YouTube - Fedor - The Baddest Man on the Planet - Part 1
that is part of a documentary that gives a little insight into his mind set.
you will never be able to copy what he does for his fights as it is set to the individual.
some people like to hypew themselves up other like to stay calm like fedor but it all comes down to what they have found to work best for them.
find you own style that works for you.
