Atos black belt Josh Hinger has got a tough job ahead of him this weekend at the IBJJF Chicago Summer International Open. 

Last year Hinger took quadruple gold -- that's gold medal in his weight class and the absolute division, both gi and no-gi! 

Hinger competes at middleweight and trains out of the Atos HQ in San Diego alongside head coach Andre Galvao and all the world-class athletes including Keenan Cornelius, JT Torres, Lucas 'Hulk' Barbosa and more.
