Hello. I need help with using defense. I've trained under Hayashi-ha Shito-ryu and Shudokan. However, when sparring I find that I use almost zero blocks. I would like to improve my blocking. I know several blocks including Gedan-barai, Age-uke, Soto-uke, Uchi-uke, and Shuto-uke, however I seem to never use anything except the occasionaly Soto-uke to open up room for a strike. I tend to stay in cat or snake stance, and I fight a low-medium hit game. Help?
