As soon as CrossFit added a clock and a score to its workouts it was inevitable that it would become a sport.   This is human nature.   If there is a score then that means I can be better than someone else and therefore I can win.   This is one of the fun parts of CrossFit.  Fitness had never been this much of a competition before.  It is one of the two biggest reasons people are attracted to and stick with CrossFit over other workout protocols.   Most of us are competitive at some level, and at a higher level than some of us might want to admit.
