Kettlebells are a versatile tool that can be used for all sorts of training. Whether your goal is to build strength, develop explosive power, or improve your cardiovascular fitness, a high-quality kettlebell can get the job done.
However, there’s just one problem—having multiple kettlebells can take up quite a bit of real estate. From traditional pin-and-plate systems to modern dial-based designs, the best adjustable kettlebells allow for fast, frustration-free transitions that minimize disruptions or delays during your workout, all while keeping your floor plan neat and tidy without excessive free weights.
In this PowerBlock Adjustable Kettlebell review, we’ll take a look at one of the most popular options on the market and help you decide if it’s worth adding to your strength training arsenal. We’ve been impressed by the PowerBlock Pro 100 EXP Dumbbells, so let’s see if the brand’s engineering team designed another adjustable winner.
Our PowerBlock Adjustable Kettlebell Review, Summarized
The PowerBlock Adjustable Kettlebell offers home gym owners a unique, compact strength training solution that replaces four traditional kettlebells in a single silhouette. Available in two different sizes, you can quickly make weight changes using a magnetic steel selection pin system that proved to be a breeze during testing. Earning high marks across the board, we were particularly impressed by the construction and handle design—both of which received perfect scores from our expert product tester. The only caveat: This is not the most budget-friendly option, though we still think it provides rock-solid value.
How We Test Adjustable Kettlebells
Adjustment speed determines whether a kettlebell is practical for circuits or supersets, so we evaluate how quickly and easily each mechanism toggles across the given weight range.
A model that uses a selector pin or requires manual changes will earn a 3 out of 5 on our scale. We assign higher scores to ‘bells that use a fast dial, lever, or magnetic system that lets you change weights seamlessly without haste or hesitation.
A robust weight range gives you tremendous versatility and can help save money and space. We measure how many traditional kettlebells one adjustable unit can replace, with our testers looking for models that accommodate both beginner and advanced lifters with enough flexibility for progressive overload. A 3-out-of-5 score reflects a moderate range (roughly 8 to 35 lbs or 8 to 16 kg), while a 4 or 5 means a particular profile can replace a full rack of bells without sacrificing feel or functionality.
How useful is a kettlebell if you can’t keep a firm grasp on it during your training session? When assessing a kettlebell handle, we consider the diameter, grip performance (with and without chalk), and how well you can control the weight during long sets where sweaty palms may become problematic. To meet our scoring threshold for a 3 out of 5, the kettlebell must have a comfortable, controllable handle, but grip may begin to loosen with sweatier palms.
Over the years, we have developed a comprehensive kettlebell testing methodology that includes specific criteria for both traditional and adjustable kettlebells. For all ‘bells, we carefully evaluate categories such as construction, durability, handle, shape, and value. Adjustable profiles get scrutinized for adjustment speed and weight range. Our expert product testers put every kettlebell through a series of kettlebell exercises—including snatches, swings, Turkish get-ups, and goblet squats—to provide accurate ratings based on a 1-5 scoring scale.
The Garage Gym Reviews team includes certified personal trainers, CrossFit competitors, Olympic-level athletes, and strength training enthusiasts who understand and appreciate how small design nuances can make a major difference with your kettlebell training experience. Whether it’s standard kettlebells, competition ‘bells, or fully adjustable kettlebells, our team has tested more than 30 of these popular free weights over the years (with even more to come).
In 2025, we helped more than 1,300 athletes and home gym owners find their ideal ‘bell, and we’re ready to help connect you with the right one, too.
The PowerBlock Adjustable Kettlebell delivers a compact footprint and quick adjustments, making it a great pick for tight training spaces. The brand offers this bell in 35-pound and 62-pound totals, too, giving you some options in terms of your working weight range.
What to Know Before You Buy
- This kettlebell is available in two options, both of which have four different weight increments that you change with a magnetic pin. With such a large range of available weights, beginner and intermediate lifters should be able to comfortably use this kettlebell, though advanced lifters may need something heavier.
- Early iterations of this kettlebell had stickers displaying the weight increments that, in our experience, had a tendency to peel off easily. However, PowerBlock updated the design with embossed weight indications that alleviate this concern.
- The PowerBlock Adjustable Kettlebell features a unique, narrow design that’s more reminiscent of a cowbell than a traditional kettlebell. While this can be great for saving space, it also means the kettlebell shape feels a bit different in use, which may not suit all users.
