Welcome to Gaia! ::

remember that the best way not to get hit is to end it as fast as possible (run away or make the first strike)

there are various ways to do it. wolfs way is good. some other ways are just to have a sparring parter through various techniques at you and you try to block them. remember you have to be fully trusting in your techniques. if it didnt work them martial artists wouldnt teach it. so try to get into the mindset that if you know it will work then you dont need to be worried. it is natural for the body to tension up. but keep it loose as well. also like i said you need to have a good sparring partner. someone you trust. a best friend a sensei someone to that nature. someone that you know wont hurt you. that does help. once you get to the point where you are relaxed with a sensei or a friend then you will be relaxed if you need it in real life or in a tournament or wherever you take your martial arts. if you are a beginner then dont worry. skill comes with time. if you are advanced then you just havent had enough time. im a 3rd degree black belt in ninjutsu, i still make mistakes. all blackbelt mean is that you are an advaced beginner. so dont worry if you mess up sometimes. you will get it. if you have anymore questions please feel free to pm me.
