These GOT Stars Are So Fit, They All Deserve a Seat on the Iron Throne

To prepare for her role as Jean Grey in X-Men, Sophie transformed her diet and exercise routine, which she told Self in 2016 wasn't a regular routine to begin with. Working with celebrity trainer James Farmer, her fitness schedule consisted of workouts like hill sprints, kettlebells, and boxing, and she followed a "low-carb, Paleo-style" eating plan. Sophie worked out for at least an hour six times per week at the time, and she recently told Vogue that she still likes to box.

Kit is not active on social media (you know nothing Jon Snow), and even though we can't see what he's up to fitness-wise, he's given plenty of interviews about his workout routines in the past. Men's Health UK recently reported on his training schedule throughout his roles, especially in Pompeii and GOT. Kit revealed that he was "eating all the time: loads of good carbs, like brown rice and sweet potatoes," and his workouts consisted of full-body sessions featuring strength moves like barbell deadlifts and pull-ups.

In case you couldn't already tell from his role as The Mountain, Hafþór is an incredible powerlifter. He currently holds the title of World's Strongest Man, and has championed countless other competitions (multiple times), including Iceland's Strongest Man and Europe's Strongest Man.

Nikolaj told Men's Health UK that to bulk up for movies, he eats a lot of protein, and that he feels "stronger now than I ever have." Nikolaj put on 20 pounds of muscle for his 2017 film Shot Caller.

Nathalie's trainer recently spoke to Prevention about her workout routine which, spoiler alert, is no joke. She goes to the gym six times a week and does different sessions of boxing, strength training, yoga (she's a major yogi), and cardio circuits. View the full workout plan here.

I mean, let's be real: we all know Jason Momoa has muscles for days (have you seen Aquaman?!). Here are 23 shirtless pictures to prove it. He's into boxing, surfing, and climbing, and he told Men's Health, "When I have to change my body type [for a movie], then we just switch it up. Doing a lot more weights for size; a lot more cardio for definition."
