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 teaching studio. But it wasn't until years later that this curiosity would manifest itself in a single question: "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.

Now, more than a decade later, Dailey's fitness routine has ballooned into hardwood-floored studios with on-site shower facilities sprawled across more than 10 states and gained praise from Self and Allure 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.
