David Funk has always lived an active lifestyle., with a 20 year career in entertainment doing stunts in live shows and film, fire performance, sideshow, and various circus acts all over the U.S. and Mexico. The simple goal, "Keep Moving" made a natural transition into the world of fitness. However, it wasn't enough to JUST work out, it had to be creative, playful, fun. The world of Parkour, OCR (obstacle course racing), and NOC (ninja obstacle course) was just that. He is a level 3 certified instructor for the World Freerunning and Parkour Federation; a course tester for "American Ninja Warrior", 2016 UNAA semi-finalist, and 1st place winner of Camp Rhino's "100 Obstacle Challenge", among other top rankings in ninja and parkour competitions. Yet, he still maintains that he's just "a big kid on a giant playground".
