In this podcast, Regan Archibald dives into the three organ systems most crucial for longevity—the brain, heart, and muscles—focusing especially on how VO₂ max and grip strength predict long-term health and mortality risk. He shares personal fitness experiences, including using VO₂ max testing, dead hangs, and the Norwegian 4x4 interval protocol to improve cardiovascular performance and reverse age-related heart changes. Regan emphasizes practical strategies such as Zone 2 training, peptides for mitochondrial support, diagnostic testing, and building habits that protect metabolic and cardiovascular health. Through stories about his own training, his children’s fitness challenges, and the Ageless Future roadmap, he encourages listeners to set ambitious 90-day health goals, improve daily exercise routines, and commit to becoming the fittest version of themselves.
