There is nothing like the feeling of entering a CrossFit gym, WOD still unknown, bass beat booming, athletes from the previous session lingering, some still catching their breath, others chatting excitedly about feats completed. Trainers mingle, offering high fives for the day’s accomplishments and words of wisdom or inspiration to those about to begin the class. Everybody is giddy with anticipation or triumph. This feeling of exhilaration has been present at every CrossFit “box” I have trained at. However, since becoming a member of DNA Personal Training, it has become abundantly clear to me that there are critical differences between CrossFit venues.
