"So the training was physically challenging, but not by any means brutal. There was no shin-kicking of steel pipes or picking up steaming cauldrons with ones for arms wait, thats Kung Fu. Anyway, the training was intense but not particularly high-impact. There seems to be an implicit understanding that training, like an actual bout of Thai boxing, is an endurance game. In other words, while being able to go balls-out is valuable, one must also learn to pace oneself."
