Rickson Gracie is the son of Helio Gracie, founder of Brazilian Jiu-Jitsu. The Gracie Jiu=Jitsu style changed the sport of Mixed Martial Arts, showing the world that proper leverage and submissions were what won fights, as many fights eventually ended up on the ground.
Here are a couple clips from the documentary Choke, where Rickson gets ready for the Vale Tudo freestyle fighting tournament in Tokyo. He embodies the Movement Mindset style of movement, flow, mental preparation and breathing in this video. Enjoy.
