I think that the question of Kick-ins could encourage a great debate between martial artists. In all of my years of training I have never actually seen a kick-in or whipping done in real life so therefore it would be wrong for me to comment against it. I have seen a kick-in on a video (“worlds strongest karate”) and the poor guy said that he had had enough and they threw him back in for more. For those of you that have seen it I am sure you know what I mean. I do think however that the question has to be raised as to what benefits derive from it and from reading some of the posts above it seems that it can be quite pointless.
If you have just spent two years intensely training for a specific grading to acquire a black belt from first kyu, you have put in the hard yards to the first advanced level. This to me says that you have stuck around and that you take your art seriously. Let’s just say that you have successfully completed a five hour black belt grading that has just taken the best part of your physical and mental abilities. Why would it be necessary to then have an all in ‘see if you can defend yourself’ kick-in to finish it off, especially when the sparring would have made up quite a chunk of your actual grading anyway. I can’t help but think that it is an “I am still the boss” method of grading completion. I can see that it may be a test of spirit but is it necessary?
