Chris Hemsworth's 'exhausting' "Thor" weight

November 30th, 2014

Chris Hemsworth finds it ''exhausting'' carrying extra weight when he plays Thor.

The 31-year-old star - who was recently named PEOPLE magazine's Sexiest Man Alive - admits he usually goes on a diet after playing the 'Avengers Assemble' character because none of his clothes fit.

He said: ''When I'm not doing that character, I want to get lean again as quickly as possible, because carrying that weight is exhausting. And none of my clothes fit.''

The Australian actor relies on a combination of weight lifting and bodybuilding to get him in shape for the role, but admits he doesn't pile on the pounds that easily.

He said: ''I'm lucky. Genetically I don't put on weight easily. I like running, surfing or boxing, and I did Muay Thai for a long time. If I have a goal, I'm really good about what I eat - protein, veggies, clean food and restricted carbohydrates. Cheat days are pizza, hamburgers, beer, sugary things. Everything I'm not allowed to have!''

Chris also enjoys getting massages to help him relax after a long workout.

He said: ''I love massages - hard Thai ones. I hate falling asleep during them. I want to know something is happening.''

Despite putting a lot of work into his physique, Chris insists he is very low maintenance when it comes to grooming.

He added to PEOPLE magazine: ''I'm sick of my hair. I have a hat on most of the time just so I don't have to deal with it. I don't like being clean-shaven, because my skin feels likes it's going to break out in a rash, so I clipper it nice and short.''
