Jane Fonda's Workout, also known as Workout Starring Jane Fonda, is a 1982 exercise video by actress Jane Fonda, based on an exercise routine developed by Leni Cazden and refined by Cazden and Fonda at Workout, their exercise studio in Beverly Hills. The video release by Karl Home Video and RCA Video Productions was aimed primarily at women as a way to exercise at home. The video was part of a series of exercise products: Jane Fonda's Workout Book was released in November 1981, and both Jane Fonda's Workout videotape and Jane Fonda's Workout Record, published as a double-LP vinyl album, appeared in late April 1982. In July 1982, Fonda's exercise video was released on RCA SelectaVision videodisc. The VHS tape became a bestseller, and Fonda released further videos throughout the 1980s and into 1995. The video also increased the sales of video playback units.
