From my experience in PMA they teach you how to defend yourself but no contact to the human body so i give it a solid 1.

I first came to PMA to learn self-defense & to get into shape. I have gotten so much more from the traditional philosophy of this school. Besides developing karate techniques, I have delved into Japanese culture and have woven it all into my daily life. Give it try, you just might like it as much as I do!
