I like Sundays as I get up early and can go practice my Filipino Tia-Chi early in the morning. I find the morning is peacefull and I can work my own Sayaw while it is still quite. I can take the time to explore each movement and study it. It is good to back and play hard and it is good to flow through and build your internal energy. I feel that there is not enough of the internal side taught  with most FMA styles today. I believe that it is as important as all of the rest. I have heard that the old Masters in Hawaii and the Philippines could make their energy flow though the tip of their stick when they hit and when they moved them. I believe this is true. I know the Chinese masters had many exercises to practice this side of the art.
