In this video the Great Master Tatum, assisted by Masters Luelmo (7th grade) and Camacho (6th grade), representatives of LTKKA from Spain, Portugal and Italy, develops the techniques called "Freestyle". With these techniques the practitioner will gradually learn the structure and will understand the process of formulation. As for personal defense techniques, there are four basic ways to face the opponent in combat. However, instead of naming the techniques, in freestyle they use letters and numbers to identify them and to create an equation for the combat, whose formula will allow us to chain movements.
