Books by Mark Sisson

Mark Sisson is an American fitness author, entrepreneur, and former elite marathon runner and Ironman triathlete. After years of injury and poor health despite high training volumes, he shifted to ancestral health principles and built one of the largest paleo and primal health platforms on the internet at Mark's Daily Apple. He founded Primal Kitchen, a condiment and food company later acquired by Kraft Heinz. The Primal Blueprint, first published in 2009, has been through multiple updated editions and remains a central text in the ancestral health community.
