He's packed plenty of muscle in films like "Thor", but this time Chris Hemsworth has really gone in the opposite direction.
As someone who worked with Chris in Home & Away for 5 episodes (and got changed in the same room many times whilst having character impersonation competitions, sorry ladies!) I can tell you first hand his physique is incredible.
However, not every film calls for gains, and this particular role is the one of first officer Owen Chase in Ron Howard's new film "In The Heart Of The Sea."
In The Heart Of The Sea Diet
Hemsworth says he was on 500 calories a day at times to reach the super low levels of body fat.
The film is based on an 1820 event whereby a whaling ship is stalked and terrorised by a large whale.
The whale causes the crew and the ship to be stranded for 90 days, thousands of miles from home.
So naturally, protein intake was low and there were most likely no dumbbells on board.
So what would you like if that happened? I think Hemsworth has nailed it!
Chris posted the photograph with the caption: "Just tried a new diet/training program called 'Lost At Sea.' Wouldn’t recommend it… #IntheHeartoftheSea.”
I'm sure he'll have the size back in no time!
Check out the trailer for the film below:
"Stay Fit, Stay Flexed!"
Chris Hemsworth had to suffer to lose the weight to play this role - but the good news is, you don't have to!
