Improve your grip for Hapkido with Hand Grippers
Hand grips are a compact and portable piece of equipment
that is great for increasing your grip strength.

2/ For speed repetitions, hold the gripper and try to close it
as many times as you can for a set amount of time. Repeat with the other hand.
Make sure to maintain the amount of time with each hand, and pay attention to
the amount of pressure you’re exerting on each grip session. This exercise is as
much about quality as it is about quantity.
