The Global Defense System is the result of the study of several martial arts and combat sports. It is not a new style but a concept that focuses on open-mindedness in practice. Staying compartmentalized in a practice can be very harmful during a fight because no discipline contains all the aspects of the fight. In this Cross Training with Bare Hands DVD, we will see a global approach to work, trying to give a guiding idea more than frozen techniques because adaptability remains of paramount importance in combat. The concept of distance plays an important role as well as movements. The techniques come from DBMA, Panantukan, Jun Fan or different boxes, but are complementary to each other promoting adaptability and providing solutions to various situations.
