In the movie “Captain America: The First Avenger,” Steve Rogers makes it look easy to get big and buff — all it takes is a bit of super-soldier serum. For actor Chris Evans, however, the process was a little more complicated.

MTV News spoke to Evans as part of our Summer Movie Preview Week, and the actor was the first to admit he didn’t enjoy his "Captain America" workout regimen and diet at all.

“Oh my god, when shooting was done I just stopped going to the gym completely for about three months,” he told MTV News.

Then there was the issue of food, because as Evans revealed, “I didn’t really have to diet.”

“I’m pretty skinny naturally," he said. "So for the most part, when I try to get big, I have to eat everything. And that’s tough, oddly enough, when you just don’t want to eat food, you’re just full, but you have to eat another piece of chicken, you have to. It’s the worst.”

That sounds similar to the laments of “Thor” star Chris Hemsworth about eating to bulk up for a superhero role.

“The workouts were exhausting,” Evans continued. "It’s the workouts that, you know, make you want to vomit. It’s horrible. You try to think of any way to get out of it before you go. And you’re just so glad when you’re done.”

Once he was allowed to stop the heavy workouts and binging, he happily did so.

“I threw in the towel in December,” he admitted.
