The third video this week features more recent footage from the dojo on the subject of entangled arm locks from Naihanchi Kata and progressing on to how they may be abandoned if things aren't going to plan.
Although joint attacks should be considered only as a support strategy for self-defence (the primary strategy being of course percussive impact), in my opinion, they should nevertheless still be studied as part of a holistic combative methodology.
Joint attacks like those featured here are found throughout the classical karate kata and knowledge of the principles associated with such applications against the human body is always valuable. Again, the underlying principles are far more important than the specific techniques.
Again...hope you enjoy!
