Mark Sisson is a former elite endurance athlete who has made health and fitness his life’s work. He realized that his calling was as an independent researcher, critical thinker, motivator, and communicator -- to get people to take responsibility for their health and fitness (often in the face of flawed conventional wisdom that can lead even the best-intentioned astray), and to inspire people to be open-minded, passionate, and enthusiastic about leading a healthy, happy, fit, balanced, active lifestyle, with the least amount of pain, suffering and sacrifice possible.
