London: British comedian Russell Brand lived with a squad of American marines to toughen up.

The comedian, who recently took up kick-boxing in an attempt to get fit for his wedding to singer Katy Perry, bunkered down with a group of tough military men for a weekend but struggled to keep up with them, Female First reported.

Speaking to US TV talk show host David Letterman, Brand said, "I love the marines. I respect them and can`t believe what heroic deeds they do and the way they live. I went to live with them for 48 hours to see what it would be like," said Brand about the experience.

"They woke me up at 3.30 in the morning to go on a 10km hike, with 70lbs of luggage in a big backpack. A lot of the stuff in it, you didn`t even need! Three sleeping bags, there`s only one of me," he added.

Meanwhile his fiance has also been preparing for the big day, by cutting back on her favourite foods.

The`I Kissed A Girl` singer recently spoke about how she has had to stop indulging in many of the waist-expanding delicacies she loves, which include Chinese food and pizza, because they are fattening.
