Kettlebells are one versatile piece of equipment. A couple of swings in, and you’re sure to sweat buckets. It’s more so enticing to hoard different sizes in all the colors available. For serious kettlebell swingers, you could even join the club and be one of the athletes over at Kettlebell Sport. Yes, they exist!

Wonderful benefits aside, we can still agree that kettlebells are not the most space-saving workout equipment. They’re bulkier than dumbbells, plus they get bigger as they get heavier. 

Our modern-day solution? Adjustable kettlebells! They are more economical in the long run, and they also give you that sweet spot between the increments that feel satisfyingly heavy for a monumental swing or Turkish getup. 

Carrying the popular Bowflex SelectTech Barbell DNA, the Bowflex SelectTech 840 Kettlebells is one of the best adjustable kettlebells and carries a decent 8-40 pounds of weight with a quick selection in just a turn of a dial. It’s one of the slickest-looking kettlebells we highly recommend for its value, construction, and ease of adjustability. Let’s get to the full review.

Adjustability is one of the most important aspects of an adjustable kettlebell. Powerblock serves convenience to users by providing a smooth transition between different weight increments. Its metal pin mechanism is quite unique yet intuitive even for beginners.

Bowflex SelectTech 840 Kettlebell – Best Overall

What we like

  • Easily adjustable dial
  • Wide range of weights
  • High-quality weight markings
  • 24 trainer-led exercises

What we don’t like

  • The maximum weight is 40 lbs
  • Thinner handle compared with traditional kettlebells
  • The plastic material handle seems less durable

Kettlebell workouts are made more convenient with the Bowflex SelectTech 840 Kettlebell. It has sufficient weight settings from 8 lbs to 40 lbs, so you can go light or heavy anytime. It has a smooth dial that lets you adjust the weight increment smoothly, so you don’t have to fuss or fight with the unit. Choose among 8, 12, 20, 25, 35, or 40 lbs, switch the dial to your desired setting, and swing away! 

As with its function, it feels much like a traditional kettlebell, so there’s a very little adjustment period for anyone who eyes this unit. All in all, the Bowflex SelectTech 840 Kettlebell is the best one yet for laidback use. It replaces up to 6 kettlebells but stops at 40 lbs. as its maximum weight limit.

Powerblock Adjustable Kettlebell – Best Easy-Adjust

What we like

  • Secure, non-skid surface with powder-coated finish
  • Comes in two weight variations (16kg, 28kg)
  • Compact cowbell design compared with traditionally round kettlebells

What we don’t like

  • Limited weight range
  • Hefty price tag
  • Only four increments are available

The Powerblock Adjustable Kettlebell aims to replace up to 4 kettlebells in one. The top-tier gripping comfort on its handle is worth praising. Not every adjustable kettlebell gets it right. 

This one is made with solid steel construction, so you better believe that it feels strong, durable, and tight with every swing or snatch performed. At best, you can have 35 lbs at the maximum setting. This goes down to 26 lbs, 22 lbs, and 18 lbs. If you’re not quite happy with that, get the heavier variation at 28 kg or 62 lbs, max. 

Powerblock utilizes a steel selection pin with a magnetic lock. No flimsy stuff here, just pure simplicity and functionality. We also appreciate the properly marked digits, which show the weights in pounds and kilos. Whether you use the metric or imperial system, you can take the time-consuming conversion out of the equation.

Apex Adjustable Heavy Duty Kettlebell – Best Budget

What we like

  • Thick textured handle for workout comfort
  • Most affordable unit in the bunch
  • Great for beginners and simple kettlebell movements

What we don’t like

  • Weight plates are sold separately
  • Inefficient weight-adjustment system

Indeed, great adjustable kettlebells can come at affordable prices, just as the Apex Adjustable Heavy Duty Kettlebell proves.

The handle and bottom plate are made with a solid cast steel body with powder coating, each one weighing 15 lbs and 5 lbs each, respectively. Sandwiched in between are removable spacer discs that weigh 0 lbs. You can swap these with your desired weight plates with 1-inch diameter holes. The total weight limit is 50 lbs.

The U-bar handle allows the smooth performance of one-hand and two-hand workouts without your fingers cramming under the handle. The exterior surface of this adjustable kettlebell is textured and rough, perfect for scratch-proof and sweat-proof use. 

Our only gripe is that you need to own weight plates in order to maximize the weight capacity of this kettlebell. Otherwise, you’ll be left with a chunky 20-lbs kettlebell to work with.

The Original Kettle Gryp – Best Portable

What we like

  • Best for frequent travelers and on-field trainers
  • Innovative design for multipurpose fitness
  • Travel-friendly with a small size that fits in the gym bag
  • Compatible with an adjustable dumbbell
  • It offers a secure, tight fit of the dumbbell

What we don’t like

  • You need to own dumbbells
  • Odd weight distribution compared with traditional kettlebells
  • Doesn’t fit some neoprene coated dumbbells

The Original Kettle Gryp has a unique structure that functions as a kettlebell handle. Now how much weight you add would be entirely up to you. As far as the advertisement claims, this one can accommodate up to 55 lbs of dumbbells. For non-competitive and personal use, we’d say this weight cap is good enough. Keep in mind that it can lock in dumbbells that are 4.5 inches long or so.

