Host Brad Kearns talks to testosterone expert Christopher Walker, who details a remarkable story of self-healing from serious endocrine problems. Don’t flinch at the title—Chris’ approach is the opposite of the magic supplement obsessed blather you typically hear on the topic of testosterone enhancement. Chris was a college student at Duke and a hardcore triathlete when he first experienced some debilitating symptoms of low testosterone. When tested he was found to have a hideously low serum level of 11 ng/dl, where the normal range for his age group would be 400-1000 ng/dl. He was also discovered to have a pituitary tumor, which in addition to adverse lifestyle practices, was the cause of his serious disorder.
Chris boldly chose to forego the medically advised approach of either surgery or hormone replacement therapy and embark on a holistic lifestyle transformation. In a short time, he cured his condition and his testosterone level skyrocketed to 1192 ng/dl! Chris’s key to recovery included an assortment of holistic methods, including adopting a new empowering mindset and a diet full of primal-aligned foods.
Christopher offers these and other actionable tips for males to naturally elevate testosterone in today’s episode. Furthermore, testshock.com
Host Brad Kearns welcomes the red-hot author David Epstein to the show, on the heels of his whirlwind global tour to promote his bestselling book, The Sports Gene: Inside the science of extraordinary athletic performance. This is widely regarded as the seminal book on the topic of genetics in sports, and in it Dave dispels many widely held misconceptions and prejudices that people harbor relating to how genetics affects athletic performance.
In this conversation, Epstein discusses the pop culture of the “10,000 Hour Rule” (first presented by Dr. K. Anders Ericsson, Ph.D, and popularized by Malcolm Gladwell in the book Outliers.) Epstein dispels the accuracy of science behind the concept and the practical application of the concept. Basically, it’s BS! Genetic factors are relevant, as illustrated by the amazing “Tale of Two High Jumpers” featured in Chapter 2 in the book. Besides great physical attributes, there are genetic elements to the all-important athletic success factor of “desire to train.” People (like phenomenal ultra-athlete Pam Reed) have different dopamine response systems.
When it comes to stereotyping, for example, “Jamaicans are fast sprinters,” one must not overlook cultural factors. In Jamaica, youth track and field is king—there is no falling through the cracks or diverting to other sports. Epstein also writes for the progressive journalism nonprofit called ProPublica.org, which preserves the tradition of long-form investigative journalism. He had a huge impact with his recent article on the doping suspicions surrounding top track field coach Alberto Salazar. Enjoy the show and grab the book on amazon.com!

Description: The hosts with the most, Brad and Brock, return for another ridiculously interesting, free-flowing conversation on all matters of endurance training. First, they discuss how physically demanding jobs might impact training for endurance events—like nurses doing shift work or construction workers trying to train alongside the office workers. There are benefits to “moving frequently” in an active job, but the training schedule of highly physically demanding careers must be flexible and dynamic. When it comes to coaching people with busy lives, the transition away from robotic pre-programmed coaching schedules could alter the current business model, with coaches going from workout programmers to strategists.
Brad mentions how both Dr. Maffetone and Dave Scott agree that going relatively hard and going extremely hard have the same training effect. What if you backed off a bit on your high-intensity workouts? Would you lose mental toughness? Or would you recover faster, have less risk of setbacks (injury, illness, burnout) and thus get even faster? Maffetone thinks so in the premise of his book, 1:59 Marathon.
Brock recites “10 Myths About Elite Runners,” published in a Canadian running magazine, and the two banter about the assorted myths in hopes that recreational competitors can take to heart some of the misnomers about elites that compromise good decision making. This show offers an assortment of valuable tidbits to help you balance your training optimally with your important everyday life responsibilities.

Host Brad Kearns catches up with Host Brock Armstrong -- that's right, the main hosts catch up with each other and hit it hard on an assortment of interesting topics. They debate the pros and cons of various coaching models, stressing the importance of having a wide-ranging personal relationship with athletes to help training sync with other life variables. Brock FIRES clients who refuse to take time off!
