When Brie Larson landed the starring role as Captain Marvel, she knew she had to get stronger. To do so, she turned to trainer Jason Walsh, who boasts a long track record of helping celebrities build super hero physiques.
Starting off, Larson had almost no prior experience with training. But she made quick progress under Walsh's program.
"You're told women aren't supposed to have a lot of upper-body strength. That's bull****. They get really, really, really strong pound-for-pound," Walsh told Vanity Fair. "For Brie, I think we ended up doing eight Pull-Ups straight." Other impressive feats included eight Push-Ups with a 50-pound chain draped across her back and hip thrusting well over 300 pounds.
"I didn't know what strength was. I was truly an introvert with asthma before this film, so I had a lot of work to do, and I just started to fall in love with it. I started to fall in love with the way my body was changing and transforming," Larson told E! News.
"If I was seeing this movie, I think it would mean so much more to me knowing there was that type of dedication put into it and that it's not, 'Girls are strong with CGI…It's, 'Girls are strong [period]!'"
