Overview
Fat Gripz are a versatile, military-grade training accessory designed to instantly convert standard barbells, dumbbells, pull-up bars, and cable attachments into "thick bars" (axle bars). By increasing the diameter of the handle, Fat Gripz force greater muscle activation in the hands, forearms, and upper arms. This "plug-and-play" tool is used by world-class athletes, NFL teams, and Special Forces to unlock new levels of strength and muscle mass without requiring expensive specialized machinery.

Key Features and Specifications
Material: Made from a military-grade, high-density compound that grips the bar like a clamp.
Non-Compressive: Unlike cheap foam imitations, these will not compress or slip, even under extreme deadlifting loads.
Beveled Ends: Designed with beveled edges to ensure a flush fit even on angled equipment like E-Z curl bars.
Sold as a Pair: Each order includes two grips.
Available Models:
Fat Gripz One (1.75” Diameter): Ideal for those with smaller hands or as an entry point for thick-bar training.
Fat Gripz Pro (2.25” Diameter): The industry standard; best for most athletes and general strength goals.
Fat Gripz Extreme (2.75” Diameter): The ultimate challenge; intended for advanced grip specialists and strongmen.
Portability: Lightweight and compact enough to fit in any gym bag, making them ideal for travel or commercial gym use.
Performance Benefits
Increased Muscle Activation: Thicker handles stimulate more motor units in the hands and forearms, leading to rapid gains in grip strength and arm size.
Joint Health: By spreading the weight over a larger surface area of the hand, Fat Gripz can help shift stress off the joints (wrists and elbows) and onto the muscles.
Eliminate Weak Links: Thick bar training targets the hands and forearms—often the first points of failure in heavy pulls—allowing the rest of the body to reach its full potential.
Natural Movement: Replicates the natural function of the human hand when lifting heavy, awkward, or non-uniform objects found in real-world scenarios.
Maintenance and Care
Cleaning: Use a damp cloth with mild soap and water to remove sweat, chalk, and dirt. Because the material is high-density, it is resistant to absorbing moisture.
Sanitization: For gym-wide use, standard non-bleach sanitizing wipes are safe and effective for maintaining hygiene between users.
Longevity: Avoid leaving the grips in direct sunlight for extended periods to prevent the compound from becoming brittle over time.
Storage: Store them in a dry place. The material is "built to last a lifetime" and does not require special oils or treatments to maintain its grip.

Fat Gripz are built to be virtually indestructible and are intended never to need replacing. Rogue Fitness observes a 30-day return policy for items in new, unused condition. For specific manufacturing defects beyond the initial purchase period, users can refer to the manufacturer's long-standing reputation for durable, high-density performance gear.
Frequently Asked Questions
Q: Which size should I start with?
A: If you are unsure, start with the Fat Gripz Pro (2.25"). It is the most popular size and provides a significant challenge for most lifters. Move to the Extreme (2.75") only once you have mastered the Pro.
Q: Will they fit on my pull-up bar?
A: Yes, Fat Gripz are designed to fit virtually all standard barbells and pull-up bars (approx. 1" to 1.15" diameter).
Q: Do I need to use less weight with Fat Gripz?
A: Yes. Because your grip will be the limiting factor, you will likely need to reduce the weight by 10%–25% initially as your hands and forearms adapt to the increased diameter.
Q: Can I use them for deadlifts?
A: Absolutely. They are one of the best tools for building "support grip" during deadlifts, though they will make the lift significantly harder.
