hmm well from what i read in that thread i am pretty sure my school is ITF but im not qute sure cause some of the WTF stuff i read there i do too so i dont know
could someone please explain what these are cause ive been doing TKD for 3 years now and b4 i came to this forum i had never heard of any of this and if there has been a thread about the b4 im sorry i didnt see it
maybe im just stupid but i have no clue what the sinewave is so if anyone would send me a link to a site or even xplain it themselves that would be great thanks
