Only I know how hard I trained. I left my family, my girlfriend, and the people I love in Brazil to train in the United States with 'Macaco' five or six times a day.
I injured my neck in training, but did physical therapy and thought everything was fine, but when I fell against the cage everything went numb, I couldn't feel my body.
You do have to fight different when you might have to fight three times in one night. I really like fighting just one time a night, this lets you do more things.
