“Greg Amundson is about as motivating and motivated a human being as there exists. I met Greg in 2007 and his energy was immediately infectious. Not only was he probably the fittest guy I knew of at the time, but his lifestyle and way of coaching were one of the first I've ever known of to encompass a true holistic approach for the mind, body, and spirit that welcomed everyone in. Greg has pieced together the principles of weight training, sport, CrossFit, yoga, meditation, and nutrition. I just don't know too many other people doing it, not too mention on this level.”
