Spartan Up!! Want a swift kick in the optimizing butt?! This is the book for you. It truly is "a take-no-prisoners guide to overcoming obstacles and achieving performance" delivered with enthusiasm by Joe De Sena--the renowned endurance/adventure racer who created Spartan Race. We'll look at what's impossible vs. just really hard, how to pass the cookie test as we develop grit and learn how to get to the next telephone pole in the race of life.
