To get in shape for this role, Hilary had to push her body to the breaking point. "The first time I heard [that boxing matches have a] three-minute round I thought, 'Three minutes? Wow, I'm really going to kick someone's butt. That's nothing.' And then I was halfway through and I almost threw up," she says.
Her workout and eating regimen was enough to put Rocky to shame. "I started training four and a half hours a day, six days a week," Hilary says. "In three months I ended up putting on 19 pounds of muscle. I had to eat every hour-and-a-half and I drank 55 to 60 egg whites a day."
So how was the workout? "It was all so great because it just put me in the mind set of a boxer.…I have to tell you, I felt so strong. I felt so confident. I loved it."
