I dropped in for two classes at CrossFit Southend. The place is monstrous, something like 7500 square feet, and was a bit intimidating at first as a result. They had no fewer than three classes going simultaneously. But upon walking in I was instantly welcomed by a member who introduced me to Sarah, one of the coaches. Long story short, it's a wonderful gym with all the requisite Crossfit equipment, exceptional coaching, and some cool members. I would absolutely drop in again when and if I'm in Charlotte again.
