London: Gerard Butler says he is doing yoga along with other exercises to lose weight.
"(I am) watching what I eat. I stopped lifting big weights and I`m doing yoga," femalefirst.co.uk quoted the 41-year-old as saying.
Butler also says that he was maintaining a slim figure because he was doing a surfing movie.
"If I wear a long shirt, everyone says, `Oh my, God! He lost so much weight!` But this is just how I look. I just used to be a lot bigger. But now I`m surfing. I`m doing a surf movie so I have to slim down."
