A curious video has been making the rounds online – that of “Man of Steel” actor Henry Cavill working out in preparation for filming. And, well, if you thought he was perfect for the part before, you really need to watch this. The two-and-a-half minute clip shows the actor doing a work out that will have you renewing your gym membership in shame – or just reaching for the potato chips, as the case may be.

Sure, it’s not just due to Cavill’s abs that “Man of Steel” grossed an impressive $128.7 million at the box office during its opening weekend. But they didn’t hurt either. According to the video, released by the National Guard, the British actor hands over all credit for the grueling workout – as well as his tough mentality – to his trainer Mark Twight.

“Mark Twight is probably one of the most incredible people I’ve ever met,” Cavill says in the video. “He’s opened my eyes to seeing past what I thought were my limits. He’s a remarkable man, truly.

“He understands what I’m going through physically.

"He understands me because he sees what I’m going through as a person, which I think is what makes him such a good trainer.”

And this isn’t your standard Hollywood fad workout either. The regimen, developed by Twight has been adopted by the National Guard in America to train a new recruitment drive. Makes sense, after all, if it’s good enough for Superman, it should be good enough for the army too.
