When you meet someone for the first time, it's easy to think that the person you see in front of you is the same person that you would have seen if you met him or her a month ago, or a year ago, or a decade ago. But that's simply not the case. Every confident, fit athlete you see in a CrossFit gym started out as an intimidated, out-of-shape beginner. It isn't that CrossFit is only for really fit people — it's that anyone can walk into a CrossFit gym and, with hard work and time, become a really fit person.
