That's a bunch of crap. Anybody who saw the 3-week series of GSP/Penn knows that GSP doesn't drink and his only real vice regarding diet/training is he eats McDonald's on occasion.
We already know Josh Koschek stays in shape all-year round because he took the fight so short-notice with Thiago Alves.
Other fighters whom I guarantee stay in shape all-year round as these guys are always training others in MMA or wrestling:
- Matt Hughes
- Frankie Edgar
- Shane Carwin
- Kenny Florian
- Randy Couture
BJ gets done with a fight and just doesn't work anymore. BJ and Terrell Owens are the biggest sore losers on the planet.
Some people just stay in shape all year around and some people don't.
