Jane Fonda releases keep-fit DVDs

London: Actress Jane Fonda has released two `Prime Time` low-impact workout DVDs for older fans.

The trim Hollywood legend, 72, shows her secret is a bit of OA-PE - in her keep-fit video.

They are her first fitness films in 15 years.

"I know from experience how critical it is for seniors to be physically active," the Sun quoted, star of 1968 movie Barbarella, as saying.
