Wouldn't know, don't do kick boxing, and I the last time I did TKD it was not yet an Olympic sport. All I can tell you is the "ready stance" is different from TKD, don't know about kick boxing
I've had Guru Ron's JKD video series for a long time now. Went to hunt it down last weekend and could only find discs 7 & 8! Gotta do some more searching!!
