Rogue Fitness Cannonball Grips

Standard bars allow for a closed-hand grip, which relies heavily on your thumb and palm. The spherical shape of the Cannonball Grips forces an open-hand grip, which shifts the demand to your fingers and forearms, significantly increasing the difficulty of your lifts and pull-ups.

Yes, the included heavy-duty straps and carabiners are designed to loop around most standard pull-up bars, power rack crossmembers, or even kettlebell handles. As long as you have a secure anchor point that can support your body weight, they will work.

A 3-inch diameter is considered a standard size for grip training, but it is quite challenging. If you are new to grip-specific training, expect a steep learning curve as your hands adapt to the open-hand position.

The steel construction and powder-coat finish are very durable. You can wipe them down with a damp cloth if they get dusty or chalky, but they generally require no maintenance beyond standard gym equipment care.

The powder coat is specifically applied to provide a consistent, slightly textured surface that helps with friction. It is designed to hold chalk well, which will further improve your grip if you find the surface too slick during intense sessions.
