"Zero," he said.

Punk, who walked out on the WWE in January 2014 for myriad reasons and signed with UFC in December, also said that he doesn't watch any wrestling anymore.

"None," he said when asked how much he tunes in. "I don't watch wrestling anymore. I've tried to, but I have an aversion to it. You do something like that for however many years I did it, and it's like a lifetime. I've seen enough."

Punk did admit that he'll watch his wife, WWE Diva AJ Lee, when she's on and tells him she's excited about something.

"I will, yeah, I will watch her stuff," Punk said. "Chances are she'll only tell me to watch when she's excited about something. But, yeah, it's my wife, she's a grown-ass woman, she can do what she needs to."

While Punk distances himself from the product now, he said he holds no regrets about signing with the WWE in 2005.

"Well, yeah, of course," he said. "Like I said, I don't live my life with regrets. I don't even think there's really situations where I wish I would've handled myself a little bit differently. I wish I would've punched one or two people in the face. But, no, I wouldn't change a damn thing. Absolutely not."

Punk, who went on to become a five-time WWE World Heavyweight Champion, also said he enjoyed being under the tutelage of Paul Heyman during his legendary 434-day title reign.

"Working with Paul Heyman. That was the only thing that kept me sane," he said. "It was like a condition of, we get to work with each other because we don't like anybody else. So, working with him."

"The Best in the World" also spoke about the best parts of his tenure with the WWE.

"Turning chicken (expletive) into chicken salad. I think that's what the best workers always did," he said. "I think they took whatever idea they were given and they made it better. I think they take bad situations and bad ideas and make them palatable to the audience. I think they take bad material and shine it up and make it digestible. It was always a challenge because there's so much content with them. There's the three-hour Monday, there's the two-hour Friday and now there's NXT and there's Superstars and there's Main Event, and there's all these shows, and just trying to stay entertaining and trying to be riveting and trying to reinvent yourself every night, just staying over with the fans. That was always at least, for the most part, creatively stimulating."

Conversely, he also touched on the worst parts of his stint with the company.

"The worst part of it? After a while, I would say the worst part of it was their not listening and not understanding, and not getting a break when I probably needed one," he said. "Because who's to say where I'd be right now? They're always looking for the next guy, so nobody is really bigger than the company. Not that I ever thought I was, but I thought I was a pretty healthy cog in the machine. I thought I could've been afforded a vacation here or there."

Lastly, he touched on his UFC training as he will make his eventual debut likely sometime in late 2015.

"I definitely look at it as a full-time job. I'm here every day of the week," he said. "I take weekends off. But I'm here and I train with the pro team every day for two hours. Then some days I do two-a-days, so I'll come back. I live in Chicago, so I'm driving back and forth. Or some days I'm staying up here. So on those days, normally two days a week I come back and do extra, or even when I'm at home I'll do strength and conditioning, run. I'm very much all-in on this."
