to meet particular competition regulations, so whatever weight you use, the kettlebell will land the same way during the same exercises. 

The handles are generally 33 and 35mm in diameter with a squarer window to improve grip during endurance events and high reps and sets. If you don’t compete and have large hands, you might struggle to use competition bells during two-handed exercises, which is why they’re well-suited to single-arm exercises. 

And they’re bulky, so unless you complete and want to develop consistent technique across kettlebell exercises, you don’t necessarily “need” a competition kettlebell. But the stable base is helpful, whereas cast iron model bases can get smaller with decreases in weight.

Competition bells are often made from durable steel, but our top pick — the Wolverston Fitness competition kettlebell — uses high-grade iron and solid one-piece casting with a hollow core. They also produce Wolverston GS Competition kettlebells specifically for Girevoy Sport (a kettlebell endurance sport). 

Cast iron kettlebells are produced using a solid piece of metal and often increase in size with their weight. Typically, the handles are more spacious but less grippy, and you can hold two more comfortably than competition kettlebells. They feature at most gyms and CrossFit studios as the most versatile options.

"I'm a competition kind of boy, but each has its place," Silverman says. "Competition bells are standard sizes, meaning regardless of the weight the handle and bell stay the same. You can grab an 8kg or a 40kg kettlebell and it's the same size. That really helps your technique stay consistent." 

He adds, "Comp bells, because they're fairly big, distribute pressure across your forearms evenly so they don't hurt like smaller cast bells tend to do. Being wider and flatter, comp bells are safer and more versatile for things like pushups and daggers, unless you're into having a bell flip and smacking your knuckles into the floor."

Powder vs vinyl vs rubber coating kettlebells

Some kettlebells have a powder or vinyl coating for extra protection and grip. We find that powder coating holds chalk well, but rubber coating is also seriously grippy. It can be a personal preference.
