Brie Larson is pumped up

She’s ripped for “Captain Marvel.”

Brie Larson may not quite be able to shoot beams of energy out of her fists, but as for the other physical requirements of starring in the comic-book movie “Captain Marvel”? Let’s just say, don’t mess with her.

Larson, a first-time action star but longtime serious actor, trained for nine months to get fit to play superhuman Carol Danvers, aka Captain Marvel.

“I just assumed everybody did their own stunts, but it turns out they don’t,” Larson told USA TODAY on the “Captain Marvel” set. “It was happy ignorance, I guess.”

Happy ignorance was required – along with, for several weeks, two-aday workouts.

“It would be a half-hour in the morning of stretching and stuff on my own. Then I’d go with my trainer for an hour and a half. Then I’d go home, shove a bunch of food in my face, take a shower, take a nap under infrared light, wake up an hour later, put on another set of exercise clothes, and then go to the stunt gym and work with the stunt team,” Larson says.

By the time Larson was shooting the film, which involves plenty of combat scenes and punch-throwing, she was able to deadlift 225 pounds, do 10 pullups in a row and hip-thrust 400 pounds, which “was something I never thought I could do,” she says.

“Captain Marvel” producer Jonathan Schwartz, who also produced the “Guardians of the Galaxy” movies, calls Larson the “next Tom Cruise.”

“On any other Marvel movie, stunt doubles would be doing 99 percent of what she’s doing,” he said. She spent so much time at the stunt gym, “We sort of had to say, ‘You need to get some rest. Stop pushing yourself so hard.’

“But when you see this movie, the amount of practical stunts that she’s doing by herself will boggle your mind, and make you say, ‘I can’t believe they let her do that.’ ”

While in intense workout mode, Larson sent clips of her preposterously difficult workouts to co-star Samuel L.

Jackson.

“She had one video where she was powerlifting like 250 pounds. She sent another video of her pushing a Jeep up a hill,” Jackson says.

“Yeah, she’s pretty ripped.”
