"The strongest factor in conditioning is sex, in the sense that the first thing that a person is really taught is whether they are male or female."

Previous Quote

Fighters are afraid of conditioning, they are afraid of getting tired, but I don't want to have anxiety or be afraid of anything. I can go 100 percent out there and never have to worry about getting tired. Everybody says fighting is 90 percent mental, and it's true. Knowing you can go 15 minutes or 25 minutes without any problem can help you sustain that mental advantage over your opponent.
