'I couldn't breathe': Gal Gadot admits her Wonder Woman costume was too tight...until she started regular workout routine

She said: 'I couldn't breathe when I first tried the costume on, it was so tight. So I went to the gym, tried it on again and it felt great, a much better fitting.'

However, her plan didn't quite work as the costume department then decided to make it tighter. 

She did eventually convince them that she would need it a little roomier whilst shooting the film.

She added: 'So they made it tighter. I made it very clear that I needed to have some oxygen going through my body to shoot the movie.' 

'We adjusted the costume and I wore it every single day, and we shot over 117 days. The new version was great. I can even sleep in it. It’s like pyjamas.'

And the Batman v Superman: Dawn of Justice star admits it was tough training for the role.

The star told the newspaper: 'I am quite sporty but this is another level.'

She added:  'I couldn’t even do one pull-up when I started. So if I can do it....' 

Wonder Woman arrives in theaters June 2, 2017.

The action film also stars Robin Wright, Chris Pine, and  David Thewlis.
