Every mammal in this world deals with adversity.
The harder to you try to avoid it, the harder it will hit you when it finds you. And make no mistake about it, adversity will find you.
So it's not about living an adversity free life, because that is impossible, it's about learning how to handle and best respond to the adversity when you face it.
This is one of the things that makes CrossFit special. In each workout, you will find yourself dealing with some form of adversity. Constantly performing workouts that exposes you to adversity teaches you how to handle it better the next time you see it.
CrossFit workouts are not easy. They test you both psychologically and physically. You want to quit in the middle of the workout so you learn how to keep moving forward. You want to avoid the workout so you learn how to show up and face it. The workouts expose your weaknesses so you learn how to develop them. You get frustrated in the middle of your workout so you learn how to breathe and control your emotions.
This is one of the ways CrossFit develops you inside and outside of the gym. Learn how to deal with your daily WODs, and you will learn how to deal with life adversities.
