In February, the Room actress opened up to Insider about her fitness journey and preparing for her role in Captain Marvel.

"So, I started this journey thinking I'll get strong and I had no idea. I went far beyond what I ever believed was possible for my body," she explained.

"Being able to hip thrust 400 pounds, deadlift 200 pounds, push my trainer's Jeep, I mean, it's an incredible experience to realize what's inside of you is well beyond what you knew was possible," she added.

Larson was not always a fan of the gym before joining the Marvel Universe.

"I affectionately called myself 'an introvert with asthma' before I got to play Carol Danvers and I started training first out of sheer panic," she said.

"That's part of why it's no surprise to me that this character has been able to reverberate outward, because she first and foremost changed my life," she added. "So it makes sense to me that she could change other lives too."
