3 main types of grip strength:1) Crushing (like a Captains of Crush gripper)2) Pinching3) Supporting (like a deadlift)
I knew a guy that weighed about 250lbs. His stick was that he could grab your skull with one hand and make you scream uncle. I saw it time and time again. Guys doubted he could do this and would volunteer. He would palm their skull like a basketball and squeeze. The screaming was instantaneous. He had some serious innate grip strength.
The guys on the sides aren't pointing towards him, not gonna watch.
Hard to gauge anyone's strength, everyone has different ROM, same as grip, larger hand is such an advantage, I think a strength feat of pushing something is more true strength
Practical and useful strength.
weird curling is the true strength test
