LONGEVITY EXPERT: The Minimum Effective Dose of Training For Fitness & Longevity at 73 | Mark Sisson

The people grinding hardest for their health are often the ones training themselves into breakdown. What if the endurance work you trust most is the very thing wrecking your heart?

Mark Sisson is the founder of Mark's Daily Apple, Primal Kitchen, and Peluva, and one of the original architects of the ancestral health movement. He's a former elite endurance athlete who, at 73, now argues that the training that built his name nearly wrecked his heart. We talked about the minimum effective dose: why most people should stop running, how diet drives 80% of your results, and why your feet may be the most overlooked lever in staying strong for life.

What we explore:

- Why most people should stop running, and how endurance training drives overtraining and CNS stress.

- How chronic cardio contributed to Mark's heart arrhythmias, common among lifelong endurance athletes.

- What metabolic flexibility is, and why diet drives 80% of body composition.

- Why foot health is the overlooked key to longevity and fall prevention.

- How to tell a hack worth doing from biohacking noise.
