British actor Henry Cavil l has shown fans the gruelling fitness regime that turned him into a Superman.

The 30-year-old star is the star of new blockbuster Man Of Steel that took in a massive $128.7 million during its opening weekend making it the highest grossing movie in June.

In the online video, Henry stripped off his shirt to reveal his incredible muscles and is seen lifting huge weights and kettle-balls.

He pays tribute to his trainer Mark Twight for helping him get into tip-top condition for the movie that will make him a household name around the world.

He said: “Mark Twight is probably one of the most incredible people I’ve ever met.

“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.”

The training regime adopted by Cavill and Twight has been used to help a new recruitment drive for the National Guard in America,

Twight claimed that everything that the actor went through to get in shape was just as hard as any training a soldier would do calling it a ‘process of self discovery’.
