Why do boxers wake up at 4:30am in the morning to run?

^Good answer.

I always wondered this myself, surely if you are putting your body through the kind of physical and emotional stress one goes through while training for a fighter, a good night's sleep would be essential.

I think its a psycological thing.

I preffer a good nights sleep tbh.
