One of the great elements of Krav Maga is that it takes in good ideas from wherever they are discovered, and lets go the bad.
Mark Kaufman wrote a piece on the importance of Proper Punching technique & how he studies and incorporates lessons learned outside Krav Maga to be a better Krav Maga Instructor:
Many of the arts can teach us lessons we may have forgotten and breaking down the movement is students need sometimes, Those of us experienced take movement for granted, we do things unconsciously and although IKI Krav Maga continues to move forward (Yea!), we must still pay attention to the basics.
What is a creative way you have taught a lesson to someone else?
