BJ Penn’s training for Diego Sanchez (UFC Countdown)

This is from the UFC countdown training preparation section that BJ was doing for Diego Sanchez. I essentially trimmed it down to the more interesting part which was his nervous system training exercises. It’s quite unique and explains a lot about how they turned an already talented fighter into a well disciplined machine. If you watched his fight against Diego, you pretty much know that BJ gave, arguably, the best performance of his career.
