Sam Worthington - Gym-Hater Sam Worthington

Sam Worthington doesn't see the point of going to the gym.

The 'Avatar' actor - whose impressive physique earned him millions of admirers in James Cameron's 3-D blockbuster - admits he isn't a huge fan of exercise and can't see why anybody would want to work out for hours.

He said: "I didn't do anything to buff up - nothing. I'm not one of these yoga-loving, I-only-want-wheatgrass-and-blueberry-muffins kind of guys. And I don't go the gym; I think it's pointless. If I'm going to pick up something heavy, I'd rather take it somewhere."

The 33-year-old heartthrob - who is dating stylist Natalie Marks - also says he's not concerned about the clothes a woman wears, just that they have a good smile.

He told Britain's Cosmopolitan magazine: "I go for a nice smile when it comes to women because that means she finds me funny, and a smile lightens the air. A girl can wear the worst clothes, but she'll still look good if she smiles."

He also insists he's not fussing when it comes to his own outfits, saying: "I've had these Australian black Blundstone boots, which are falling apart, since I was 20. What do I need 20 pairs of shoes for?"