The pair gets into one of their favorite subjects, Heart Rate Variability, referencing the Primal Endurance Podcast episode 6 with Sweetbeat Life CEO Ronda Collier. They talk about how monitoring HRV and basing training decisions off of variation from baseline values brings a critical objective element to the challenge of making smart training decisions. For example, when you are running on fight or flight chemicals, it's hard to tell if you are actually stressed because the hectic pace of modern life is so familiar that it seems normal to the brain. Get to know your Primal Endurance Podcast hosts Brad and Brock through this lively and informative show!
Host Brad Kearns welcomes Aaron Olson, the popular host of the Paleo Runner Podcast, to the show to discuss Aaron’s new book, Low Mileage Running. The book is “a short guide to running faster, injury free.” Aaron details his injury-riddled running career as a high school and college competitor, as he struggled to thrive doing the traditional high mileage programs.
Frustrated with repeated injuries, Aaron tried cutting out junk mileage but keeping high intensity workouts and including extra rest in his schedule. He discovered that his injuries went away and he ran even faster than before. Aaron believes in an intuitive approach instead of following a rigid schedule. Perform those intense workouts when you feel strong and you skip them if other stressors are present in your life or you simply don’t feel your best during the session.
Aaron’s Paleo Runner podcast expertly blends the worlds of endurance running and paleo eating and living. Aaron became a convert to paleo after a lifelong struggle with IBS that subsided almost as soon as he started to ditch toxic modern foods and adopt a paleo eating strategy. Check out his podcast on iTunes or through his blog paleorunner.org.

Host Brad Kearns records this fast paced essay on the importance of adequate sleep (especially for endurance athletes), in response to a recent episode of the Freakonomics Podcast.
Brad has always maintained a busy lifestyle balancing roles as a father, writer, and former triathlete, and discovered long ago that “sleep is everything.” Tune into today’s show for some quick tips and a personal sleep success story.
Host Brad Kearns welcomes popular guest Dr. Phil Maffetone to the show for the third time. Dr. Maffetone brings along both his insightful commentary and his ultimate endurance wisdom about balancing stress and rest while emphasizing aerobically-paced training. In this conversation, Phil talks about his incredible new smartphone app—called the MAF App—that does an assortment of evaluations to help you track health, fitness, disease risk factors, and stress levels.
Brad also challenges Phil on his profound assertion that endurance athletes need not ever exceed 90 percent of their maximum heart rate. Phil explains that the additional stress of going up to a maximum level does not deliver a sufficient return on investment. A healthy athlete can dig deep on race day and give a respectable 100 percent effort. Phil details the metabolic and endocrine effects of the stress response, and how to guard against the overtraining syndrome. “The game is how to moderate stress while training hard enough to perform your best,” Phil explains. Phil mentions how, for tracking aerobic improvement, time trials and other performance trackers are inferior to using a sub-maximal MAF test on a regular basis. Enjoy another lovely and informative show with Dr. Maffetone!

Host Brad Kearns speaks with the fastest golfer in the world, Rob Hogan, who’s from Galway, Ireland. Rob is the 2013 Speedgolf World Champion and 2014 runner-up. He covers a championship caliber course in under 40 minutes while shooting in the 70s! Rob is a professional athlete dedicated full-time to Speedgolf and running at an elite level. (01:00)
Rob details the fascinating flow-state elements of this sport that make it a truly Primal activity. Indeed, Speedgolf is a far cry from the time consuming, over-analytical, non-exertive game (which uses carts for transportation) that most are familiar with. (06:20)
Rob tells an engaging story about how he had powerful visions of a Fanta orange soda during a 17-mile training run, which he endured without added calories or hydration. Because he pushed on despite “bonking” (depleting blood glucose levels), he possibly rewired his appetite hormone, called ghrelin, which led his body to prefer fat and ketones instead of glucose. Remarkably, Rob reports that his sugar cravings ceased following that episode. (11:50)
Dr. Cate Shanahan weighs in with some commentary about the scientific aspects of this incredible anecdote from Rob’s run. (17.10)
Today, Rob’s dietary patterns are not strictly defined, but he avoids sugar and chooses his carbs carefully, emphasizing potatoes and sweet potatoes like a good Irishman. (18:00)
Brad asks, “How do we choose which carbohydrates to keep in our diet?” (21:30)
Rob talks about his daily training regimen for golf and long distance running. He says that a slow paced run is the best way to train in all sports that require running and stopping. (22:26)
Brad Kearns talks to British Olympic 400 meter runner Andrew Steele of DNAFit.com. DNAFit offers cutting edge genetic testing to identify your athletic and dietary attributes, enabling you to develop a strategy honoring your genetic particulars.