Meanwhile, the combination of ABS plastic, urethane foam, and stainless steel creates a fusion of a textured surface with a soft feel. This is great for fitness enthusiasts who can’t be bothered with slippery handles. It’s also pretty rigid against impacts, scratches, and dents. The bold orange paint gives it a nice pop of color that you can easily spot in your pool of fitness equipment.

For more or less $35 apiece, you can easily buy 2 pieces to come up with a pair. The only downside here is if you don’t own dumbbells yet. Shopping for such can easily flush your money down the drain since purchasing individual free weight are more costly than otherwise.

Yes4All Rubber Base Cast Iron Adjustable Kettlebell Weight Set – Best Wide Grip

What we like

  • Comfortable and secure grip with slightly textured handle
  • Flat bottom for stability
  • Significantly wider handle to enable two-hand kettlebell movements

What we don’t like

  • Iron plates are not exactly 5 lbs each as advertised
  • Unmarked weight numbers

Whether you’re using adjustable kettlebells or a normal kettlebell, the handle can be quite a hit or miss. To address this common issue among kettlebell fitness enthusiasts, Yes4All went the extra mile to provide sturdy, strong, and lengthy handles on their adjustable kettlebells to provide comfort and convenience during 2-hand exercises.

There are 6 removable cast iron plates that are approximately 5 lbs each. You can remove them or keep them as it is to achieve your desired weight between 5 to 40 lbs. The handle itself gives a slightly textured feel which can be promising during sweaty kettlebell swing sessions. To remove or add cast iron plates, simply press and slide to unlock, remove/insert the plate, and press and slide back to lock.

Structure-wise, the flat bottom is particularly handy for kettlebell exercises that require a flat surface, including renegade rows, mounted pistol squats, and KB deadlifts. Considering everything, this saves you from purchasing multiple kettlebells all at once.

Exerbell Foldable and Adjustable Kettlebell – Best Foldable

What we like

  • Foldable design for space-saving storage and portability
  • Slip-free canvas handle
  • Sturdy dual-layer construction
  • Slim as a laptop when folded and weighs only 1lb.
  • Budget-friendly

What we don’t like

  • It may feel odd for users who are accustomed to steel kettlebells

The Exerbell Foldable and Adjustable Kettlebell offer a unique design that lets you work out anywhere, anytime, with a compact and portable unit. This is made with a fabric-coated exterior that gives off a modern design and an easy-clean bottom, while the cotton-canvas handle is easy to grip and looks premium.

Fill it up with water up to 10kg or 22lbs or with sand up to 14kg or 30lbs, roll up, attach the handle, and get to training! The weight markings are distinct and properly labeled, so there’s no confusion or any calculating necessary.

The integrated leak protection ensures no leakage whatsoever from the adjustable kettlebell. Even with playful dogs and children around, your Exerbell will remain intact, solid, and scratch-free. The colors are available in black, blue, gray, and sand.

ProsourceFit Adjustable Cast Iron Kettlebell – Best Versatile

What we like

  • Adjustable to seven kettlebells in one unit
  • Small weight increments to support gradual progression
  • Skid-free rubber bottom for safe use and stable storage

What we don’t like

  • It’s on the more costly end
  • The 28mm handle may be too narrow for users with bigger hands

By far, ProSourceFit has the most versatile settings to achieve the right weight for your workout. Comparable to Tru Grit Adjustable Kettlebell, this adjustable kettlebell is made with cast iron plates that you can remove anytime to suit your current strength level. Feel free to change the weight settings from 10 to 40 lbs in total. To operate, slide the handle open, slip in your preferred weight plates, and slide back in to lock in place. 

The cast-iron handle measures 28mm, so your forearms and hands have constant tension during your arm and core exercises. In fact, you can freely perform full-body workouts with the possible weight variations you can choose from. For stable and safe use each time, the bottom of this fitness adjustable kettlebell is made with a non-slip rubber base.

Nymph Code Adjustable Kettlebell – Best Lightweight

What we like

  • Dual handle mechanism with extra-wide two-grip top handle and side handles
  • Thick grip for safe handling
  • Smaller than other adjustable kettlebells
  • Multiple color options

What we don’t like

  • The plastic shell doesn’t feel sturdy for lifetime use

The Nymph Code Adjustable Kettlebell is like other adjustable kettlebells with a few upgrades for your convenience. There are 4 removable discs in 3.35 lbs each. You can switch among 5 lbs, 8 lbs, 12 lbs, and 15 lbs to achieve the weight you need for particular movements.

To change the weight, simply unscrew the lid, put or take away the iron piece, and tighten back the lid. This design takes away the complexity of calculating the weight you need or figuring out how the dial works. With its appearance, the Nymph Code Adjustable Kettlebell comes in popping colors of blue, orange, pink, and black.

