Rogue Thompson Fatbells Review (2022): A Great Lifting Alternative

The Rogue Thompson Fatbells are a collaboration between Rogue Fitness and powerlifting legend Donnie Thompson that are designed to essentially replace both kettlebells and dumbbells. We find, after using them for more than two years, that they are a great addition to training, but not a perfect replacement for kettlebells. They could be a great alternative to the standard dumbbell and I use a similar style of handheld weight for much of my dumbbell training.

In this Rogue Thompson Fatbells review, we’ll go over what it’s like to lift with these hybrid free weights and whether we’d recommend them for most people’s home gyms. 

Why You Should Trust Us

For one, my neighbors know me as “that guy who always has boxes delivered to his front step.” I’m kidding, but only a little. In all seriousness, I’m always trying to get my hands on the latest and greatest home gym equipment so I can give you an unbiased and thorough review so you can click “add to cart” on the best barbells, squat racks, and free weights for your home gym. 

Just as I do in this Fatbell review, I go over everything from how a free weight feels when you first put your hand on it to how durable the material it’s made of is likely to be. I also do my best to update these reviews to let you know how certain equipment has stood the test of time (some do a lot better than others). 

A Quick Look at the Rogue Thompson Fatbells

Every once in a while a fitness device comes around that changes the industry. The traditional dumbbell, one of the most prominent pieces of exercise equipment in gyms around the world, has stayed relatively the same for some time (with the exception of adjustable dumbbells).

It has a handle with two weights on either side of the hand and is mostly used for pressing and pulling movements. Sometimes for snatches as well.

The kettlebell, a piece of training equipment that has also been around for quite a while, possibly longer, has made its way into the hearts and minds of the general training public in the USA pretty heavily within the past two decades. The kettlebell, for those unaware, is mostly used for dynamic movements like swings, snatches, and clean and jerks.

Just imagine with me for a second though what it would look like to combine the two.

That’s exactly what Rogue has done in partnering with Mr. 3000 himself, Donnie Thompson, in creating the Rogue Thompson Fatbells.

Coop’s Tips:

• This is great for people looking for a dumbbell alternative, but not those seeking a kettlebell alternative. 
• Try one or two Fatbells before purchasing an entire set 

Are the Rogue Thompson Fatbells Worth It?

What you really wanted to know, and what I wanted to know was simply: “Why should I purchase Fatbells versus dumbbells or kettlebells?” First off, I’d like to say, all three have their place.

But, I want to be clear when I say, if I could only choose one, I would choose the Rogue Thompson Fatbells (I just wish they would have made the weight increments match dumbbells, not kettlebells…)

The five main reasons why I’d pick them over the more classic free weights are more versatility, improved muscle contraction, a more cohesive hand-weight connection, the weights’ smaller diameter, and the fact that they could provide a bit more safety. 

This is my opinion, though, and I would pick Fatbells because they feel good to me and work well for my personal training goals. But you may not feel the same, and that’s OK. Here’s who I think might side with me, and who should probably just stick to dumbbells or kettlebells. 

(If you choose the latter, check out my dumbbells vs. kettlebells comparison to check out which one of those two are the best for you).

Benefits of Using the Rogue Thompson Fatbells

The Fatbells are solid, simple as that. They aren’t overly complicated, and the 53-pound Fatbell I purchased is just over 53 pounds, which is pretty good considering they’re made of cast iron.

Let’s now break down exactly why one should use a Rogue Thompson Fatbell over a dumbbell or kettlebell. 

Versatility 

You can do everything you can do with a dumbbell with the Fatbells. In my opinion, they’re a dumbbell replacement that will lead to fewer wrist injuries as well as a better connection. You can also use them for one-arm swings, snatches, clean and jerks, and just about everything you can do with kettlebells except for two-handed swings. Two-handed swings are considered by many in the kettlebell world to be an improper use of the kettlebell anyway.

Blood Gorging

This is a little hard to explain, but in speaking with Donnie Thompson, he spoke a lot on how the muscles became much more engorged with blood (or, in other words, more blood rushes to them) than when you use the traditional dumbbell or kettlebell. This is something I also noticed, but mainly at higher repetitions.

Essentially, this happens because the Fatbell is causing more muscles to kick into high gear than if you were holding a kettlebell or dumbbell. This phenomenon, known as muscle recruitment, causes blood to flow to the muscles needed to lift the weight so they have enough oxygen to help you eek out as many reps as possible, which in turn means you’ll build more muscle and strength. 

Hand-Weight Connection

When you place your hand inside of the sphere, it feels much more a part of your hand than any dumbbell, and especially a kettlebell. As is written on the description on Rogue’s website: “Every single infinitesimal point on the surface of that sphere is equal distance to the center of your hand.”

This causes fewer shearing forces on your joints and causes more load distribution on the muscles and connective tissue. You really have to use one to feel it.

Smaller Diameter

Due to the Fatbells’ diameter, you can get a much better contraction when pressing, such as on the bench press, due to being able to lower the Fatbells into a deeper stretch. With dumbbells, they’re so big and awkward they just get in the way causing many egos to grow (you know what I mean if you’ve ever been to a Globo gym and seen the guy benching with 150-pound dumbbells).

Safer

Due to the flat machined base, the Fatbells don’t roll around. They also don’t rock back and forth in your hand due to the weight being placed 360 degrees around it. They’re also easy to dump and I never felt any worry about getting cut by the edge of the bell as it’s rounded and smooth.

