"We did two hours a day, and it was brutal. I usually like working out. Going in sucks, but walking out, you're like, 'I'm glad I did that!'" the 30-year-old actor told PopSugar. "This was different. I'd walk out and I'd be like, 'I need to vomit. I hate this trainer. I hate this movie. I want to go to sleep for a week.' It was just relentless. I've got a fast metabolism and I lose weight very quickly, so for me to get big, it was just eat a lot."
In the new film (which hits theaters July 22), Evans plays Steve Rogers, a puny military reject who undergoes an experiment that transforms him into the very buff and muscular Captain America.
But being forced to put on weight isn't as fun as it sounds for Evans.
"Working out sucked, eating sucked more," he revealed. "You get to a point where you just can't even look at another piece of chicken. You're just so bloated, but you just have to keep consuming protein, so that was tricky."
As for shedding the weight to play Captain America's alter-ego, director Joe Johnson didn't put the pressure on Evans to lose the mass he worked so hard to pack on. Instead, special effects were used to turn him back into a smaller version of himself.
"They went back and forth on the type of technology they were going to use. Initially, they were just going to do body shrinking, and then they thought, 'Well, maybe we can get another skinny actor and put Chris' head on it,' and I really, really was against that," Evans told USA Weekend. "I said to Joe, 'Look, I know we want this to look good and this effect to not be distracting from the film, but it has to be my performance. I don't want to share this. Your body is a huge piece of the acting puzzle, and I don't want to have somebody else's body tell the story that I'm trying to tell.' So they did some tweaking and they did a bunch of tests and we went back to the initial plan to shrink my body."
Previously a team player in The Fantastic Four, Evans says the pressure of being the main star of a flick almost kept him from accepting the coveted role.
"I said to someone close to me, 'I was offered this movie and I think I’m going to say no.' And she said, 'No, you’re not. You’re going to do this movie.' I said, 'Why?' And she said, 'Because you can’t live your life based on fear.' That’s a really good point: I think I’d end up having more regret if I didn’t do it because I was scared than if I did it, and whatever comes, comes. At least I wasn’t a coward."
