Here comes another simple, yet effective, DIY. Today’s items will help you build a stronger grip, which is useful for everything from deadlifting in the gym to shaking hands in an office introduction. I’m going to show you how to make cannonball/grenade ball grips and a pinch gripper.
Let’s start with the cannonball grips. I got some softballs for $3 each, eye bolts for less than a dollar each, and I had some left over tee nuts from fixing up my flat bench.
Begin by drilling a hole through the softball. Be careful to drill straight through the center of the ball. I used a 3/8″ bit to match up with my 5/16″ hardware. Now, with a flat washer near the eye, push the eye bolt through the hole in the ball. Put a tee nut on the other end to receive the bolt. Tighten it up, and you’re good to go!
For the pinch gripper, I used a hockey puck I had lying around. Same story here: 3/8″ hole through the middle, but this time the eye bolt had a nut and washer on the eye-end. I used a tee nut on the top side, threaded the eye bolt into it, then tightened the nut on the other end to cinch everything together.
I made a pair of cannonballs for doing pull ups, and either tool can be used with the loading pin for single-arm work.
Give these tools a shot and let me know how it worked in the comments or over on the Facebook page!
