Overview

Fat Gripz Pro are thick-grip attachments that clamp onto barbells, dumbbells, cable handles and machine grips, increasing the handle's outer diameter to 2.25 inches to force greater forearm and grip activation. This Special Edition swaps the original blue for black with blue lettering.

The core idea, a thicker bar demands more forearm and grip work, is why lifters and physical therapists have used fat grips for years. One experienced reviewer, who tested this alongside three competing thick grips, cautions that at 2.25 inches this is the more advanced size and beginners should start with a thinner grip before working up to it.

  • 2.25 inch outer diameter thick grip pair
  • Fits barbells, dumbbells, cable handles and machine grips
  • Bevelled ends fit angled EZ bars
  • Black Special Edition finish

Who it's for

Good for lifters who already do standard barbell and dumbbell work and want to add grip and forearm demand to existing lifts, pull-ups or curls. Not the first thick grip to buy for someone brand new to grip training, since the 2.25 inch diameter is on the aggressive end.

What buyers say

From Amazon customer reviews.

Buyers say the grips noticeably increase forearm and grip fatigue on curls, pull-ups and rows, and describe them as durable enough to expect years of use. The one point of caution, raised by a reviewer who tested several thick-grip brands side by side, is that the 2.25 inch Pro size is better attempted after building up with a thinner grip first.
