Arnold Schwarzenegger has revealed he still does his own stunts - but sometimes needs an afternoon nap in between shooting.

The action hero admitted the stresses of daily life sometimes take their toll on him, telling the Daily Mirror: "I sometimes take a nap in the afternoon.

"I sometimes take them when I feel sleepy and I am at home, then I have the luxury of lying down for an hour."

The 66-year-old never indulges in a nap when he's filming.

"You get an hour lunch break and then you work until seven at night, so there's not like, 'OK guys, why don't you continue, I am going to take a little nap'. There's no time for that."

Arnie, who next stars in David Ayer's action thriller Sabotage, revealed his physique also takes more time to bounce back now that he's older.

"I still get picked up and thrashed around and that's just the way it is, and if you don't like that, then you are in the wrong business. The advantage is to be in shape, you can do all of those things and you do feel the same way you did 20 years ago. But the body does not recuperate the same, as fast," he said.

"It's like if you do something unusual and you are tired, the next day your body doesn't come back as quickly as when you were 30 years old. But, other than that, I can still do the running, the jumping and the fight scenes."

And while he has no doubts about doing the stunts, he was upset about the request to dye his hair grey in the film.

"I wore a hat all the time I was off set because people would say, 'Jesus, you look weird'," he said.
