The grip motion utilizes slow twitch and fast twitch muscle types so conditioning, nutrition, and rest are your playbook. Grip strength involves 10 different muscle groups (3 in the forearm and wrist, 7 deep/superficial groups in the hand) and thus requires different types of activities (finger extensions, crimping, clamping, pinching, crushing). Overuse injuries occur when consistently exercising one strenuous technique without allowing your muscles and more importantly, your tendons, to heal themselves. Tendons take a very, very long time to recover. If you are unsure if you have rested enough, you absolutely have not. Overuse will inevitably lead to wrist and elbow problems. Also, never ever work out your ring finger by itself. There is a muscle group that connects your middle finger to your ring finger and it can be torn easier than you would think. Those two fingers are the core of your grip so they must work as a team. Always stretch thoroughly before and after each exercise as you will definitely get an instant flash-pump if you're doing it correctly.
The most effective and difficult grip exercise for brute strength is the open hand pinch. The more difficult it is to hang on to something, the better. I used to hang onto dumbbells by the top/bottom or stacked barbell plates until failure. There's something about dropping items that bring the "the floor is lava" episodes of our childhood back and help us to push ourselves harder.
A good technique for closed/crushing stability and grip strength is simply hanging from a pull-up bar, door frame, or similar structure until failure.
After each exercise, counter the movement with an opposite technique (finger extensions, circumduction) to prevent injury. The best way I found to do this is to first, fill a bucket or large jar with flour, dirt, sand, rice, or the like. Then, insert your fist and open your fingers and repeat. Another exercise is to hold something small and heavy like a shot put ball and rotate your wrist in a circular motion.
Grip strength is very important and there are various studies that found it is a excellent predictor for total muscle strength, diet, vitality, and can even suggest your potential lifespan. Weaker grip strength has been linked to higher mortality rates whereas stronger grip strength was found correlating with higher cognitive function and higher hemoglobin levels. Crazy, huh?
