I live down the street from one of the many crossfit studios that are springing up like autumn mushrooms here in Seattle. I’m not a fan of crossfit. In this regard, I agree with Steve Magness’s strong criticism of the crossfit movement. Nevertheless, I do have profound respect for Kelly Starrett, a doctor of physical therapy and self-professed avid runner, who is at the core of the crossfit movement. This review is about two of his books: Becoming a Supple Leopard and Ready to Run, which I think belong on every endurance athlete’s bookshelf.
