I agree with you, Dan. I like the quote, and personally I believe it. Train hard. Let that mean what it needs to mean for you. If you think extremely rigorous (physically demanding) training is wrong, then don't do it. If you feel that rigorous training holds some benefit for you, try it. Why does it have to be more complicated than that?
