Ep. 374: Mark Sisson - Stop Chasing the Health Hacks. Want to Live Longer? Start with Your Feet.

Rip sits down with longtime friend, former triathlon coach and Primal Kitchen founder, Mark Sisson, for a wide-ranging conversation about biohacking, longevity, chronic cardio, walking and foot health.

Rip and Mark go back more than three decades — and although their nutritional philosophies couldn't be much more different, Rip has always admired Mark's entrepreneurial spirit, curiosity and willingness to take risks.

In this episode, Mark explains:

- Why he calls biohacking “the day trading of health”

- Why he believes the basics should come before gadgets and supplements

- His problem with chronic cardio

- Why he favors lots of easy movement plus occasional high-intensity work

- How his own endurance career changed his thinking about exercise

- Why he now walks at least 45 minutes most days

- Why mobility matters so much for longevity

- Why he believes foot health has been largely ignored

- How Peluva grew out of his own search for better footwear
