"do a few Jane Fondas"

Jane Fonda is an American actress, writer, political activist, former fashion model and fitness guru. After fracturing her foot whilst filming The China Syndrome she began aerobics and strengthening exercises under the direction of Leni Cazden.  She released a video called Jane Fonda's Workout, which sold 17 million copies - more than any other home video - and was the reason that many people bought a VCR.  She went on to make 23 exercise videos between 1982 and 1995.