JpoDream Adjustable Kettlebell – Best Space-Saving

What we like

  • More affordable than regular kettlebells or a full kettlebell set
  • Large handle and flat bottom for safe and stable workout sessions
  • Fun colors to choose from
  • Solid concrete material with vinyl finish

What we don’t like

  • Limited weight increments

The JpoDream Adjustable Kettlebell is made with solid concrete and painted with vinyl. If you ask us, this is a great material combination to combat corrosion and damage in the long run. These also make the adjustable kettlebell more durable and noise-free during workouts.

Furthermore, the flat base makes it a dream to perform exercises that require a flat surface, such as renegade rows, push-ups, mounted pistol squats, deadlifts, and such. Most importantly, you can trust the strong tabs to secure the weight discs in place at all times.

To change the weight, remove one or both discs to achieve 5 lbs., 8 lbs., 9 lbs., or 12 lbs. For reference, the top weight with the handle is 5 lbs., the middle disc is 3 lbs., and the bottom disc is 4 lbs. You’ll be guided with the large handles that feel comfortable and intuitive to hold.

Titan Fitness Adjustable Kettlebell – Best Multi Weight

What we like

  • Wide range of weights
  • Perfect for a budget home gym with full versatility
  • Excellent durability with a black powder-coated surface
  • Wide adjustable handle knob
  • The 38mm handle is ideal for users with large hands

What we don’t like

  • No marks on weight increments
  • A significantly thin handle with a slippery surface when sweaty

The Titan Fitness Adjustable Kettlebell is by far the best multiweight adjustable kettlebell on the list. Its six cast iron plates can assure you of different weight levels, so you can swiftly go from 10 lbs to 40 lbs without hurdles. All discs are held together with a heavy-duty plastic clamp, as does the quick-lock mechanism for a secure hold.

Titan Fitness gives you full freedom to tailor your workout and alter the weight to your specific needs by adding or removing plates as you desire. This makes this Titan Fitness Adjustable Kettlebell an excellent addition to your collection of fitness equipment. The handle is made with a black powder coating that extends to 38mm for an ultra-comfortable grip

Final Verdict

Adjustable kettlebells can feel like uncharted territory for lifters who’ve been accustomed to standard kettlebells all their training life. Weight capacity is one vital determining factor in purchasing adjustable kettlebells, alongside weight increments, range, and adjustability. The perfect handle is another story altogether. Lastly, there’s the question of material, size, and portability as a whole unit.

Among the adjustable kettlebells we reviewed, we find the Bowflex SelectTech 840 Kettlebell as the most worthy of them all. It can easily replace 6 kettlebell weight ranges in one entire kettlebell with a total weight capacity of 40 lbs., all under a reasonable price that justifies its benefits. Bowflex would surely make a great companion for your everyday kettlebell training.

Buying Guide: Finding The Best Adjustable Kettlebells

Material and Durability

The best adjustable kettlebell provides excellent shell material for long time use. In this case, a powder-coated cast iron shell is the way to go. Take note that adjustable kettlebells are a single piece of the unit with removable discs – either plastic or iron – so the material is a significant aspect to review.

Weight Range

Weight increment needs would vary from person to person. In the products we feature, the weight limit is 50 lbs. This is great for experienced lifters and even more for beginners, although it may not be enough for professional kettlebell athletes. Kettlebells are sold in both lbs and kgs, so be ready to convert when window shopping.

Size

The thing about kettlebells is that the heavier they are, the bigger they get. This means more footprint occupied. Kettlebells come in different shapes, such as round, cowbell, and attachable. This affects your storage system and working space in your home gym, so make sure to research your kettlebell diligently.

Handles

Handles may seem like an ignorable part of a kettlebell, but this makes or breaks your performance in kettlebell training. As a standard metric, a 28mm-handle width is ideal for individuals with small hands, while those with larger paws can get a better grip with 33 to 35mm handles. Also, make it a habit to inspect the material, as the handle will carry the brunt of the work during your kettlebell training.

Adjustability

Some kettlebells have an intuitive design that makes it easy to adjust weights. Some have an efficient lock and load system. While some take forever to figure out, the best adjustable kettlebell should allow you to transition from one weight to another using a smooth dial with an ergonomic handle to tow.

Frequently Asked Questions

An adjustable kettlebell can help you progress well into your kettlebell training while allowing you to save space inside your home gym. Adjustable kettlebells are definitely functional and practical for those who prefer having single adjustable equipment over an entire set. For more serious training, consider getting a competition-style adjustable kettlebell.

Yes, in fact, the Bowflex SelectTech 840 Kettlebell is our Editor’s Pick among all the products we featured. It feels just like a standard kettlebell with additional bells and whistles for easy dialing between the weights ranging from 8 lbs. to 40 lbs.

Kettlebell swings and other exercises mainly focus on these muscles: 

  • Glutes
  • Hamstrings
  • Spinal erector
  • Upper back

We advise determining the right adjustable kettlebell for you through your current fitness level, desired goals, and existing exercise program. Every individual has different strengths and goals, so these should be the major determining factors for the best kettlebell weight that works for you.
