hey xnfx, in reply to your question i would offer this first if you are getting ready for your first big match if you think your match will last 15 min train as if it will last 60 min you want to be well overly prepared I assume you have a trainer that should be able to assist, if you dont have one get one, you need someone outside the ring watching the bad habits blossom as you get tired do the hands drop? do you start to lead? so on and so on as far as deep breathing, great questions i would suggets getting some reading material "empty force" by paul dong comes to mind start with a quiet setting with no time frame, get comfortable and relax make sure you have no distractions, i find its best to be alone or where no one can see you. start slow and as time passes you will be able to do it for longer fyi- you may encounter body shakes and other strange electric sensations as you begin to change chi into jing good luck with your upcoming match, keep the hands up...lol
