If a Fusion student kicks a tree in the woods and there is no one there to hear it, does it make a sound? No but the student better if they are training for their blackbelt! Thats what happens when you are blogless in Portland. Bad jokes :) On that topic though I do notice now that my martial arts has sound. I also notice that it improves my training and execution to make sound and exhale on my punches, kicks, forms, or for no reason at all. Honestly didnt get it when I started. I appreciated the concept but not the application. To understand the application is a plus and to continue to develop my sound, I trust, will improve my outcomes.