Andrew is the athletics specialist for the operation and is still an active professional runner pointing for the 2016 Olympic Games.

Host Brad Kearns welcomes Tawnee Prazak to discuss endurance training, racing, and coaching. Tawnee is the host of the popular Endurance Planet podcast and is a personal coach to triathletes and distance runners. Tawnee comments on many of the hot topics in the endurance scene today, including:
Mark Sisson follows up his essay reading last week with an engaging discussion with host Brad Kearns about the dangers of chronic cardio, and some tips to help avoid the drawbacks of chronic exercise patterns. Brad and Mark discuss numerous real-life case studies of elite athletes in endurance sports such as ironman triathlon and long distance running, who have suffered serious heart problems. Mark and Brad mention the tragic deaths of multisport athlete Steve Larsen at age 39 (heart attack while running), and Ryan Shay (heart attack while racing the US Olympic trials marathon), along with an assortment of other high profile athletes and their ordeals.
Mark presents a compelling solution in essay form, pulling highlights from some popular follow-up blog posts on the subject. Mark mentions eating Primally, downscaling the "filler" workouts that happen between challenging "breakthrough" sessions, and realizing that interval and sprint workouts can deliver a training effect superior to long-duration workouts, while also alleviating the risks of drifting into a chronic pattern. For a good takeaway sound bite, Mark reiterates a message from a popular post about burning a total of only around 4,000 calories per week during structured exercise sessions. This is a general rule of thumb that correlates with an impressive assortment of different types of workouts that develop broad-based functional fitness, and helps protect against the excesses of chronic exercise.
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.
Next week, Mark will continue the theme with a Chronic Cardio Part 2 podcast where he and host Brad Kearns talk about some of the real-life cases of elite athletes being stricken with serious heart problems, some of the science behind what happens to the body when it’s pushed too hard with insufficient rest, and how you can avoid these negative consequences.
Brad Kearns joins popular guest Andrew MacNaughton, founder and head coach of TheAthletesPotential.com. On his third podcast appearance, he does not disappoint, and offers an assortment of memorable tips and insights for how to train in a healthy, balanced manner.
Andrew describes how The Athletes Potential approach differs from conventional cookie cutter coaching based on workout programming and how he prefers to focus on total health and optimal lifestyle with his clients. He discusses his focus on how it’s possible to be too motivated and too driven to succeed, when patience is preferred.
Andrew and Brad agree that a major mistake endurance athletes make is to go too moderate too often. Consequently, when it’s time to actually go hard, people perform poorly because they have no reserve and insufficient fitness.
The two talk about how to overcome the excessive, obsessive training regimens that overrun the endurance world by focusing on performing well as a form of fun. He talks about his early career successes and encourages athletes to approach the sport in the right way: with an eye toward peak racing performance instead of filling logbooks, downscaling goal event distances to sync with life responsibilities, and trying to go fast instead of just surviving.
He also details a step-by-step plan to essentially take over the sport, but the microphone malfunctioned so his plans remain top secret…until perhaps the next show!
Host Brad Kearns talks with Gordo Byrn ultra-endurance athlete, coach, and prolific writer who cranks out a current series of incredibly insightful blog posts. On his blog, he covers the prominent topics in his amazing life’s journey while emphasizing Fitness, Family & Finances. After a decade in a highly intense and successful career as a partner in a private equity firm, Gordo walked away from a seat at the “Big Boy's Table” to pursue his calling as an endurance athlete.
