Superstar George Clooney has been hitting the gym regularly to stay fit.
The 52-year-old actor said he works hard to stay in shape and stop himself from getting injured on set, reported Daily Express.
"I train every day because, at 52, I worry that if I don't something will fall off! It's not something you think so much about when you are younger - but when you do a movie that requires you hanging from wire for hours on end and acting as if you are weightless, you're kind of glad you did all those push-ups and sit-ups," he said.
Clooney is all geared up for his 3D techno-thriller "Gravity", which stars Sandra Bullock opposite him. The Alfonso Cuaron film is expected to hit theatres on October 4.
