Great questions from listeners in this Q&A show, including the subtle and natural taste of B.rad Superfuel versus most ultra-sweet proteins, walking barefoot safely, if I can really “sprint” for 30,40,50 seconds? (no! that’s a HIIT session), are sleep requirements genetic? (yes—hear more in my show about sleep with RiseScience founder Jeff Kahn) and tips for custom designing a sensible cold therapy routine. I also talk about how Australia boasts 10% of our audience (guessing it’s probably because they love outdoor, active lifestyles), recommend blood tests for peak performers to strive for way better than today’s pathetic “normal”, and talk about if competitive mindsets are genetic or trainable (both!) and how to cultivate pure motivation as a triathlete by referencing my book, How To Improve Your (Triathlon) Time. Finally, I talk about the Blue Zones documentary—the inaccuracy of the cherry-picked and misrepresented “plant-based” attribute (Blue Zones eat well-sourced animal products), the real secret to Blue Zones longevity (such as extensive movement and strong social connections), whether or not I am completely honest about my own health and fitness journey, and if I’m willing to change my mind in regards to health information (if you’ve been listening to me for a while, you can guess this answer easily!).    TIMESTAMPS: Kenny wants to share his enthusiasm for B.rad’s Whey Protein, even though at first, he thought the taste too bland. You want to be careful when reading labels. “natural flavoring” or “natural flavors” is code word for chemicals.  [00:48] Are Peluvas superior to barefoot for making structural changes faster? [05:14] Aberdeen Shire Guitar Teacher asks: How long should you sprint to achieve the health benefits? A true sprint is anything that’s eight seconds or less in duration. [08:56] David Gifford works hard and really needs his sleep. How does that work with a spouse who is the opposite? [18:52] On YouTube, Red Eye asks about cold therapy sessions and the Shiver Protocol. [21:44]  Alan Placencia from Australia wants input on blood tests. Getting a fasting insulin number is very important. The triglycerides to HDL ratio is also important. [25:32] Male hormone panels indicate how you compare for your age group. Unfortunately, there has been a steady decline in the average male testosterone level. {[31:30] James Hall asks to what extent do you reckon that mindset and mentality is genetic versus what is learned and trainable? [34:07] Alistair Henderson talks about Brad’s Triathlon book and about the Blue Zone, the long living peoples around the world that have an active, energetic lifestyle [36:31] Free Speech Joe commented on Apple Podcasts that he appreciates Brad’s style of honesty and flexibility.
