Hi, Marvel fans! I'm Krista and sometimes I like to pretend I'm Daenerys Targaryen. View this photo on Instagram instagram.com Oh, and that's not really Jason Momoa, that's my co-worker Christopher Hudspeth who wishes he was him. But this time, I've decided to switch things up a bit. It's time for me to be Captain Marvel. Marvel / BuzzFeed To physically prepare for the role of Captain Marvel, Brie Larson worked with celebrity trainer Jason Walsh. View this photo on Instagram instagram.com Jason has worked with celebs like John Krasinski, Jessica Biel, Mandy Moore, Alison Brie, Chloë Grace Moretz, and many more. So, I met with Jason at his gym, Rise Movement, to go through the exercises he did with Brie. BuzzFeed Normally, the only workouts I do are running or cycling, so the reps he had me do definitely left me winded.

He said I could use the app as a guide on my own (it was very helpful). Playbook It is a free, two-week program where Jason walks you through each workout with step-by-step videos. So, following the app, I decided to do the workouts for two weeks. Some of them could actually be done at home, like this resistance band exercise. BuzzFeed Don't let the above pic fool you, it was taken after only the first rep. I was intensely sweating by the end of it. There were three workouts per week, and each workout was an intense 45 minutes. Here is an unflattering pic of how sweaty I was at the gym: BuzzFeed As someone who only does cardio as a workout, this regime was very challenging for me. I was sore in new parts of my body. At the end of each workout, I felt stronger than the previous one. And after two weeks of doing the exercises, I felt like SpongeBob in this GIF: Tap to play or pause GIF Tap to play or pause GIF Tap to play or pause GIF Tap to play or pause GIF Nickelodeon In conclusion, I think if someone were to do these workout for an extended period of time, they would definitely be stronger with visible muscle definition. I feel like going forward I am going to incorporate these new workouts into my routine. I have so much admiration for Brie, who clearly SLAYED the part of Captain Marvel!
