The REP Adjustable Kettlebell is a fast, space-friendly option that replaces five traditional kettlebells. Available in three options, it carries a max weight of 24 kg (~53 lbs) and uses a simple weight dial system. It looks and feels like a conventional kettlebell, offers a mostly cast iron construction, and comes with a lifetime warranty.
Who It’s Right For
Things to Consider
To put it simply, the REP Adjustable Kettlebell is one of the best adjustable kettlebells on the market.
It blends speed with performance and truly looks and feels like a traditional kettlebell.
Its space-saving design replaces five fixed kettlebells, and I appreciate that REP offers several weight ranges for different experience levels.
However, there are some considerations with this design that may not make it a fit for everyone.
In this review, I’ll cover everything you need to know about the REP Adjustable Kettlebell. I’ll share the pros and cons and compare it to other popular options, including Bowflex and Ironmaster.
Let’s dig in.
REP Adjustable Kettlebell
When it comes to building a home gym, it’s important to maximize versatility in the space you have. Kettlebells are definitely versatile, but they can take up space if you have a lot of them.
An adjustable kettlebell solves that by putting multiple kettlebells into one, saving you a lot of space… and money.
Like adjustable dumbbells, kettlebells can vary in materials, weight, adjustment type, and more.
One of the things I like most about the REP Adjustable Kettlebell is that they offer three weight options based on your strength level and goals. Combined with its cast iron construction, conventional shape, and easy-to-use weight system, it’s an excellent option for most people.
Let’s take a look at the specs and then jump into the review.
|REP (16-24 kg)||REP (8-16 kg)||REP (20-40 lb)
|Max Weight||24 kg||16 kg||40 lbs|
|Weight Increments||2 kg||2 kg||5 lbs|
|Adjustment Type||Weight Dial||Weight Dial||Weight Dial|
|Weight Material||Steel & Plastic||Steel & Plastic||Steel & Plastic|

Design & Dimensions
It’s clear that REP designed its adjustable kettlebell to closely mimic the look and performance of a traditional fixed kettlebell. It offers a similar shape and size at 7.9″ W x 10.5″ H.
Some adjustable kettlebells have unique shapes or wider/narrower handles than standard kettlebells. These differences can alter range of motion, comfort, and overall effectiveness.
I’ve found the REP Adjustable Kettlebell comes the closest to matching the conventional feel better than any other non-competition option. I’m confident performing any kettlebell movement with it and have tried dozens of them, including squat variations, lunge variations, press variations, carries, snatches, rows, deadlifts, and more.
And thanks to its compact size, it’s now my travel companion on our annual beach trip.
The REP Adjustable Kettlebell is mostly built with cast iron, making it one of the most durable adjustables you can buy. Relative to some other options, I’m impressed with the amount of steel. The bell itself is thickly molded, and I have little concern over its long-term performance.
However, the weight dial system is made of plastic. The exposed top is mostly inconsequential since it’s a low-impact area, but the inner column could be an eventual source of weakness. While I would prefer more steel for additional peace of mind, an important mitigant is having tight tolerances.
And this kettlebell does. It’s not uncommon for some adjustable kettlebells to have some plate “play” or “slop.” When plates have room to move around, it creates stress on the system, which can eventually lead to problems with plastic components. I found very minimal play in these plates, meaning you get increased durability, improved balance, and reduced noise.
Lastly, REP included a rubber base to help protect your floor. It serves its purpose well but can sometimes fall off if you come down at an angle or drag the kettlebell on the ground.
A key benefit of the REP Adjustable kettlebell is how easy it is to operate. The weight dial is much faster than manual systems and can shave minutes off your training sessions. To change the weight, you push down on the dial (security feature) and turn it to the appropriate weight. There are numbered call-outs on the top for easy weight identification.
When you turn the dial, a column inside the bell adds or removes a series of selectors that lock in the necessary plates. Whatever you don’t use is left on the floor as you pull the kettlebell away.
If you’re completing a hard set, I recommend placing the kettlebell down before trying to place it back on the plate stack. Otherwise, you can knock it over, which can be annoying. Thankfully, REP includes arrows on each plate to let you know the proper orientation.
Overall, I’m a fan of this system. I have noticed on a few occasions that I need to press down on the dial a couple of times to unlock it, but if nothing else, it makes me more confident in the kettlebell’s security. And regardless, it’s still one of the fastest adjustables on the market.
One of my favorite features of this kettlebell is the handle. At 35mm, it has the same diameter as a competition kettlebell. Coupled with the textured powder coat, it feels excellent in the hands and provides a solid grip for swings, carries, etc. While most people will like the diameter, those will smaller hands may prefer something thinner like the Titan Adjustable Kettlebell or Bowflex SelecTech 840.
I also like the size of this handle. At 7.9″ wide, you can comfortably hold it for goblet squats and perform kettlebell swings with a traditional stance. The internal window of 5.8″ W x 2.8″ H provides plenty of room for your hands and helps contribute to the overall balance.
