If you are serious about building over all strength, you should not neglect to develop your hands and forearms. The stronger they become, the more weight you can lift when working out with barbells and dumbbells.

1. Grip Strength With Homemade Tools

2. Gorilla Grip Strength
If you are serious about building over all strength, you
should not neglect to develop your hands and forearms.
The stronger they become, the more weight you can lift
when working out with barbells and dumbbells.
There are as many ways to develop your forearms as
your imagination can think up; a lot of the equipment
you can use can be homemade.

3. For pinch grip workouts you can take a softball and drill a
pilot hole part of the way into it.
Next screw a lag hook into the pilot hole.
You would then just run a small chain through the hole in a
plate or loop around a dumb bell and hook the ends of the
chain onto the hook.
Hold the ball with a full grip or just your finger tips and lift.
Add more plates or a heavier one for added weight.

4. A variation would be to use a hockey puck.
Drill a hole into the center of the hockey puck and screw in a
lag hook.
For a stronger setup insert an eye-bolt through the hole with
a washer on either side of the puck with a nut on the top side
to hold it together.
This is a great finger tip pinch grip tool.

5. Two inch thick patio stones work great, you can get them
from about 12” x 12” up two 24” x 24”.
If you have two of them, you could carry one in each hand
and do a farmers carry to get more of a whole body
workout.
Squeezing and holding on to patio stones really gives your
arms a excellent workout.
