Fat Gripz (Axle Bar Adapter)

$40.00 CAD

Fat Gripz (Axle Bar Adapter)

Made from a military-grade, high-density compound, Fat Gripz can instantly transform any standard barbell into an axle bar (thick bar). They also fit most dumbbells, pull-up bars, and cable attachments, – doubling the thickness for a greater test of arm and grip strength. Once attached, Fat Gripz hold to the bar firmly like a clamp, and won't compress – even you're deadlifting extreme loads.

Thick bar training has become increasingly popular with athletes and military personnel around the world, and lightweight, portable Fat Gripz enable them to get the benefits of an axle bar wherever they are. From U.S. Special Forces to NFL teams, top MMA fighters, the Grace Barra, and your own local box, you can find dedicated users of the product.


  • Sold as a Pair

Rated 5 out of 5 by from Great product. I was having problems with my wrists. I am a UPS driver and spend most days using my hands. After using the Fat Gripz on my arm and back days pain is gone. Not to mention my grip strength has increased significantly. Partly due to the fact that I can now squeeze the bar pain free. I don't write reviews often but this is a life changer for someone who works with their hands.

Rated 5 out of 5 by from That Stupid PUMP! Never had a stupid pump on my fore arms. A stupid pump is when you get so much blood flow to specific muslces they swell and hurt do use them. I'm happy I got these, I wish I got them on black friday though. I use for DB farmers walk, cursl and tricep kick backs. Pump is like no other. Prepare to feel the burn!

Rated 5 out of 5 by from This is a must in anyones arsenal I bought these thinking it would be a change to the work out. I found that I had to drop about 50% of the weight on my up right rows and other similar movements. Because my grip did not have the strength to hold on to a fat bar. I have been training with them now for about three years and love them. If you ever come up against an axle bar you will not get it off the gowned unless you know how to squeeze. Fat gripz teach you how to squeeze !

Rated 5 out of 5 by from Awesome Product Great tool for training. Helps creat a pump on any upper body movement. Exposes any forearm weakness

Rated 5 out of 5 by from Great accessory. Besides the intended use, I use them on multi-grip bar and also when I do Zercher squats. They keep the bar from tearing up your arms and allows you to focus on the movement and not the discomfort of the bar.

Rated 5 out of 5 by from Excellent Product I purchased these to use with my dumbbells, pull-up bar, and deadlift bar. The Fat Gripz has worked with all of them, and switching back and forth is not an issue.