Soon after his arrival onto the ultra scene, Gordo established himself as a world champion competitor, writer, popular coach, and performer of mighty endurance feats with the likes of sidekick-in-suffering Scott "The Terminator" Molina. Gordo's Ultraman World Champion title was earned in a 3-day competition consisting of a 10k swim, 90-mile bike ride on day one, 173-mile bike ride on day two, and 52-mile run on day three. He also took second at Ironman Canada at 8:29 and wrote the bestselling book, Going Long (with Joe Friel), considered by many to be the most comprehensive guide to preparing for Ironman distance events.
Gordo goes all-in with everything he does, and today he has settled into family life in Boulder, Colorado with his wife Monica and their three young children. He writes over 100 brief and extremely thoughtful posts on his blog every year, which you can visit at coachgordo.wordpress.com. Or, you can follow him on Twitter @gordo_68. Whoever you are, and whatever your goals, Gordo's insights will inspire you and get you thinking about the big picture.
Host Brad Kearns talks to Andrew MacNaughton about some heavy issues, including the influence of doping in endurance sports and the moral dilemma it presents for athletes. Andrew talks about his own career, and discusses whether he would have made the choice to dope if he were a young pro in an era where doping was necessary to be competitive. The two also discuss how, oddly enough, taking performance enhancing substances in elite sports might actually be more protective, than destructive, to long-term health by considering examples like NFL player taking weekly beatings, or endurance athletes inflicting massive oxidative damage to theirs bodies during routine daily training.
Andrew and Brad talk about how old school values like intuitive training decisions might be getting snuffed out by the obsession of technology, scientific systems, and Internet coaching today. Andrew was a close confidante to Canadian Simon Whitfield, who won the very first triathlon Olympic gold (Sydney 2000) and then a silver in Beijing in 2008. He talks about Simon’s incredible gold medal performance, the ups and downs he faced over the ensuing years, and the amazing ability to peak again eight years later. More thoughts are offered about the constant debate between volume versus intensity. You will be entertained and intrigued by the lively banter of these old friends who competed together on the pro circuit from ’86 to ‘93—enjoy the show!
In this episode, Mark Sisson has a discussion with Dr. Timothy Noakes of South Africa, who is an author and well-known expert in exercise physiology and human performance. As a physician, former longtime marathon runner, and co-founder of the Sports Science Institute of South Africa, Dr. Noakes has spearheaded efforts to advocate a low carb/high fat diet despite opposition in the mainstream medical community.
Host Brad Kearns talks to legendary old school pro triathlete Andrew MacNaughton. Andrew, a Canadian, was based in Los Angeles during his career on the circuit from 1986-1993. He and Kearns were training partners who both burst onto the scene in the late 1980s to compete at the highest level from seemingly nowhere. Andrew kicked off his 1987 season with seven consecutive victories, including taking down reigning Triathlete of the Year, Mike Pigg.
Known for his cycling prowess, many historians designate Andrew as arguably the finest pure climber the sport of triathlon has ever seen. Andrew amassed leads of over 10 minutes off the bike at Wildflower on a couple of occasions, led the brutally hilly 75-mile Nice World Championships bike ride by 7 minutes in T2, and torched many other bike courses—especially hilly ones—all over the globe.
After his career, Andrew became a sought-after coach with a unique, eminently sensible, and highly practical approach to the sport. Never one to mince words, Andrew is an extremely interesting interview with numerous memorable insights offered up in this show. He has agreed to be a regular guest on the Primal Endurance podcast.
In this episode, Andrew and Brad reminisce about the old days and the many changes, including the high tech influences, that have come to the sport over the years. They also talk a bit about Tim Noakes’ Central Governor Theory—how the brain is actually the ultimate limiter of performance rather than the muscles. Enjoy the show!
