The actor beefed up for the role of Thor in the movie of the same name. For the film's subsequent sequels he maintained the physique, reported Contactmusic.
"Thor is large. For that I had to add some muscle, which hasn't been all that hard so far. I like training just fine, thanks. But to play a Formula 1 driver, I had to drop quite a bit of that. You know, slim it down.
While Hemsworth is a fan of racing, he admitted he prefers motorbikes to cars.
"I grew up in a culture of motorbike. So I like racing just fine. Quite a lot, actually. That was when I was a boy in Australia. And I never really made the jump to cars after that.
