Playboy.com: What was going through your head that you wanted to keep fighting with the broken arm?

Sylvia: I was pissed off. I knew I could beat Frank Mir. I slammed him hard. And then, when he broke my arm, I picked him up and dropped him on his head, and he went limp. I was getting ready to pick him up again, and dropping big lefts on his head and face, but the referee stopped it. He's got a weak chin. All I had to do was hit him once, and he was gonna go to sleep, too.

Playboy.com: Who's tougher, heavyweight boxers or heavyweight UFC fighters?

Sylvia: Heavyweight UFC fighters, for sure. They train six weeks for a fight, that's it. We train full-time, all the time. I put in today three hours already. I'm putting in another three tonight. I've done three different workouts already. Tonight I've got to do boxing for a half hour, grappling for an hour and strength and conditioning for 45 minutes.

Playboy.com: What's the most intense part of your workout?

Sylvia: My toughest workout is the hour of grappling. I've got four guys coming after me who are fresh, rotating in on me, and I'm going an hour straight. They're pushing the pace, and I gotta keep up on them.

Playboy.com: Is that tougher than the actual fight?

Sylvia: There's nothing I'm not ready for. When I train hard and I have guys pushing me, the fight's the easy part. The training's the hardest part.

Playboy.com: What kind of purses do UFC fighters commonly win?

Sylvia: I don't get into money. The heavyweights are up there, over $100,000. But it's a private thing, talking about money.

Playboy.com: Do you think one day, UFC purses will reach the millions boxers make for fights?

Sylvia: I hope it gets there someday. We work harder than they do, we're better athletes than they are, we're putting more asses in the seats, we're selling out venues, we have more pay-per-view buys. We're taking over boxing, it's inevitable. So we should be getting the pay that the boxers are getting as well.

Playboy.com: When asked whether he thinks it's inevitable that someone will get killed or seriously injured in a UFC fight, Dana White recently told Playboy magazine, "I fear it. I really do." Do you fear that you -- or someone else -- might get killed in the ring?

Sylvia: I don't fear, myself. I think it's a relatively safe sport. It's nothing like boxing. You don't take hundreds of punches to the head each round, unless you've got two really good stand-up guys. There are just so many ways to end the fight. With the small gloves that we wear, it only takes that one punch. There are a lot more knockouts in the UFC because of the small gloves and the heavy punchers in the heavyweight division. I don't think it's going to happen, not in the UFC. It could happen in a little rinky-dink show, possibly, because they're not regulated as well, and they don't have all the physicals that we do. Every year we have MRIs, CAT scans, blood work, physicals. Nevada and California are pretty strict on those types of things.
