Tips from the Pros


"The research has shown that using thick-grip implements [Fat Grips] recruits more motor units [muscle fibers] especially in the elbow flexors [biceps and brachialis]. That means training with thicker diameter handles will build bigger, stronger arms."


Trainer of over 400 Olympic athletes, Olympic medalists in 17 different sports and numerous bodybuilders and stars of the NFL and NHL


"Grip strength is critical in CrossFit and Fat Gripz have helped me massively."


CrossFit Champion


"A big limiting factor in CrossFit is your grip strength affecting everything from olympic lifts to pull-ups - do as much axle bar or FatGripz work as possible to fix this."


Olympic weight lifting champion and CrossFit expert


"If your back and legs can dead-lift 700lb, but your grip ends at 300lbs, your dead-lift is 300 lbs. When it comes to strength, you are only as strong as your weakest link and most strength athletes know that fact all too well."


Strength trainer for US SWAT teams


"Fat Gripz are my favorite grip tool - my forearms are on fire when I use them!"


Brazilian JuJitsu World Champion


"Fat Gripz hit every fiber and will blow your arms up like never before."

Chin-ups using Fat Gripz for MMA training

Grip strength is essential in MMA. Grapplers need a very powerful grip but standard barbells and dumbbells are too skinny to help them develop the strength in their hands and wrists. Fat Gripz, however, are different. The thicker diameter is much closer to the size of a person's wrist which makes them perfect for developing grip strength for grappling.
