You really don't see any differences between exo match and regular tournament?
You really don't see that what keeps a player healthy is how he manages his off time and how he sets his training schedule for tournaments?!
After all, an exho isn't just going there and having fun. There is travelling, media appointments, greeting fans, breaking out of your training schedule/ routine. In other words, despite being called "exhibition" it is "work" for the players involved.
