Washington, Jan 26 : Hollywood star Jon Voight has revealed that he keeps himself fit by running backwards.

The father of actress Angelina Jolie hits the canyons and streets near his Los Angeles home twice a week for a stress-free jog.

He thinks that reverse running helps clear his head.

"As you get older, you have to do something to keep yourself fit. You have to watch what you eat and I have a little regimen I do that I don''t tell anybody about," Contactmusic quoted him, as saying.

"A couple times a week I go running and I run backwards. I run up hills," he added. (ANI)
