Mental strength is an essential element for martial arts like Karate. Victory or defeat might already be decided before the actual fight. If a fraction of a split-second decides the outcome of a fight, the mental training must be professional.
At the winter Olympics in 2006, Turino, I was member of the team Martin Annen. We won two bronze medals, mainly due to our mental strength and Rinaldos preparation. There is no question about Rinaldo Manferdini supporting us in future events.
