Andrew and Brad discuss how to “solve the puzzle” of transitioning gracefully through major shifts in career or life. In the athletic world, many struggle on the occasion of retirement because the intensity of competition and attention is difficult or impossible to match in more traditional career pursuits. A process-oriented mindset is urged, so that self-esteem is not attached to results or one’s identity as an athlete, or a career achiever as well. Another suggestion is finding new passions—they don’t necessarily have to be competitive—but something that lights you up and engages you deeply. More discussion of how to balance career, family, fitness/health, and personal goals, and how sometimes we look at health and fitness pursuits as “sacrifices” when in fact not doing healthy behaviors is the real sacrifice. Enjoy a thoughtful show full of practical tips from Andrew and Brad.

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, offers details about Christopher’s full program, including an excellent free print book (just pay S&H and he’ll mail you an actual book!) to get you started. So tune in to get a jump start on a common problem that may have a simpler (and more painless) solution than you might have thought!

The dynamic duo of Brad and Brock do another “all host, no guest” format for this show. They tee up the exciting topic of low carb endurance training, and how to transition away from the carb dependency paradigm that frames the conventional approach to endurance training. Brock and Brad describe the numerous health, body composition, and performance benefits that come to athletes eating a more nutritious diet and ditching the toxic refined carbs (and high polyunsaturated vegetable oils) that damage the health of even the fittest endurance machines.

Carb dependency is a two-fold problem: First, chronic training patterns causing frequent depletion and consequent disturbance in appetite and fat storage hormones. Second, consuming too many processed carbs causes insulin spikes, fat storage patterns, and cravings for more carbs. In determining the optimal amount of carbs, the first question to ask is: do you have excess body fat or not? The primal approach never discounts the importance of recovering from training (and choosing the most nutritious carbs for this purpose), but is an attractive solution to finally, once and for all, solving that puzzle of carrying excess body fat despite a big devotion to endurance training.
