Nowadays, playing a superhero on the big screen is no picnic. To accurately bring these powerful, god-like beings to life, actors must undergo intense physical training to look like they were lifted straight from the comic book page. Every Marvel Cinematic Universe actor had to go through this process, from Chris Hemsworth and Chris Pratt to Paul Rudd. And it's no different for Brise Larson.

In the latest behind-the-scenes video of the upcoming Captain Marvel, the actress briefly takes us through the intense training she went through in order to bring Carol Danvers to life in Marvel Studios' highly-anticipated film.

"I've been training for nine months," Larson says in the video, mentioning that some of these months even included double the amount of physical work. "Three months of two-a-days, four and a half hours a day." The video shows plenty of Larson's various exercises, from weighted lunges, boxing, sledgehammer slams and weighted push-ups to hip thrusts, medicine ball sit-ups, leg raises and fight training.

Larson explains that she is "trying to be as prepared as possible. This requires a crazy amount of discipline and physical strength. I don't think I fully understood the scope of it, and to feel this connection to my body in a way that I hadn't before, it's incredible. It's like a triathlon to be part of these legendary superheroes."

This isn't the first hint we've had of Larson's grueling training sessions. A few weeks ago, the actress released a video in which she can be seen pushing a 5000-lbs jeep up a road. "Her dedication is extraordinary," adds co-star and fellow sparring partner, Jude Law.

Captain Marvel will be Marvel Studios' first female-led film, a role that Larson is taking extremely seriously both on and off the screen. In fact, the actress recently used her position to demand a more diverse crop of journalists to cover press junket for the film, earning praise on social media.
