Overview
The Rogue Thompson Fatbell is a revolutionary evolution of the traditional kettlebell, co-developed with powerlifting legend Donnie Thompson. By relocating the handle to the center of a hollow cast-iron sphere, the Fatbell creates a "perfect geometric shape" where the athlete's hand and the weight act as a single unit. This center-mass design improves balance, maximizes performance efficiency, and significantly reduces the shearing forces on joints commonly associated with traditional offset kettlebell handles.

Key Features and Specifications
Innovative Design: Internal handle positioned at the center of the mass for optimal load distribution.
Construction: Solid cast-iron sphere with an open-ended design.
Finish: Rogue's signature black powder coat for a superior, grip-friendly texture.
Handle Diameters:
9LB - 18LB: 32MM diameter Ergo Handle.
26LB - 88LB: 37MM diameter Ergo Handle.
97LB - 150LB: 40MM diameter Ergo Handle.
Weight Range: Available in increments from 9 lbs up to 150 lbs.
Visual Identifiers: Features a color-coded stripe around the opening for quick weight recognition in a gym setting.
Base Design: All bells 26 lbs and up feature a flat machined base for stability when set down.
Dual Openings: The 9LB, 13LB, and 18LB models feature a second opening on the bottom to accommodate athletes with smaller hands.
Performance Benefits
Joint Safety: Because every point on the surface of the sphere is equidistant from the center of the hand, the design reduces torque and shearing force on the wrists, elbows, and shoulders.
Balance and Efficiency: The center-mass loading ensures that the weight does not "flop" or rotate around the wrist during snatches and cleans, leading to a more stable and predictable movement pattern.
Muscle Activation: Increases load distribution on the target muscles and connective tissues rather than taxing the grip and joints with offset weight.
Versatile Hybrid: Combines the best attributes of a dumbbell and a kettlebell, making it suitable for presses, swings, lunges, snatches, cleans, and rows.
Maintenance and Care
Cleaning: Wipe down with a damp cloth and mild soap to remove chalk and sweat. Avoid using harsh chemical cleaners that could degrade the powder coat finish.
Knurl/Grip Care: Use a nylon brush to clear excess chalk from the internal ergo handle to maintain optimal friction.
Surface Inspection: Due to the casting process, minor variances in the finish may occur. Periodically inspect the bell for any deep chips in the powder coat and touch up with a metal-safe matte black paint if necessary to prevent oxidation.
Storage: Store on a flat surface or a specialized kettlebell/dumbbell rack. Avoid storing in high-moisture areas for extended periods to maintain the integrity of the cast iron.
Warranty Information
Standard Warranty: Rogue provides a proprietary warranty on cast-iron products, typically covering manufacturing defects for a period of one (1) year.
Exclusions: The warranty does not cover standard cosmetic wear, such as chipping of the powder coat from contact with other metal equipment. Damage caused by dropping the Fatbells on non-rubberized, hard surfaces (like concrete) is also excluded.
Frequently Asked Questions
Q: How do I choose the right size? A: Because the handle is internal, the bell's diameter increases with weight. Ensure the bell size is comfortable for your arm length during movements like presses. Generally, athletes transition to Fatbells using weights similar to their kettlebell or dumbbell working sets.
Q: Can I do standard kettlebell swings with these? A: Yes. The Fatbell is excellent for swings. The center-mass design provides a very stable "pendulum" feel that many users find superior to a standard kettlebell.
Q: Are these sold as pairs? A: No, Thompson Fatbells are sold individually. If you wish to use them for bilateral movements like bench presses or dual-arm rows, please adjust your order quantity to two (2).
Q: Will the sphere hit my forearm during presses? A: The sphere is designed to surround the hand. During a press, the weight is distributed around your arm rather than resting on the back of your wrist, which many lifters find much more comfortable than traditional kettlebells.
