Just photographed the founder of CrossFit Endurance, Brian McKenzie as he worked with Kelly Starrett during a workshop specially designed to teach a select group of Navy Seals how to improve their bio-mechanics. A CrossFit celebrity in his own right, Brian introduced short, high-intensity workouts to endurance athletes with eye-opening results.

What I think is interesting is that in just a handful of years CrossFit has gone from a garage workout for crazy fit athletes to having a world championship on ESPN and being featured in Reebok ads to being used as part of the Navy Seal training regimen.
