Hey everybody, I am happy to be here to find a little advice on my life long passion to practise MA. I am now 39 and I feel more like a ninja than ever. I am very fit, totally inspired, balanced are devoting myself with love to learning 24 form tai chi. I am about half way through memorising the 24 set. (single whip is where I am) I try to practise very smooth and flow gently. And beleive it or not I have developed a minor lower back ache. I am totally astonished as I play high level hockey, surf like a free man and build stages for a living needless to say I am not chuck norris but feel I could out wit most ninja'a out there. I think I have pinpointed the motion that has caused the my slight discomfort. In brush knee when we twist our body a little just before steping? Or the slight turn in parting horses main before moving forward. I hope someone can share some wisdom other than get a good teacher and I will one day but for now I am reading, watching video's and focusing with all my being to do the tai chi I can with my resources at hand. Thanks and may the force be with you.
