We’ve learned that harnessing the natural camaraderie, competition and fun of sport or game yields an intensity that cannot be matched by other means. The late Col. Jeff Cooper observed, “the fear of sporting failure is worse than the fear of death.” It is our observation that men will die for points. Using whiteboards as scoreboards, keeping accurate scores and records, running a clock, and precisely defining the rules and standards for performance, we not only motivate unprecedented output, but derive both relative and absolute metrics at every workout.
