Here's how 'Daredevil' star Charlie Cox got ripped to be a superhero

Charlie Cox had to seriously step up his game to play the title role in Marvel's first Netflix series, "Daredevil."

"The truth is, before I did this show, I'd never really been in shape, I never really had a gym membership, and I'd always just occasionally go for a run, that kind of stuff," Cox told Business Insider.

On "Daredevil," which just released its second season, Cox has to perform extensive fight scenes, exhibit great flexibility, and just look all-around awesome in the superhero suit. For a guy who wasn't a gym rat to begin with, it takes commitment to keep his fitness level high.

"It was such hard work to get into shape, that when we finished the first season, just on the off-chance that we were going to do it again, I didn't let myself completely go," Cox said. "I just couldn't bear the idea of having to start over again."

"He's committed. He's the real deal," Cox's personal trainer and the creator and president of Arazi Fitness, Naqam Washington, told us.

Regarding his training style, Washington said, "Nowadays, people train to get optimal movement from their body. They train like an athlete. And I have an MBA and MMA background, so it works well with Charlie. We did modern, sport-specific, MMA movement."
