Thompson Fatbells

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.

I love the fatbells, I think these will be very collectible one day. They are high priced, but top level quality, I am getting almost all mine used. This is one thing I constantly search for on marketplace.

Fat bells are awesome! But there are some trade offs with them and the Center Mass Bells. These are labeled like kettlebells, which I prefer, and have better handles. However, the center mass bells are more durable and can be picked up from either side or used to do rotational work and throws. I highly recommend these as they do sit in a unique way that often is my work around if dumbbells are an issue. Similar to kettlebells, I would start with the pairs you use there (for more than just swings).

These are too pricey for me to get a set but really enjoy the feel of the pair I have (13lbs)

I used these at my local gym and they ruined regular dumbbells for me. I honestly think these are the best possible dumbbells out there and find myself using my adjustables less and less. The leverage you have on these feels excellent and the balance itself is perfect.

These feel amazing but I could never justify the cost, not to mention most people would still use dumbbells anyway

I didn’t think I would like these as much as I do. If money and space was no issue, I would likely have these over regular dumbbells. I do not think they replace kettlebells. I also prefer these over CMBs, because of the handle shape.

Really like using the Fatbells. They do a nice job of filling in some of the gaps in my dumbbell weights too. Wouldn't be the first thing if I was starting a home gym but once you have the essentials, cool to add.

I really like these and want to use them more than I do, but I haven’t yet gotten additional pairs, which is stopping me from doing more with them. I was spoiled and got these used for a song, and now I can’t justify spending Rogue money on some more. I do prefer them to kettlebells. It’s not a 1:1, but close enough for my needs.

These are cool, however they're a bougie, low use item in my opinion. I'd rather have a dumbbell or kettlebell in most cases and when you consider having to buy a pair of these to do some movements it gets pricey and eat up a lot of floor space.

My hands and wrists are huge so I struggle with a lot of these. But when a buddy calls and says “Rogue has 150 lb fatbells in the garage sale at $1 a lb - you want em” - you just roll the dice and pray. They do hit me a little weird but for price I don’t care. They are big. They are heavy. I press them - and I get stronger.
