He takes his love of the sciences and his knowledge of the human body and applies it to the basic training principles of endurance sports. He employs a "healthy skepticism" to many fads and products that say they will make you faster. He puts an emphasis on the individual, as no single program works for everyone. He understands each individual's personal makeup, including athletic background, skills, and health, along with full time job and family constraints. He is not only interested in making you faster, but making you healthier.
