The strongest hands I’ve come across have been on laborers.
This has led me to view gym advice for grip as terrible.
Every laborer built their hand strength up with lots of work daily, in gym terms massive time under tension, massive volume, and high frequency.
I own the 100-350 set of Heavy Grips grippers.
Sometimes I can close the 200, and I can rep out with the 150.
For awhile now immediately before laying down to sleep I attempt the 200 right handed with varied results from doubling a solid close to being a good inch from a close. I then give the 150 a good squeeze with each hand, and lay down.
Having went to the gym earlier in the day, and not wanting to lift outside in the dark I decided to have a fun session with the grippers.
I started with partials and negatives with the 200.
Then I repped out the 150, followed by repping out the 100.
Then I switched hands.
That was the first drop set.
Five minutes later I did a second drop set where I allowed some rest switching hands with each drop in gripper size, additionally doing the 100 inverted to end.
It was fun for me, I got a good pump out of it, and it was easy as can be logistically.
Despite literature saying not to train grippers like this, I think to truly get the 200 consistently, and to then advance from there, I’ll keep getting more and more reps with this approach.
There are anecdotes on forearm forums saying this approach worked for them, and this is how I’ve always treated pressing via pushups.
Do enough volume and the body builds top end strength.
Relatedly as a teenager I’d watch the Jean Claude Van Damme movie “Bloodsport”, turning it into a workout doing lots of reps of calf raises, and with the 100# gripper.
I’d even got my buddy in on it once.
Make training fun, and you’ll do more of it.
Do more of it, and you’ll get more results.
