The Columbus, Indiana native runs his own lawn and landscape business, “mostly mowing with a gear drive walk behind Scag mower.  It is driven from the gearbox to belts which are tensioned or held onto with two springs that my hands have to pull up to turn.”  When it comes to his world-class grip strength, Jonathan says, “I give this a lot of credit.”  Jonathan said that he is starting to compete in armwrestling now, where his powerful grip will be a huge asset.

In memory of Jesse Marunde, “the first teenage Captains of Crush,” IronMind® pledged to contribute US$500.00 to the educational trust fund for his children each time a teenager matched this tremendous feat of strength, and since Jonathan is 19, his great grip strength is helping Jesse Marunde’s children, for which we thank him.

Congratulations, Jonathan - you proved you have world-class grip strength and you are now certified on the No. 3 Captains of Crush® Gripper, and if that’s not enough, you’ve also helped out Jesse Marunde’s children.  Way to go!
