A photo of Hafþór Júlíus Björnsson - aka The Mountain - as a teenager has highlighted just how much he's transformed his body.
The Game of Thrones star was playing basketball for K.R. Basket Reykjavík in his native Iceland back in 2006, when he was 17-years-old.
Clearly, he was a big boy back then, but you wouldn't have known that he would go on to become the world's strongest man.
Transforming himself into the man mountain that he is today has taken countless hours of gym work and training; although in 2019, he admitted that he has used steroids too.
Björnsson made the confession whilst talking to ESPN for the show E:60. When asked if he'd ever used steroids, he said: "Yes, I have."
He continued: "When you want to be the best, you do whatever it takes."
During the rest of the interview, he elaborated on how he went from scrawny teen to actor and strongman.
He said: "My dream was always to become a professional basketball player but that dream didn't go too far.
"I broke my ankle twice. I had to have bad surgeries that ended my career.
"In 2013 the Game of Thrones crew were filming in Iceland and they heard about this massive, muscular, handsome, big young guy.
"At first I got an email. I didn't have any acting experience and getting an email like that out of nowhere from Game of Thrones was like, 'Nah, that's not true, it's got to be bulls**t.'
"So I didn't answer the email. A few days later I got a phone call and it was a man who asked if I wanted to audition for Game of Thrones. I obviously said, 'Yes. I don't know what I'm doing but yeah, let's try it'."
He continued: "They asked me to pick one guy up, to see if I was strong enough. I picked the man up over my head easily. They were very surprised: 'Woah, OK you're strong'."
