This was borrowed from an amazingly inspiring woman from Lean Eating (who is a reformed paleo/crossfitter), Amanda:
The Badass's Creed
This is my body. There are many like it, but this one is mine.
My body is my best friend. It is my life. I must respect it as I must respect my life.
My body is human, even as I, because it is my life. Thus, I will love it as a sister. I will learn its weaknesses, celebrate its strengths, love its parts, and guide its sights. I will ever guard it against the ravages of all damage as I will ever guard my mind and spirit against damage. I will keep my body well fed and ready. We will become part of each other.
Before my Barbell, I swear this creed. My body and myself are the defenders of my life. We are the masters of my life. We are the saviors of my life. Bí láidir.
And may we all say, Amen.
