The founders of Kapap Academy, major Avi Nardia and Albert Timen, have made this video to show us the methods of fitting-out for combat. They will teach how to explore and develop mental resistance under stress situations (training under water, simultaneous attack by many aggressors). In the physical part, through series of exercises and ground applications specifically developed for Kapap by John Machado, we will learn to improve balance and resistance, and we will know the most significant contribution in recent years to Kapap system, the result of Cross-Training and Brazilian Jiu-Jitsu: the principle of the relative position. It is an essential work, because the art of war consists firstly on learning how to fight.
