I tried circuit training after watching Rich Franklin. It's pretty intense as it is...add a mask. I think that's one of the reasons why Wanderlei could keep the blitzkrieg pace for so long.
Three minutes is a good length of time. Five minutes is an eternity. It's the strangest thing. Anything other sport five minutes is like a few seconds, but when you're training, sparring, fighting...it's a LONG time.

Baked, not fried... the healthy choice.
