Everyone is nervous before they fight whether they say they are or not. As soon as you step into that ring it all goes away. It's just you and the other guy.

Like someone previously said get lots of roadwork in. You can never be too fit! Try running 5/6 days a week a couple miles as well as your boxing training. There is nothing worse than being unfit and tired after the first round and your opponent taking advantage of that. Trust me!