- Although these kettlebells aren’t cheap, PowerBlock provides a 5-year warranty for added value and peace of mind. This is far superior compared to what most manufacturers offer, which is usually around 1 year of coverage.
Is the PowerBlock Adjustable Kettlebell Worth It?
With a cost that ranges from $199 to $349 (depending on the weight you need), this kettlebell isn’t the cheapest adjustable kettlebell on the market. Using the PowerBlock Adjustable Kettlebell doesn’t feel exactly like a traditional kettlebell, either, due to its cowbell-like shape. That said, we still think this is a durable kettlebell option that would likely fit well in many home gyms.
Our expert product tester enjoyed using this unique profile and said he’d personally keep it in his home gym, but that doesn’t mean it’s a perfect fit for everyone. Ultimately, this comes down to a matter of personal preference in terms of shape and adjustment mechanism. Below, we’ve listed some groups we think could benefit from the PowerBlock Adjustable Kettlebell, along with some parties that may fare better with an adjustable profile of a different make and profile.

Workout Experience with the PowerBlock Adjustable Kettlebell
Our expert product tester trained with the PowerBlock Adjustable Kettlebell for approximately one week, using it for a variety of exercises, including kettlebell swings, overhead presses, cleans, side lateral raises, squats, rows, and single-arm shrugs. When it comes to adjustable kettlebells, the most important factors for daily use are how the adjustment mechanism works, how the grip feels, and how the overall kettlebell feels, especially with a non-traditional shape.
Luckily, the PowerBlock Adjustable Kettlebell performed well in all of these critical areas. From the simple pin adjustment system to the comfortable handle, this profile proved worthy of its above-average price point with performances aligned with other top adjustable kettlebells we’ve examined.
Let’s dive into our expert product tester’s full training experience, so you can get direct insight.
I personally would have these as an addition to my home gym. Their functionality for training was excellent. In addition, being able to basically tuck four larger-sized kettlebells that normally would take up almost 3 square feet of floor space down to one kettlebell in about half a square foot is a no-brainer for me.”

PowerBlock Adjustable Kettlebell Rating
Construction
The PowerBlock Adjustable Kettlebell is made of durable alloy steel with a solid powder-coated grip, earning a perfect 5-out-of-5 rating for construction. The weight increments are marked in pounds on one side and kilograms on the other, with bright labeling and color-coding to help you clearly find the proper weight. This user-friendly feature allows you to stay focused on your workout instead of trying to figure out weight conversions.
It’s worth noting, too, that this kettlebell comes in two sizes: 18 to 35 pounds and 35 to 62 pounds. The dimensions are very similar, though the large weight range is slightly wider (as you’d expect). The smaller kettlebell is 4.25 inches wide by 5.75 inches long by 10 inches high, while the large option is sized at 5.39 inches wide by 9.06 inches long by 11.1 inches high.
No matter which ‘bell you choose, you can expect an ultra-compact profile that makes either profile a great fit if you’re tight on space.

Durability
Similar to other models we’ve tested, the PowerBlock Adjustable Kettlebell earned a rock-solid 4-out-of-5 durability rating. The solid steel construction should give you plenty of confidence in its structural integrity. Meanwhile, the powder coat finish further enhances the durability by serving as a protective barrier against rust and corrosion.
“The exterior coating is smooth, but not slick,” adds our expert product tester. “It has a texture similar to traction tape for floors.”
We also appreciate that PowerBlock uses a heavy-duty magnetic pin for secure weight selection. This should quell any concerns about the selection system breaking down over time, which would essentially render your adjustable kettlebell useless.
Adjustment Speed
Nobody wants to spend time struggling to change weights mid-workout. Thankfully, the PowerBlock Adjustable Kettlebell shouldn’t cause you any frustrations, according to our tester.
“Adjustments were a breeze when changing weight between sets or exercises for circuit training,” they note. “The pin handle is accessible without being obtrusive to its use.”
Earning a 3-out-of-5 rating for adjustment speed, the kettlebell’s pin felt “very secure” once in place, and our tester didn’t feel like it was at risk of falling out during training. To make the adjustment process even more user-friendly, PowerBlock smartly designed this kettlebell with color-coded pin holes to make weight selection much easier.
