Training has to be a way of life. The thing to remember is that as you get fitter your body actually wants to do less and less when you really want it to do more and more. This is why it is difficult to maintain the discipline required to stay fit. There is a trick to this every martial artist knows. Before you get into your training for the day start with a routine. It can be anything from basic warm-up exercises to dance moves, jumping on the spot or simply shadow boxing at a very relaxed rate. This is becomes your “key”. The moment you start to go through it you take your mind in the headspace required to let your body focus and perform.
