"The core-strengthening along with the hip-mobility exercises will help make your body more efficient. I sent a copy of this workout to Kathrine Switzer, who is the first woman to officially run in the Boston Marathon (in 1967). She wrote me a lovely letter in which she said 'I listened and did the routine - TREMENDOUS! I loved it. Your workout is helping me a lot. Thank you.'

"The Personalizing Pilates: Runners workout program includes three files. First is the free Ab Tutorial, which is a short workout that teaches you how to find and engage your deepest, supportive abdominal muscles. These muscles are important because they support the spine while your legs move and flatten the tummy!

"In the workout, my voice guides you through a Pilates workout that focuses on strengthening your abdominals, mobilizing your hips, and stretching out tight leg muscles."