Mark discusses the role of doping in professional and Olympic sport. Far from a black and white issue, Mark explains that inconsistencies in the testing procedures and random demarcation lines for what constitutes a performance enhancing substance (e.g., Gatorade enhances performance when you are thirsty!). Also discussed is how the public perception that certain athletes cheat to gain an advantage is actually a more complex cultural issue than a true morality weakness. For example, in pro cycling, recent controversies have affirmed that an athlete was virtually compelled to boost blood with doping products to have a chance at being competitive. Furthermore, the highly selective and competitive nature of elite sports compels athletes to search for every possible recovery advantage, including those that cross the line into doping offenses.
Mark explains that we might view modern pro sports as theater, where athletes are performing for the pleasure of fans, with big money on the line, and hence we will always be fighting a battle - perhaps a losing battle - against dopers who might remain a step ahead of the testing efforts. And how there is a bit of hypocrisy with society at large, where use of "performance enhancing" substances (such as caffeine or prescription drugs to treat ADHD for example) is viewed differently than an athlete trying to recover faster.
Host Brad Kearns talks with Brock Armstrong (the voice of the MDA blog podcasts and a Sweetbeat ambassador/product tester) and Ronda Collier, CEO of Sweetwater Health, makers of the Sweetbeat Life iOS application. Sweetbeat Life allows for convenient Heart Rate Variability (HRV) measuring and information storage. This discussion will acquaint listeners with the basics of HRV, and proceed quickly to discuss some of the finer points of HRV’s effectiveness in monitoring stress and recovery. Heart Rate Variability is a measurement of the variation in intervals between heartbeats. More variation indicates better cardiovascular fitness and stress management, and is represented in a higher HRV number on a 1-100 scale.
Finer details of this show’s discussion include: how Low Frequency (LF) and High Frequency (HF) values correlate with sympathetic and parasympathetic nervous system activity; techniques for how to moderate your stress response and improve your recovery through breathing exercises, yoga, meditation, and extra sleep; and a step-by-step process for how to get started in HRV monitoring (buying the proper equipment, operating the Sweetbeat Life app smoothly, and understanding how to best use the informational graphs generated by the app). This is a fantastic show to help you jump head first into the amazing health technology of Heart Rate Variability!
Listen in as Brad Kearns and Dr. Phil Maffetone have a casual chat about an assortment of interesting topics related to endurance training and general health. Brad complains about his crash and burn patterns, where he feels great for a while and then has down periods of diminished energy and training output. Dr. Maffetone speculates that the cause could be an inappropriate maximum aerobic heart rate value, and urges a conservative approach when calculating your number. He also mentions low vitamin D as a common cause of fluctuating energy levels, and that athletes should strive to get up around 60 or 70 ng/mL. This is way above the mainstream recommendations and a very interesting insight for many sun-starved athletes to consider.
Regarding sleep, Dr. Maffetone urges everyone to get at least 7-9 hours of uninterrupted sleep each night. If you find yourself awakening in the middle of the night, it’s a sign of elevated cortisol levels and an overly stressful lifestyle. With high quality sleep each night, napping should be minimally necessary, but a nap of 30 minutes and no longer than an hour can be restorative.
Dr. Maffetone’s book, 1:59, discusses the possibility of a human running a sub-2-hour marathon and how it will happen. Maffetone suggests that a smart athlete backing off of the ultra-high volume of today’s elites (and running barefoot!) might gain some performance benefits. Maffetone also discusses the difference between the desirable overreaching in training to improve fitness, versus the undesirable state of overtraining (fatigue, depression, hormone imbalance). Brad and Phil discuss the interesting and confusing phenomenon that occurs in the first stage of overtraining. Here, sympathetic (fight or flight) activity is elevated, the athlete feels energized and aggressive, and PRs can even happen. Without a reasonable and intuitive approach, the athlete is headed for a crash when stress hormone production becomes exhausted. Enjoy this informative discussion with Dr. Phil Maffetone, including his own music framing the show! Learn more at PhilMaffetone.com.
