Fitness expert Mari Winsor is widely credited with popularizing Pilates and making this once-obscure workout accessible to the public at-large.

In 1990, Mari opened her first Pilates studio in Los Angeles, and introduced her innovative signature workout, "dynamic sequencing," based on techniques developed by Joseph Pilates. Soon after, the highly visible bodies of musicians, professional athletes, and celebrities began to flock to her studio to be shaped, toned, and strengthened.

Eager to learn as much as she possible could about Pilates, in 1992, Mari began studying with Romana Kryzanowska, who trained with Joseph Pilates and took over his New York studio upon his death. After one year of intense study, Mari earned her certification in the true technique of Joseph Pilates. Mari continues to study with Romana to this day.

In 2003, Mari brought Pilates to a new level of public recognition when she released her first infomercial. The record-breaking success of the Winsor Pilates workout series and award-winning infomercials was unparalleled. Thirty videos later and over 50 million programs sold, Mari's groundbreaking dynamic workouts have helped millions of Americans get the body they want making Winsor Pilates a household name.

Committed to sharing her knowledge and experience with the public, Mari has created an Online Winsor Pilates Fitness Club. She has co-authored three books: The Pilates Powerhouse; The Pilates Pregnancy: Maintaining Strength, Flexibility and Your Figure; and The Pilates Workout Journal: An Exercise Diary and Conditioning Guide. Mari's fitness expertise has been featured in countless magazines such as: Allure, Glamour, Fit Pregnancy, Health, InStyle, More, Redbook, Shape, Vogue, W, and Woman's World.

Now the owner of two Winsor Pilates studios and with a continuous roster of A-list clients that includes Drew Barrymore, Elizabeth Berkeley, Minnie Driver, Daisy Fuentes, Jasmine Guy, Jewel, Melanie Griffith, Meg Ryan, Sharon Stone, Marisa Tomei, Courtney Thorne-Smith and Dita Von Tees, Mari remains the most sought-after trainer in Hollywood and a celebrity in the world of health and fitness.
