Quotes from the same author

If there is one abiding theme in the gym, it's the withering work in the ring. Those not fit do not survive.
 Emanuel Steward
The state of mind of a fighter is so important. I don't like to see a fighter stay locked up in a room. Sometimes it works against them. They think and they worry. They dwell, sitting in that dark room. You come back and they're psyched out. I like to see boxers eat and then walk, mingle with people. You have to have a certain amount of movement.
 Emanuel Steward
