Hello Vacaville, I’m Phil Jamison, a 2 time American Ninja Warrior competitor and the owner and founder of Stone Core Ninja Fitness Academy. At Stone Core we offer a genuine American Ninja Warrior experience for ages 4 and up. Our kids program is a powerful value-based system that supports kids in gaining a stronger sense of confidence and self-worth, all through the process of Ninja Warrior training. In addition, we factor a 5 Core attitude system that works in harmony with the process of overcoming ninja warrior obstacles. These attitudes are courtesy, integrity, perseverance, self-control, and indomitable spirit. As a Ninja Warrior and prior military service member I consistently and persistently aim to demonstrate to youth how live in accordance to these five core attitudes, which resulted in me becoming the first official runner of American Ninja Warrior season 9 & 10!
“What you get by achieving your goals is not as important as what you become by achieving your goals.” -Ninja Warrior Logic
