This conversation is an immersion into heat, cold, faith, family, and the steady pursuit of resilience. Pete Nelson II is a husband, father, entrepreneur, and 33 time ultramarathoner who founded SISU Sauna to bring ancestral wellness back into the modern world.

We explore the science and spirit of sauna culture, the nervous system reset that happens in cold water, the role of faith in leadership, how endurance shapes character, and what it means to build a business with integrity and patience.

This episode is for anyone who wants to live longer, but more importantly, live better. It is for the people who are ready to step into the heat, breathe, feel, release, and return to life renewed.
