Product Description

The Rogue Thompson Fatbell was co-developed with powerlifting legend Donnie Thompson as a revolutionary new take on the traditional kettlebell. With this design, we’ve made the simple but significant change of re-positioning the handle inside of the bell—set dead center and straight across like a dumbbell handle within an open-ended, cast-iron sphere. The result, as Donnie explains it himself, is a “perfect geometric shape for maximizing optimal performance,” as your hand and the bell essentially act as one. The center mass design allows athletes to improve the efficiency and balance of every swing/press while also reducing common kettlebell safety risks.

Rogue Thompson Fatbells

The Rogue Thompson Fatbell was co-developed with powerlifting legend Donnie Thompson as a revolutionary new take on the traditional kettlebell. With this design, we’ve made the simple but significant change of re-positioning the handle inside of the bell—set dead center and straight across like a dumbbell handle within an open-ended, cast-iron sphere. The result, as Donnie explains it himself, is a “perfect geometric shape for maximizing optimal performance,” as your hand and the bell essentially act as one. The center mass design allows athletes to improve the efficiency and balance of every swing/press while also reducing common kettlebell safety risks.

With your hand inside the sphere, “every single infinitesimal point on the surface of that sphere is equal distance to the center of your hand.” This dynamic reduces the shearing force on joints and adds more load distribution on muscle and connective tissue.

Rogue Thompson Fatbells are available in many different weight increments and include Rogue’s signature black powder coat finish. The 9LB, 13LB, and 18LB Fatbell feature an additional, second opening on the underside of the sphere for athletes with smaller hands.

Note: *Due to the casting process, cast products may have minor variances in the finish.

Original drawings from 2006 by Donnie Thompson.

A Donnie Thompson Innovation

For Donnie Thompson, decades of experience as both a champion powerlifter and world renowned trainer went into conceptualizing this new breed of kettlebell. Since his first sketch of a spheroid bell with an internal handle back in 2006, the blueprint was refined and perfected into its current dynamic form. If it meets Donnie’s standards, it’s up to just about anybody’s.

A “Perfect Geometric Shape”

The center mass design of the Fatbell allows athletes to improve the efficiency and balance of every swing/press while also reducing common kettlebell safety risks. As Donnie Thompson puts it, this is the “perfect geometric shape for maximizing optimal performance,” as your hand and the bell essentially act as one. “Every single infinitesimal point on the surface of that sphere is equal distance to the center of your hand.” This dynamic reduces the shearing force on joints and adds more load distribution on muscle and connective tissue.

Quality Construction

Thompson Fatbells feature a solid, cast-iron construction with a black powdercoat finish and a grip-friendly ergo handle. The exterior design includes both Rogue and Thompson branding, as well as a color-coded stripe around the opening for quick recognition. All bells 26LB and up have a flat machined base, while the 9LB, 13LB, and 18LB bells are opened-ended on both the top and bottom, providing an alternative option for athletes with smaller hands.

Wide Range of Sizes

Whether you want to order a couple sets of Fatbells for your home gym or equip a larger facility with a full arsenal, there is no shortage of options [see the size chart below or within the order menu]. Bear in mind that along with the diameter of the bell itself, the diameter of the internal Ergo Handle also changes depending on the weight of the Fatbell:
9LB - 18LB Bells = 32MM diameter handle
26LB - 88LB Bells = 37MM diameter handle
97+LB Bells = 40MM diameter handle

Variety of Applications

As a hybrid of sorts between a traditional kettlebell and dumbbell, there are countless ways to utilize Thompson Fatbells and incorporate them into your routine; from presses, swings, and lunges to snatches, cleans, rows, and more.

Thompson Fatbells
I love the Thompson Fatbells. I think they are far better than traditional dumbells. The downside is they take up more physical space. They are worth the purchase

A must have!
Thompson Fatbells are a different kind of animal! I have been a competitive bench press specialist and have held multiple all time world records in the 220, 242, and 275 lbs weight classes. There is no better assistance tool to build a world record breaking bench press than the Thompson Fatbellls. I bought the complete set 10 years ago when they came out. And when more weights were added I added them to my complete set! These should be in any serious home gym or commercial gym.

The Most Useful Tool in my Garage Gym!
The Fatbell is hands down the most useful tool in my garage gym. I remember when they first came out — my son actually won a 9-lb Fatbell at a seminar, and after trying it out I was immediately sold. Within days, I ordered a full set ranging from 13 to 70 lbs. What makes the Fatbell so innovative is its design. It combines the feel and control of a dumbbell with the center-mass balance of a kettlebell, giving you the best of both worlds. The unique “hollow” handle design allows your hand to sit inside the bell’s mass, improving leverage, stability, and joint alignment through every movement — from presses and snatches to carries and curls. In a garage gym where space and versatility matter, the Fatbell stands out as a compact, durable, and highly functional tool. It’s built for serious training — adaptable to nearly every strength and conditioning exercise — and perfect for anyone who values efficiency and results over gimmicks. If I had to pick just one piece of equipment to keep, the Fatbell would be it.
