If you have ever participated in an actual battle, know that when the time comes, are not looking for the bells and that at best can be launched a couple of kicks before reaching distance fists and demolitions. In this second part of the "metric" Jim Wagner we focus on the beatings and blockades with the legs. As with the arms, we see that there are only 10 primary directions to attack with kicks and knee strike and know the three techniques to block. The reality of the street does not require hundreds of mastering techniques, but simple formulas to help us survive. So is the system of Jim Wagner, based on reality.
