In this episode, Joe De Sena sits down with Dean Karnazes, one of the world's most relentless endurance athletes. Dean is an ultra-marathoner and is still competing hard at 60+.

You'll learn how micro workouts can transform your day, why breathing through your nose can upgrade your endurance, and how to push past your limits when your mind wants to give up.
