Flirty Girl Fitness™ is the brainchild of sisters Kerry and Krista Knee, who quickly became known as "The Flirty Girls". Kerry and Krista were born in Newfoundland, Canada but spent most of their upbringing in Halifax, Nova Scotia before moving to Toronto, where they started Flirty Girl Fitness™.

Kerry & Krista’s move into fitness began in 2005 after Kerry, who has always been into personal fitness, became interested in pole dancing, but she couldn’t find any classes available. Seeing the opportunity for a sexy new workout, she bought a pole to teach herself. When Krista came to visit her sister, they were both amazed how quickly she took to this new sport; within weeks, Krista was mastering the spins and techniques involved in pole dancing. With the sister’s business experience, and newly discovered prowess on the pole, this dynamic duo developed and launched Flirty Girl Fitness™.

The original Flirty Girl Fitness™ is now one of the top fitness facilities for women in Toronto since opening in December 2005. Wanting to expand and break into the American market, Kerry & Krista opened their second location in Chicago in 2007. This fabulous flagship studio boasts 3 dance studios, a full service spa and a gorgeous sunning patio for its members.

Anxious to share their program with women everywhere, the sisters partnered with Savvier Fitness to develop the Flirty Girl Fitness™ Home Edition, a collection of dance and fitness DVD’s designed for use in the home - it has since become a national phenomenon! Now, Savvier Fitness and the sister’s are bringing the program to fitness facilities across North America with the Flirty Girl Fitness™ Flirtification program. This instructor training program certifies fitness professionals to teach Flirty Girl’s most popular class, Booty Beat.
