Unique Fat Bar Adaptors to Target Your Pinch Grip?

(Last Updated on October 23, 2025 by Henry)

Overview:

From my experience, Grenadier Grips are a seriously impressive addition to any grip training setup. They look simple, yet the rounded, baseball-sized design completely changes how your hands and forearms work during training. Instead of relying only on your fingers and palms like with flat, thick bars, these spherical grips engage your thumbs, wrists, and forearm stabilizers much more effectively.

It’s one of the few tools that genuinely challenge your pinch grip and help you build that crushing, functional strength that athletes rely on. The ergonomics are on point, too. The rounded surface takes away wrist pain that straight handles often cause, allowing you to train longer without discomfort.

I’ve found these grips perfect for transforming almost any piece of gym equipment into a strongman-style fat bar, whether you’re curling, pulling, or pressing. The added challenge creates an incredible pump and instantly makes your workouts more productive.

They’re built tough, yet soft enough to feel comfortable. The anti-slip, high-grade elastomer feels secure even when your hands are sweaty, and the material quality ensures they’ll last years of use. It’s a small, versatile piece of equipment that goes a long way.

If your goal is to build forearm size, enhance grip endurance, and protect your joints, Grenadier Grips are a must-have.

Whether you’re into arm wrestling, climbing, bodybuilding, or martial arts, they deliver exactly what serious grip training should: more muscle activation, better hand control, and a huge step up in overall grip strength.

Unique Gripping Position

Thumbs & forearms, in general, are typically the weakest links in anyone’s body. Thick bar handles are made to train these weak links & quickly become notable in your workout routine. Walking up to a loaded bar with a weak grip makes you feel like you are handicapped. The benefits are tremendous in building a stronger grip.

In addition, thick bar handles target your whole upper body in general. More muscle activation naturally leads to bigger muscles & functional strength gain. Thick bar adaptors have become a worldwide training phenomenon. Top-level athletes swear by it, recommending it to others while using it themselves. Ideal for military, martial artists, arm wrestlers, crossfitters, and bodybuilders.

Using Grenadier grips can also reduce joint-related problems. The older you get, the more joint pain you encounter. By not gripping metal directly, fat grip bar handles help to take the pressure & stress off the joint. Put it where it counts, on the muscle, and avoid the pain. Increasing the surface area of targeted muscle protects joints, resulting in a stronger body & fewer joint problems.

Versatility is Off The Charts

1 Olympic Bars: Ideal to focus on repetitions: Curls, shrugs, deadlifts, as well as all types of bench presses – Flat, incline & decline, military press, close grip & J.M. presses

2 Dumbbells: Use thick bar handles for most dumbbell exercises. Please be aware that not all dumbbells have handle shapes that could accommodate Grenadier Grips

3 Odd bars: Even thinner bars than your standard Olympic ones work well with thick bar handles. Grips may rotate on an inert bar; however, the resistance of the weight will keep grips in place during exercise

4 Cable machines: Most cable attachments are ideal to fit your Grenadier Grips. You can use them for a variety of exercises, ranging from pull-downs, rows & curls to all sorts of extensions

5 Free-standing machines: Most commercial gym trainer machines are excellent targets to apply your thick bar handles

6 Pull-up bars: Easy to apply within seconds. Most of the pull-up bars are suitable & you can start your exercise quickly

Won’t Fit Every Dumbbell

Dumbbells come in various shapes & sizes, which apply to their handles as well. If you have a fancy dumbbell with a special coating put over its handle or just a regular metal one with an odd-shaped handle, you run into problems.

Grenadier Grips, like other thick bar handles, come in one diameter only. They easily fit your standard barbells & handles, but anything too fancy & out of the ordinary is where the fat grip handles will hit the wall.

In most cases, handles still fit but barely. You have to test it; it can still be functional, but maybe it’s a deal breaker for you. The last resort option would be to cut into your thick bar adaptors to fit them specifically for your device. But it will be hard to do because the material used in these handles is tough to just casually slice through.

Saves You Chalk

With Grenadier Grips, you hit multiple targets at once: grip strength, forearm development, and better training ergonomics. This is one of the best pieces of gear to own, no matter your sport or discipline. The sheer versatility of these thick bar handles is off the charts. You can use them on barbells, dumbbells, pull-up bars, or cables to enhance nearly every exercise and see faster, more balanced results.

The rubber-like compound eliminates the need for chalk while providing a superior non-slip grip. That extra traction gives you greater control over dynamic push and pull movements, helping you train more efficiently and safely while reducing fatigue and joint stress.

The rounded, baseball-style shape delivers a completely new feel and lets your hands stay in a natural, pain-free position during curls and presses. It relieves pressure from the wrists and elbows, allowing you to perform movements that once felt awkward or even impossible. Portability is another win; it takes seconds to attach or remove them, and their compact size means you can throw them in your gym bag and train anywhere.

Built from a high-grade elastomer polymer, these grips are practically indestructible and built to last a lifetime. In short, Grenadier Grips are an elite, portable way to supercharge your pinch grip, forearm endurance, and hand strength, all while protecting your joints and elevating your overall training experience.
