Ronnie Coleman almost closed a number 3 captains of crush gripper on his first try. That is pretty good, considering he probably doesn't train his grip. I don't know what kind of numbers he is putting up in the gym,but to almost close a 3 on your first try, that is impressive. I heard that Dorian Yates couldn't even close a number 2 on his first try.
A number 2 is around 195lbs of crush, a 3 is 280lbs of crush. When your hands are strong enough to close a 3, you can probably crush a closed can of beer or whatever kind of liquid in your hand.
The next level up is really serious the no. 4. Magnus Samuelsson is one of few men, who can close it and he can crush a raw potato in his hand.
