Here's some good news and some bad news: Chris Evans looks good in Captain America: Civil War. Like, gooooooood. So good, in fact, that he ended up injuring himself.
"You try and get as fit as you can by the time you start, and then throughout the filming, you just gradually lose weight, because in that suit every day, you're sweating nonstop, you're tired, your workouts kind of fall off a little bit," the 34-year-old actor tells ET's Carly Steel of the secret to looking super buff on the big screen.
"So, they load all the scenes where you have to be in a T-shirt in the beginning of the movie," he reveals.

One scene in particular -- which can be glimpsed in the trailer -- finds Evans' Steve Rogers trying to stop a helicopter from taking off. He's wearing one of those aforementioned T-shirts and his biceps are on point.
"That was in the first week of filming. And I actually messed up my arm doing it, I really did," Evans says. "It's a fake helicopter, obviously, but it was drifting beyond the ability of control. I tweaked a little something. To this day, I'm still messed up."
Cap is all suited up though in the newest clip from the Marvel epic, which debuted during the MTV Movie Awards on Sunday. In the action-packed snippet, we see the super soldier get an assist from Falcon (Anthony Mackie) and Scarlet Witch (Elizabeth Olsen) to take down some baddies.

Lest you think all our talk of Captain America's muscles is gratuitous, Evans recently admitted that he is an "a** man" on Anna Faris' podcast. "I'm way, way, way more of an a** man, clearly more of an a** man," he candidly revealed on the show. "Just everyone knows. I like butts."
"You gotta understand, we're doing a podcast in Anna's living room," he now tells ET. "We're just hanging out. You're just talking. And you're talking for like three hours, and you just start talking normally. Then, of course, you guys just know how to cherry pick those lines and blast them onto headlines, don't you?"
But Evans says any momentary embarrassment won't stop him from speaking his mind, adorably adding, "I'll keep jamming my foot in my mouth as long as I can. Don't you worry."