The REP Adjustable Kettlebell comes in three weight options: 8-16 kg, 16-24 kg, and 20-40 lbs. I recommend the 16-24 kg to most people since it covers some of the key kettlebell increments. You can perform heavier swings, squats, carries, etc., and the 24kg max weight is near the top of the market.
The 8-16 kg option is better for beginners or casual lifters, while the 20-40 lb version is good for those who prefer pounds and/or need a weight option that falls in between the other two.
Each kettlebell offers five weight increments in either 2 kg or 5 lb jumps. I like the smaller and more consistent increments compared to some other adjustable kettlebells and find that it helps progressively overload.
The REP Adjustable Kettlebell comes with a limited lifetime warranty, putting it at the top of its class. They’ll cover any defects in materials, functionality, and workmanship for life. Coverage ends if the kettlebell becomes unusable for reasons other than those. I recommend avoiding dropping the kettlebells. It also won’t transfer to a second owner if you’re planning to buy this used.
The adjustable kettlebell from REP gets very good reviews overall. Most people love how easy it is to adjust and the grippy handle. They also appreciate the traditional shape, balance, and cast iron construction. Most criticisms point to the plastic found on the dial and selector column. Although no reviewers experienced failures, they question the long-term durability.
REP Adjustable Kettlebell vs. Bells of Steel Competition Adjustable Kettlebell
The Bells of Steel Competition Kettlebell is a great comparison to REP because it offers a similar look and traditional design. However, their loading mechanics are quite different in addition to a few other things.
The biggest difference between these two is that the Bells of Steel Kettlebell is plate-loaded and takes considerably longer to load. I’m talking 1-2 minutes vs. a few seconds on the REP. Unlike other plate-loaded designs, this one has a split body with bolts and threaded nuts that must be adjusted along with the weight.
While it takes longer, this design is extremely durable and doesn’t include any plastic. You can also load it heavier, up to 32 kg (~70.5 lbs). Bells of Steel provides all the necessary plates, with increments ranging from 0.5-3 kg. All-in, it offers 41 total weight increments, making it extremely versatile.
Both handles have a 35mm diameter, but as a competition bell, the Bells of Steel handle is straight with a steel finish (vs. rounded with powder coat). If you perform a lot of single-arm movements, you may prefer the straighter handle. I gravitate more toward the REP handle, but they both feel great.
Both offer a lifetime warranty and free shipping, but the Bells of Steel Adjustable Kettlebell is more expensive. The 20.5 kg BoS option is consistent with the 24 kg REP Kettlebell, but the 32 kg option is around $100 more.
If you’re a competitive kettlebell athlete or someone who demands the best, I recommend the Bells of Steel Competition Adjustbell Kettlebell. Otherwise, the REP Kettlebell is faster, easier to use, and more affordable.
REP Adjustable Kettlebell vs. Bowflex SelecTech 840
The Bowflex SelecTech 840 is one of the most popular adjustable kettlebells on the market and is a good comparison to REP because of the weight dial system.
Both of these kettlebells are lightning-fast and easy to operate. Unlike the press-and-turn system on the REP, the Bowflex uses a special docking station that unlocks the dial. When docked, you simply twist it, making it arguably easier to use. However, because the REP doesn’t require the dock, it’s slightly more versatile and efficient.
In terms of weight, the Bowflex 840 ranges from 8-40 lbs in varying increments between 4-10 lbs. It replaces six kettlebells vs. five on the REP and is most similar to the 8-16 kg REP option. While I like the extra weight option on the Bowflex, I prefer the tighter increments on the REP Adjustable. Heavier lifters and more advanced kettlebell users will also likely gravitate toward the heavier 16-24 kg REP option.
The REP kettlebell looks and feels more like a traditional kettlebell than the Bowflex. The 35mm handle is thicker and has a textured powder coat, while the Bowflex is narrower, thinner (28mm), and more slick. The REP’s cast iron body is also more durable than the Bowflex’s plastic shell, which is likely why they offer a lifetime warranty compared to only two years with the Bowflex.
Price-wise, the SelecTech 840 is comparable to the 8-16 kg REP kettlebell. Both offer free shipping, but you can expect to pay around $50 more for the heavier REP kettlebell.
In my experience, REP makes a better adjustable kettlebell. The Bowflex is a nice budget/beginner option, but the REP’s design is superior and offers better value.
Pros and Cons
The REP Adjustable Kettlebell is a great option for those wanting to save space and money. I love how quickly I can adjust the weight and how it feels like a traditional kettlebell.
Although the weight dial is plastic, the cast iron construction is more durable than most. I also appreciate the thicker handle and grippy texture.
While the price is higher than some adjustable kettlebells, the quality and warranty are worth it if you have the extra cash. Overall, this is one of the best adjustable kettlebells on the market.
