Herman Pontzer PhD - Burn
Major advances in our understanding of human metabolism have been made in recent years, and they’ve been pioneered by Herman Pontzer, PhD. He, and his colleagues, are making discoveries in human metabolism and energy balance that will reshape our approach to human health for many years to come. These are fundamental breakthroughs that are providing explanations for outcomes among energy intake, exercise, and body weight that have confused us for so long. Get his new book on the show page:

Run With Ease (rebroadcast)
[Rebroadcast] Our goal is never to get good at suffering. Our goal is to suffer less under the same conditions, not to make running easier but to run with greater ease.

Keith Baar, PhD
Dr. Baar rejoins us on the show. He was previously on for episode 58. Today we illuminate the central role of connective tissue and associated proteins in transmitting force from muscle, extend that understanding to explain how muscle functions in running (hint: it’s not at all like most people think), and dive into ways that you can optimize your connective tissue health.

Shaping Hard Sessions
Two questions answered today. Should you put intervals at the beginning or at the end of the workout? Should progression runs be done by effort or pace?

Herman Pontzer, PhD
Herman Pontzer, PhD is an evolutionary anthropologist at Duke University interested in how the human body evolved and how our species’ past has shaped our health and physiology today. He studies the ecology, lifestyle, diet and evolutionary history of humans and apes to better understand metabolism and health. As you’ll hear in the interview, we emphasize what hunter-gatherer societies can tell us about the human body because it’s the lifestyle of hunter-gatherers that created the bodies we have. Several years ago, Dr. Pontzer and his colleagues were curious about the total energy expended per day by people living as hunter-gatherers. They discovered that nobody had made the actual, direct measurements. It took them a while to convince funding agencies that this was a good use of research dollars because the reviewers thought ’these are very active people, they’re going to be expending a lot more energy than sedentary people, we have good estimates of that based on activity level, we’re not going to learn anything here’. But Dr. Pontzer and is colleagues persisted, got the funding, and did the direct measurements. They discovered that the Hadza people of Tanzania expend the same number of calories per day as sedentary people in the United States and other modern societies despite being much more active.

Iñigo Mujika, PhD On Strength
Iñigo is back on the show, following up on his recent appearance in episode 127. In the previous episode, we talked about tapering. In this episode, talk about strength training from every angle, and we dive into two specific examples of training tweaks that made big improvements for athletes he coaches. Episode page:

Iñigo Mujika, PhD On Tapering
Iñigo Mujika (PhD) has coached numerous Olympians, national teams, and is recognized as one of the top triathlon (swimming, cycling, and running) coaches in the world. He's published over 100 peer-reviewed articles, books, and book chapters. He literally wrote the book on tapering, which is the main focus of our discussion though we touch on many other important and practical topics. Find all the links we talk about at

David Bishop, PhD
My guest today is David Bishop, PhD from Victoria University in Australia. He’s a world leading expert on the health and performance outcomes of exercise prescription with a particular emphasis on mitochondrial adaptations. Recently, he’s been studying the impact of twice-per-day training and that’s the main reason I brought him on the show. You’ll learn, for example, that running twice in a day may be more beneficial than training for the same duration in one long run. But we explore many other topics that will help you take your workouts to the next level. I spoke with him in the midst of the 2020 COVID-19 pandemic while he was on sabbatical and in lockdown in the north of Italy.

Jose Areta, PhD
Jose Areta studies energy availability, training, and performance. We talk about his recent case study of an amenorrhoeic athlete who restored their menstrual cycle while training and competing at a high level, his comprehensive review of glycogen utilization, and how an athlete can loose weight while training for performance and periodizing carbohydrate intake. SOUP is free of advertisements and sponsors, it’s supported by listeners who find it useful:

Mark Burnley, PhD
My guest today is Mark Burnley, PhD from the University of Kent, in the UK. His principle interests concern endurance physiology, specifically the oxygen uptake and metabolic responses to exercise and the power-duration relationship. For example, he was part of the group that first validated the 3-minute all-out test to estimate critical power. He's spent much of his career questioning why a large fraction of our exercise capacity is unsustainable. In other words, we can only maintain exercise when the intensity is less than 20-30% of our ability to generate force…why do we have so much additional capacity when we can't sustain it?
79:15 5/14/20
Patrick Wilson, PhD
Patrick Wilson (PhD) is an Associate Professor at Old Dominion University and author of a newly published book, The Athlete's Gut. He was a guest in episode 16. Today, we update our understanding of gut physiology from when he was first on the show but spend most of our time on lots of new and applied questions relevant to your training, racing, and adventures.
81:35 4/30/20
Andy Jones, PhD
Andy Jones is one of the world's leading experts in human performance physiology, especially in the realm of endurance. Nike recognized this when they brought him onto the Breaking 2 project. He's most famous in many circles for his pioneering work using nitrates to boost performance. Yes, this is the beetroot guy. Today we talk about mechanisms of fatigue, critical speed/power, evidence-based approaches to training, and (of course) beetroot juice.
