No place for self-doubt in fitness

Editor's note: Carlos Solis is one of seven CNN viewers selected to train for and compete alongside Dr. Sanjay Gupta in the Nautica Malibu Triathlon in September.  Carlos is a middle-school teacher in Ontario, California, and is also a Type-2 diabetic.

It’s the first week of August, and I’m already back in the classroom preparing for the students who will be walking through my door on Monday.

This year I wanted to do a room theme for my sixth-graders, but couldn’t come up with anything. Then it hit me: why not go “sports”? Since athletic fitness is my passion as I prepare for the Nautica Malibu Triathlon, it seemed like a good idea to carry that enthusiasm into my classroom.
