Jill Dailey McIntosh has always been intrigued by the human body and how it moves—so much so that she graduated in 1991 with a kinesiology degree and soon thereafter decided to open her own Pilates training studio. One question she always asks herself is: "How can one aggressively transform the shape of their body while still maintaining proper alignment of the spine?" Eventually Jill began to examine her diverse fitness background, pulling low-impact movements from ballet, Pilates, and even orthopedic-exercise routines to create the basis for her fitness style, The Dailey Method. Which she opened in the Marina district of San Francisco.

Now, nearly two decades later, Dailey's fitness routine has ballooned into studios sprawled across more than 10 states and gained praise from Self, Allure, FitPregnancy, and InStyle magazines. Regardless of the location, instructors remain true to Jill's mission of offering a diverse series of exercises that focus on toning and lengthening the body while lengthening the spine and building strong core muscles.
