Chris Hemsworth, 37, has been bulking up to play the WWE legend Hulk Hogan in an upcoming Netflix biopic and it shows! The actor posted a shirtless pic of himself showing off his incredible muscles on the tiny Australian island of Lord Howe in an Instagram post on Jan. 19. He was joined by his wife Elsa Pataky, 44, who was also showing off her fantastic figure in a bikini, and what appeared to be two of their three kids, as they stood on a large rock near the water.
