I actually don't prepare for onscreen nudity. I really believe that you have to be comfortable with your own body and unless the role is directed to a certain physicality and you're playing a sports person, then obviously you've got to train for it, but I just try and do things that make me happy and comfortable in my own skin, so I've gotten into yoga quite a lot.
