239 Midlife Transformation: Ironman Playbook for Endurance, Longevity and Healthy Aging with Jeffrey Weiss

Can you build healthspan in your 50s, 60s and beyond? In our episode 239 conversation, Jeff Weiss says yes—and he's got the miles to prove it. After his first 10K at 48, Jeff progressed to marathons, ultramarathons, and Ironman triathlons, discovering how structured training within smart guardrails, and the right mindset can unlock cardiovascular fitness, strength, confidence, and cognitive resilience in midlife. We explore practical ways to get started (and keep going), how to balance discomfort vs. danger, and why setting "big, hairy, audacious goals" fuels transformation far beyond sport.
