## Resource

Full Show Notes : https://bengreenfieldlife.com/sisson2026   In this episode with Mark Sisson , you'll discover why VO2 Max may be overrated as the gold standard for longevity, and why chasing it cost Mark 32 pounds of muscle and the real-world function that actually matters. You'll explore his "Old Man Olympics" framework: a decathlete's approach to fitness at 72, spanning strength, speed, balance, and endurance. You'll also get his take on cold plunging, alcohol, biohacking, AI, and find out why foot health may be the single most overlooked lever in your longevity toolkit, from bunions to glute activation to big toe function. Mark Sisson ignited the ancestral health movement with Mark's Daily Apple and The Primal Blueprint , popularized keto and intermittent fasting with The Keto Reset Diet and Two Meals a Day , and sold Primal Kitchen to Kraft Heinz for $200M.
