Kim Bum-suk told IronMind that he could close the Captains of Crush No. 1 gripper the first time he tried—fast forward and today he has been certified on the Captains of Crush No. 3 gripper, going from being respectable to world class grip strength in four years.


He told IronMind that working as a mechanical engineer, he uses his “hands a lot at work.

“In March 2014, I fully closed the No. 3 with a credit card set on my first try. Before that, I just trained with a wide set.

“I train twice a week and I prefer to do many reps with a weak gripper.

“My future goal is close the Captains of Crush No. 3.5 gripper,” said Kim Bum-suk.

Congratulations, Kim Bum-suk: you have proven that you have world class grip strength and you have been certified on the Captains of Crush No. 3 gripper. Many thanks to Koo Hyoungtae for serving as the referee on Kim Bum-suk’s official attempt to close a CoC No. 3 gripper.