This system is far simpler to use than something like the Ironmaster Quick-Lock Adjustable Kettlebell Handle, where you have to add or remove weight plates to achieve your desired working total. However, this PowerBlock profile earns a middle-of-the-road rating in this category. It’s not quite as streamlined as the quick-dial adjustment systems of other adjustable kettlebells out there. “It’s not as quick to change as, say, Bowflex, but it works well,” adds GGR founder Coop Mitchell.

Weight Range
As mentioned earlier, there are two sizes available, so you can choose the kettlebell weight range that will suit your training needs best. The smaller version ranges from 18 to 35 pounds, allowing you to choose between 18, 22, 26, and 35 pounds, or 8.18, 10, 12, or 15 kilograms. This should work well for beginners who need to build a requisite level of strength before making the leap to heavier weights.
Meanwhile, the larger option ranges from 35 to 62 pounds with selectable weights of 35, 44, 53, or 62 pounds (16, 20, 24, or 28 kilograms). Both sizes have the weights clearly marked in both pounds and kilograms, which can be helpful for quick identification as you’re rapidly cycling through some kettlebell HIIT workouts.
Given the 4-in-1 design as well as the available weight totals at play across the ranges, we award the PowerBlock Adjustable Kettlebell a near-perfect score of 4.5 out of 5 in this key category.
Shape
While some prefer the round shape of a traditional kettlebell, our expert product tester rather enjoyed the relatively flat face of the PowerBlock Adjustable Kettlebell. In fact, this unique design can actually enhance your experience in some movements.
“This is relatively flat, making it more comfortable to rest on an arm or shoulder when performing certain exercises,” our expert product tester explains. “The spherical ones sometimes can create discomfort across a specific pressure point when against the body.”
We’ve seen some reviews mention that the square shape doesn’t feel quite as good as a round kettlebell on explosive movements, like the kettlebell snatch. However, some users love the shape of the PowerBlock, so this ultimately comes down to personal preference. Overall, we rate the shape at 4 out of 5.
Handle
A well-designed handle allows you to maintain your flow during a workout. On the other hand, a poorly crafted one can cause more headaches than the kettlebell is worth. According to our product tester, the PowerBlock’s handle is smooth without being slick. Although there’s no knurling as you’ll find on the best Olympic barbells, our tester said there were no issues with the kettlebell slipping out of his hand during training.
Our tester tried the grip both with and without lifting chalk and said the added compound didn’t seem to make much of a difference—a testament to how good the PowerBlock grip is. Our tester also noted that the handle is a bit thicker than traditional kettlebells, which he enjoyed. The handle diameter of 32.77 millimeters is about exactly what we see with the average adjustable kettlebell (33 millimeters).
As a 6-foot-4 lifter with larger hands, our tester felt very comfortable using the kettlebell, saying most people should have no problems with the grip size. As a result, we give the handle a perfect 5 out of 5 rating.
Price
If we’re being honest, the PowerBlock Adjustable Kettlebell’s price tag makes us hesitate to group it with the best budget home gym equipment. That said, you do get what you pay for in terms of build quality.
The smaller-sized model costs $199—not exactly a bargain but also not absurdly overpriced. Meanwhile, the larger ‘bell costs $349. For comparison, that’s about the same as a pair of 30-pound REP Fitness QuickDraw Adjustable Dumbbells—our top overall pick in that category.
Based on our research and testing, the average adjustable kettlebell costs $165, so PowerBlock priced these fairly. These aren’t a steal by any means, but we feel comfortable giving a moderate 3 out of 5 rating for price and overall value.
Customer Experience
This kettlebell comes with a five-year warranty when you purchase from PowerBlock, which is nice to see, although other companies like REP offer lifetime coverage bundles.
To reach customer service, you can use a contact form, email, or call PowerBlock’s customer service center. PowerBlock does accept returns within 30 days, but you’ll be charged a 20% restocking fee and have to pay for your own return shipping. As such, we docked a point off the customer experience score for a 4-out-of-5 rating.
Customer Reviews
The PowerBlock Adjustable Kettlebell has earned an average rating of 4.9 stars on the company website and 4.6 stars on Amazon. Overall, that speaks volumes to how highly regarded it is by customers who’ve made it a foundational piece of their home gym.
Most reviewers love using this kettlebell and feel that it’s very durable, especially when compared to other brands that may not have the same level of build quality. The only negative reviews I could find mentioned a slight rattling sound from the pin during use, or damage during shipping—though our kettlebell arrived in perfect condition.
