Dr. Kelly Starrett is a coach, physical therapist, author, speaker and co-founder of San Francisco CrossFit, MobilityWOD and the nonprofit StandUpKids. Kelly has trained every single branch of the military, pro ballers in the NBA, NFL, NHL, Olympic gold medalists, ballet dancers and the list goes on and on. His clients include Laird Hamilton, Tim Ferris, Barbara Walters and Barack Obama. He opens up about his sordid childhood, his anxieties, where he got his nickname “Supple Leopard” and, oh yes, his love life. I hope you enjoy this rare inside look of Kelly’s life inside and outside the CrossFit box.