Weight Increments 

My main beef with the Rogue Thompson Fatbells is in their weight increments. Currently, the Fatbells range from 9 to 150 pounds but they mimic kettlebell weight increments (which are based on an extinct unit of measurement called a “pood”). 

In my mind, kettlebells will always have their place due to the way the weight is loaded below the handle. The Fatbells are a dumbbell replacement. Meaning they should come in increments of 5 pounds, which I believe will happen when more people begin to adopt using the Fatbells.

Imagine walking into a gym and instead of dumbbells, you see a row of Fatbells. Eventually that will happen and it will be glorious!

Construction and Aesthetics

The Rogue Thompson Fatbells are made out of solid cast iron. There’s really no getting around how solid cast iron is, and it’s the same material many kettlebells are made of.

There is a 37-millimeter handle welded in the center of the 53-pound bell (it has a larger diameter for heavier weights, and a smaller diameter for lighter ones) that feels very similar to the size of some dumbbells. Because it’s cast iron, it also takes chalk really well, which allows you to get a great grip.

They look very similar to planter pots, and one reason for that is the bulbous shape and the flat machined base. As Rogue seems to do with just about every other piece of equipment they produce, it has a black powder coat finish.

To help identify the size of the bell, there is a stripe running on the inside lip of the bell. It’s a nice touch, and will help in commercial gym settings.

That being said, I don’t think the stripe was very well done. To me, it looks like somebody took a paint brush and just slapped it on. I would have liked to see a perfectly symmetrical line as I don’t think it would have been that difficult, but this is kind of just me nitpicking.

The History Behind the Rogue Thompson Fatbells

I’ve been following Donnie Thompson’s journey for quite some time.

Powerlifting was my first foray into strength training, as my father was a powerlifter many years ago and impressed upon me the importance of strength. When Donnie was attempting to break the 3,000-pound barrier (3,000 total pounds in the squat, deadlift, and bench), I remember seeing him on the cover of Powerlifting USA (a great magazine that is no longer around).

Donnie seemed to use unique training methods in building massive slabs of muscle, and one such method was using traditional kettlebells. This may seem like no big deal today, but a powerlifter using kettlebells 10 years ago was unheard of.

The story of the Fatbells’ creation is quoted on his personal website, and goes like this:

It was 2006 and I was training extremely hard for professional powerlifting. One night after squats, I went to bed and started dreaming I was swinging the 48k KettleBell. Suddenly, I pushed my hand into the center of the KB while holding the handle. My hand was dead center inside the KettleBell. It felt amazing. Control and ease of movement no matter what I did with it. IT WAS PERFECT. I woke up and immediately drew a picture of it. The time was 3am and I thought I was going crazy. Maybe too many KettleBell Swings? Not sure but continued drawing my dream and this is what I came up with:

The idea for what would eventually become the Rogue Thompson Fatbells was born.

If you’d like to read more of the story, which I find pretty interesting, you can find it here.

Long story short though, after talking with many companies, Rogue eventually decided to produce them, and Sorinex took his idea to create the center mass bells (sometimes called CMBs).

The Sorinex Center Mass Bells have two openings and are made from a stronger iron, but Rogue’s is a better value due to the lower price point. 

Ordering the Rogue Thompson Fatbells

Unlike dumbbells or kettlebells, you only get one Fatbell per order. Most weight increments are readily available, but you might have some difficulty if you’re looking to buy some of the lighter Fatbells. You can always ask Rogue to notify you when the weight increment you’re looking for is back in stock. 

Customer Experience 

Rogue Fitness is a very popular company, so while you can reach them through email, phone, or live chat it might take them a while to get back to you. That said, their customer service team is unmatched. 

While their Fatbells are more budget-friendly than similar products out there, that’s not the case for all Rogue products. Luckily, I’ve written a guide on how to save money on Rogue equipment.

Warranty and Returns 

The Rogue Thompson Fatbells come with a limited lifetime warranty, which just means Rogue will only replace them if there’s a manufacturing defect. You won’t get a replacement if you mistreat the Fatbell. 

You have 30 days from the date of delivery to return the product, in new condition and in its original packing. 

Customer Reviews

The Rogue Thompson Fatbells have a 4.9 average rating (out of 5) with 142 reviews on RogueFitness.com. A lot of reviewers expressed initial skepticism about the product, but were sold once they got their hands on it. 

“The Fatbell is a multi-exercise chunk of iron that is only limited by your imagination,” reviewer TSully Fitness from Washington State wrote. “It combines many of the features and exercises of both dumbbells and kettle bells. I plan on adding more to my modest home gym collection. I recommend one or two for you.”

Some of the negative complaints deal with paint chipping from the Fatbell. 

Final Verdict of Our Rogue Thompson Fatbells Review

The Rogue Thompson Fatbells are not a fad product.

I’m sure when dumbbells came out, many people looked at them as a silly idea. That’s typical of innovation and is very typical of innovation in the fitness industry. Mainly due to the Shake Weights and ab growers of the world.

I’ve been using Sorinex CMBs, which are essentially a more expensive Thompson Fatbell that feature holes on both sides and use ductile iron and I love the design. In fact, this design of handheld weight has replaced dumbbells for much of my training.

Rogue Thompson Fatbells are the best value for this style of hand weight and I certainly recommend them. Although, I want to be clear, I don’t think they’re a perfect substitute for kettlebells.
