NEVER BEEN TAUGHT DEFENCE? Switch clubs man. It's all about YOU, not them taking your money and showing you how to be flashy. You need to be able to properly defend yourself.
If you are friends with folks from your current club, then simply return after you have progressed a little bit and show them what you've learned.
this. good defense wins fights. as im sure you have seen ONE hit can end a fight so you being able to NOT GET HIT needs to be main priority ''protect yourself at all times''.. id speak to you coach if that doesnt work switch clubs asap.
