Let customers speak for us
These grips are truly transformative for providing biofeedback while lifting weights. The cushioning enhances grip and activates the muscles like never before. I'm absolutely thrilled with my new grips!
GripSleev is absolutely fantastic! I’ve tried countless fitness products over the years, but nothing has boosted my grip strength like this. After just a few sessions, I can literally see and feel the veins and muscles in my forearms popping — the results are unreal!
the gripsleevs worked great and had my muscles burning from the beginning. Definitely going to continue to use them and recommend to anyone looking to take their workout to the next level.
Extremely helpful for my hand weights, thank you
Using the GRIPSLEEV is an awesome enhancement to my workouts. Super quick and easy to apply to any bar or dumbbell and immediately noticeable change in grip strength and muscle activation. Highly recommend adding to your gear!
Honestly greatest grip trainer I've ever used!
