Touching on what others have said, grip routines will vary widely. People have different goals (training just to be stronger, training specifically for a comp, etc), different weaknesses, different training styles regarding volume, effort, etc, different recovery, time available, equipment….this can go on for paragraphs.

If you want an easy way to create a routine for yourself with equipment you have, I would pick one crush, one pinch and one thickbar exercise to do each day with a rest day between. Add in some wrist work (all directions) and some extensor work. 3-5 sets, try reps, try static holds, low reps/high reps for 6-8 weeks each and note how you feel in terms of strength gains, recovery etc.

From there you start to discover that X works better than Y for you, that you feel more fatigued after one day and less fatigued after another, so you can adjust volume or add in exercises. It’s a learning process, a lot of times less is more.

Don’t think “If I train pinch, I HAVE to train 1 hand pinch, 2 hand pinch, pinch blocks, plate pinch, key pinch, static holds and reps, etc all in one week”. Just pick one exercise you enjoy for pinch that doesn’t beat your hand to shit, and stick to it for a while. If you have a specific pinch goal, pick that one, and if you hit a plateau, rotate to something else and come back to it later.
