Anybody can tell me the difference of these two.... On the spinning does the lead foot move to the right then spin right around (in a right hand stance) How does it differ from a crossing back kick thanks Also, another question What is being said when stances are being switched ... when my sensei calls out 1 , 2 , 3 for the left side..... he then yells something that sounds like, "ACEsh!!!!" or something then everyone switches the stance from a right hand to left handed thanks for any help peace
