Thick-bar training has gained traction over the years, and for good reason—it rapidly improves grip strength and overall strength.

You’ve probably heard of training tools like TylerGrip, Fat Gripz, EZ Grips, and Grips FEAR attachments. But there’s another way to challenge your grip and forearms: use kettlebells… in an unconventional way!

How to Perform Cannonbell Curls

Instead of gripping the handle of the kettlebell, grasp the cannonball portion and curl away. This forces you to maintain a strong, open grip, engaging your forearms and biceps in a whole new way.

✅ You can only perform supinated (palms-up) curls using this method, but the feel is incredible.
✅ Try them standing, seated, on an incline bench, or using a preacher bench.
✅ The instability of the kettlebell makes your biceps and forearms work overtime to control the movement.

Give cannonbell curls a shot—you may just find them to be a powerful alternative in your arm training routine!
