Actor Liam Hemsworth says he indulged himself in a workout session to prepare for his shirtless scene in The Dressmaker.

The 26-year-old actor, plays Kate Winslet’s love interest in the upcoming movie, reported E! online.

"I didn’t eat for weeks," Hemsworth jokingly said.

The Australian actor, however, did do a mini-workout before shooting his shirtless scenes.

"I did some push-ups in my trailer. Anytime you’re going to come out and take your top off, it’s good to do a couple of push-ups. It’s very difficult to come out and just take your clothes off." 

Hemsworth says after he wrapped up the filming he celebrated with burgers and fries.

"I think I ate a lot of chips after that day. As soon as you get your shirt off scene done you’re like, all right, let’s head to McDonald’s or wherever. I don’t actually eat McDonald’s, but somewhere with burgers and fries!"
