I was wondering the same question for a few weeks already, and I didn't look for an answer until I stumbled upon a video via Pinterest (love this website! you can follow my ''Pins'' HERE!)
And OMG it felt like.... I don't even know which word I should use for describing the feeling I had when I saw it...
Anyway, after seeing the video, I REALLY wanted to learn more about CrossFit and I guess some of you out there wants too, here another video I found on YouTube that explained a little bit more!
And CrossFit Games 2012 (Canada East Regional!)... Wish I knew this at the right time :P