PowerBlock Adjustable Kettlebell Vs
There are quite a few high-quality adjustable kettlebells on the market now, so let’s compare this one to the REP Fitness Adjustable Kettlebell—our top pick in this emerging category.
The primary difference is the shape—the REP Adjustable Kettlebell has a traditional round shape, while the PowerBlock features a square design that’s anything but traditional. This comes down to a matter of personal preference, as some users may find the PowerBlock a bit awkward.
Meanwhile, the REP model offers a maximum weight of 24 kilograms (53 pounds). That should be sufficient for beginners and intermediate lifters, but with a maximum weight of 28 kilograms (about 62 pounds), the PowerBlock kettlebell offers a bit more room to build muscle and strength via progressive overload1. It’s worth noting, however, that the REP kettlebell includes five different weight increments, while the PowerBlock kettlebell only includes four available working weights.
Overall, the PowerBlock kettlebell is best for those who prefer a heavier weight or a square design, while the REP kettlebell can be ideal for those who want to use an adjustable kettlebell with a traditional shape.
Another alternative worth considering is the Titan 10-40 LB Adjustable Kettlebell. This well-priced model replaces seven kettlebells in one profile and features an extra-wide handle for a secure grip. It isn’t an ideal option for seasoned lifters looking to go heavy, but we highly recommend it to beginners who want a traditional kettlebell shape over the PowerBlock’s cowbell-like design.
| PowerBlock Adjustable Kettlebell | REP Fitness Adjustable Kettlebell | Titan 10-40 LB Adjustable Kettlebell | |
| Price | $199 or $349, depending on the size | $149-$219.99, depending on the size | $149.99 |
| Weight Range | 18-35 lbs (8.18-15 kg), 35-62 lbs (16-28kg) | 8-16 kg, 16-24 kg, 20-40 lbs | 10-40 lbs |
| Change Increments | 4-9 lbs | 2 kg or 5 lbs | 4.6-6 lbs |
| Handle Diameter | 32.77 mm | 35 mm | 28 mm |
| Replaces | 4 kettlebells | 5 kettlebells | 7 kettlebells |
| Material | Alloy steel | Cast iron shell with matte powder coat | Cast iron |
| Adjustment Mechanism | Magnetic selector pin | Push-and-turn dial | Dial and plates |
Final Verdict of Our PowerBlock Adjustable Kettlebell Review
Overall, this is a durable kettlebell with a comfortable grip, easy-to-use pin adjustment, and space-saving design. Traditional kettlebell enthusiasts may find the square shape to be awkward, but our product tester still enjoyed his experience. PowerBlock deserves a tip of the cap for crafting a compact cardio and strength training tool that gives you ample flexibility to attack different muscle groups efficiently.
Ultimately, this in-depth kettlebell review should give you confidence about pulling the trigger on PowerBlock.
- With two different sizes available, PowerBlock makes it possible for both beginners and more seasoned lifters to work within an ideal weight range.
- You may need to choose a different brand if you prefer a traditional kettlebell shape.
- The steel exterior and powder-coated finish give a similar feel to standard cast-iron bells.
- The five-year warranty policy exceeds the industry standard, adding even more value to your purchase.
PowerBlock Adjustable Kettlebell Review: FAQs
What are the cons of adjustable kettlebells?
While all adjustable kettlebells are manufactured differently, some may rattle a bit when using them for movements like kettlebell swings, which can lead to a perceived feeling of instability. Some brands also warn against dropping them, so not all adjustable kettlebells are as durable as their standard, cast counterparts.
How do adjustable kettlebells work?
Adjustable kettlebells allow you to change between several weight increments without having to keep multiple kettlebells at your disposal. Most of them use some kind of twist or pin system to add and remove weight from the center of the kettlebell.
Do I need kettlebells if I have dumbbells?
While both kettlebells and dumbbells are versatile free weights that allow you to perform a variety of workouts, they feel different to use. With dumbbells, the weight is centered in your hand, whereas with kettlebells, the weight is usually a few inches away from the handle you’re holding, which changes the feel of the exercise. You don’t particularly need kettlebells if you have dumbbells, but they can be nice to have for added training variety!
Are adjustable kettlebells worth it?
Yes, for most people (especially home gym owners), adjustable kettlebells can be worth the cost. They save space and allow you to use a variety of weights without needing multiple kettlebells. However, some models aren’t as durable as others, so they may not work as well for commercial gyms or CrossFit boxes where they’ll be heavily used each and every day.
