without the mental, the physical is twitching fibers with no direction.
as a former competitive ahtlete, my bia is to the mental, it was a huge part of a winning game: visualization, determination, persistance, confidence, etc.
anyone watch "The Contender" last night ? A smaller, less powerful boxer used his mental game to outsmart and defeat a larger, more powerful boxer in the ring. One interesting episode in an otherwise trashy show.
