Summary

Listen to the full episode: https://www.youtube.com/watch?v=_XENYK73THs At 70, Mark Sisson looks better than most people half his age. In this Fitness Friday episode, I’m sharing an excerpt from our conversation where he shares the counterintuitive strategies that kept him injury-free and thriving while his endurance athlete peers broke down. We dive into the concept of metabolic flexibility, why he's now on a "campaign to eradicate running" and believes walking is the single best thing humans can do for themselves, and the “eat to live” mindset that can change your relationship with food. Mark Sisson is the OG of the ancestral health movement, creator of the Primal Blueprint, and founder of Primal Kitchen (sold to Kraft Heinz). His newsletter Mark's Daily Apple has been teaching people how to optimize their health since 2006, making him one of the earliest voices in what's now a massive wellness industry. What we discuss: Why Mark Looks Decades Younger Than His 70 Years The Injury That Changed Everything and Led to His Anti-Running Philosophy What Metabolic Flexibility Really Means (And Why He Popularized the Term) How to Access Any Energy Source Your Body Needs at Any Time The "Eat to Live vs Live to Eat" Mindset That Transformed His Relationship with Food How Orthotics Actually Weaken Your Feet Instead of Helping Them Why Modern Medicine Treats Symptoms Instead of Root Causes Thank you to our sponsors: Therasage: Head over to therasage.com and use code Be Bold for 15% off Air Doctor: Go to airdoctorpro.com and use promo code HUSTLE for up to $300 off and a 3-year warranty on air purifiers.
