I attend one of the morning group classes and Chris is fantastic at managing my workout needs. The class will usually do warm-ups as group, maybe some group drills, but then he often segments everyone out based on our focus. I am constantly impressed with how well he remembers everyone's needs.
While Chris may arrive late to a few classes every now and again the instances are rare and he communicates with everyone in the class directly via text messages so we can make the most out of my morning workout, or snooze button.
