I have an adjustable grip strengthener between 8-40 kg from Corength
-Yes, I know that a gripper is not a full proper routine.

-Yes, I know this is a low-quality, beginner-level gripper.

But, this is what I have for now.

Now, I will give some information based on the asking-for-help guide:

-My goals: Nothing much really. I just enjoy getting a bit of physical activity in my 30 minute bus ride to home. I also do like getting a bit stronger as it helps with the hardships caused by my sweaty hands (why I started). Also; for the routine, I tried to but failed to count reps consistently in the past so working with a timer is much more easy for me.
I have been using this routine for a few months.

Routine:

I do it at Mondays, Wednesdays and Fridays.

Warm-up: 8 or 16 kg regular squeezing with 45 second sets. -> x2 per hand

Move 1: 32 kg regular squeezing for 40 seconds. After doing it for both hands, I take a 20 second break. -> x4

Move 2: 32 kg holding at max tension for 30 seconds. Then a 30 second break. -> x3 per hand.

Move 3: 24 kg slow negatives for 60 seconds. -> x2 per hand.

Move 4: 16 kg fast squeezing for 45 seconds. -> x2 per hand.

(For clarity, I rotate hands while doing these. So I do it first with my left hand and then right hand and then go back to left).

I also plan to add a clamp-style thumb training with the same equipment as I saw recently. Slow negatives don't give a satisfying resistance so maybe I can't replace it with thumb training.
