I caught a bit of Fight Quest today (can't even remember the channel). Where two American fighters go around the world and train in various fighting styles. Today was an episode where they were in China (i think) learning a bit of the Wushu style.
Two great moments - one of the fighters went to a temple to live with and train with the Monks and about 30 seconds into training with the Master he "uncovered" his inflexibility and he suffered greatly for it. (and he was very asymmetrical - right being much tighter)
Then when leaving the temple the Master told him (paraphrasing) "Kung fu does not matter - developing the spirit is what matters."
Now this went right over the head of the fighter who just wanted to "break peoples noses".
Just found it interesting...
*Added today - point being with the info above...
Mobility/flexibility is a foundation for whatever you do. Laying the foundation for your training (whatever that is...) is important.
