Gemma Arterton keeps fit via Skype.
The 27-year-old actress underwent exercise routines with a personal trainer over the internet video communications software six days a week while shooting forthcoming film 'Byzantium' because she can't bear to set foot inside a gym.
She said: ''It's the new thing, we've decided, because I was filming in Ireland. I hate working out in gyms, and I don't like the way they make your body look.''
While Gemma was keen to get in shape for the movie - in which she plays Clara, a vampire prostitute and mother who is protective of her daughter, played by Saoirse Ronan - she insists too many ''intelligent actresses'' are slimming down in excess.
She added to Marie Claire magazine: ''I saw an actress I know and she's lost so much weight. She's gone from a size 12 to a size four within two months.
''There are so many good, intelligent actresses doing this, and I just think, 'Why does that go hand in hand with the acting profession?' It shouldn't. It lets the side down. It lets down team woman.''
