Rickson Gracie Documentary Choke
Rickson Gracie in Choke a Documentary about his training for Vale Tudo 95
If you haven't seen it yet, it's a documentary on Rickson following him and some of the other fighters as they prepared for the Vale Tudo 95.
This was a no-holds-barred tournament with no weight divisions and a fighter would have to win 3 fights in one night.
It gives some amazing insight into Rickson's training and his mental preparation leading up to the event. Even if you've seen it it's worth watching again, I always pic up new details and insight every time I see it.
