It is the most powerful submission in the sport. It is a beautiful thing. You're holding them into you, their back is on you, and you are basically choking them gradually like a boa constrictor and once you've got them, the pressure goes on and they have to submit or they are going to stop breathing. It happened to me early in my career, and I panicked, and gave in, I tapped out too early. I learned a lot from that. I learned from it, learned how to do the move better, learned how to avoid it being done to me.

The surface below your feet is so special. It is not like a boxing ring, not like a wrestling mat, it's its own thing, and when I am there, I am floating, I am moving with total freedom, I am free. And when you know, when you just know you are going to win, like I do, there is no better feeling.

I don't use machines - animals don't use machines.

I studied every move, I became fascinated by thinking what I could have done differently. And I take that approach now as a professional. I am on it, all the time, never stop thinking, learning. You don't get to be world champion unless you do that.

Doubt is only removed by action. If you're not working then that's where doubt comes in.

I'm not a fan of routine.

I do yoga. People think it is easy, just touching your toes. It is hard. But I tend to go with my own flow. It's back to the movement thing. I feel it when I need to train, and I do what I feel I need to do. And when I am in the run-up to a fight, I am really at it the whole time, might be getting my weight down to meet the limit for the division. Soon I am moving up and I am going to be champion in the next one too.
