I never thought that breathing would be so important in the martial arts. This is the legendary Rickson Gracie, who is arguably undefeated in over 400 fights.  And while he is not as famous as Bruce Lee, the aura surrounding him is just as strong in the eyes of his students and opponents. He was the strongest fighter in the strongest martial arts family for a very long time.

By the way, anyone who has read the old Destroyer series knows that the key to being the best assassin in the world is … of course… breathing.

Gracie claims that breathing technique is the key to all of it, stamina, strength, concentration. Very interesting to watch his technique, but I will have to practice a lot to be able to do it. 6:51
