Why "nerd"? I know plenty of "nerds" who are in great shape, and plenty of "athletes" who only have the ability to perform within a limited range of activities - that is, those specific to their sport. Is conditioning important? Certainly. But while I have been encouraged and guided by caring coaches, I have never been chewed out by one - only by coaches who cared more about the performance of the team in the upcoming competition than they did about the health and well-being of the athletes.
In addition, this thread is about the possibility of martial arts being taught in school - and as a school teacher and martial arts instructor, I can say that I get much better results, in both environments, as a supportive coach with high expectations than I do "chewing people out".
