When Sheila Kelley starred in and produced the film, Dancing at the Blue Iguana (2000), she prepared for the role of "Stormy" by learning how to striptease and pole dance. As a result, her body became long, lean and fit. She decided to take her knowledge of ballet, exercise and exotic dancing and combine them into a fitness dance workout for women called "S Factor"'. Kelley wrote "The S Factor: Strip Workouts for Every Woman" and has several "S Factor" exercise DVDs.

Her roles on L.A. Law (1986), Sisters (1991), ER (1994) and The Sopranos (1999) and in films including Singles (1992), Matchstick Men (2003), Nurse Betty (2000) and One Fine Day (1996) have earned her respect, as an actress who is not afraid of embracing the power of her femininity.

She is married to actor Richard Schiff, of The West Wing (1999), and has two children, Gus and Ruby. By: S Factor
