Primal Blueprint Podcast

Mark Sisson tries something new with this podcast episode, as he reads an essay based on one of his most popular posts ever on MarksDailyApple.com: “A Case Against Cardio.” The original post, published in June 2007, helped shed light on the concept that extreme endurance training can actually compromise health and increase disease risk. Mark published several follow up posts over the years on the topic of chronic exercise and the ways to avoid the stress and damage caused when exercise patterns drift away from optimal stress/rest balance and into the extreme category. Mark’s essay covers the original landmark post, along with assorted commentary from follow up posts. For devoted fitness enthusiasts with passions for Crossfit, marathons, triathlons, heavy gym class participation, or even high-energy weekend warriors who are balancing exercise goals with hectic daily life, this is a very important podcast to absorb and ponder carefully how your own exercise and stress management patterns are looking these days.
