At present, I have been practising Kung Fu's Phoenix Eye. I'll not go into detail as it is very dangerous to the unsupervised. It is for attacking soft tissue areas to limbs and nerves, and I feel it is true empty hand combat at its peak. It is almost as if you have a weapon all of a sudden without really having one. Conditioning is a must like you can see from the photo, conditioning in its self can be a form of anything in which serves you stronger in any area of your life, not just martial arts.
