Doug Chapman was the 13th CrossFit affiliate. 

At his peak, he had 400 members at HyperFit in Ann Arbor, Michigan. Though that number has declined in recent years, he's best known for his online programming for athletes such as Julie Foucher. Camille Leblanc-Bazinet, Lindsey Valenzuela, Jennifer Smith, Nick Urankar, Neil Maddox, Chyna Cho, Jacob Heppner—they're all coached remotely by Doug. But his gym doesn't focus on competition. 

"If you focus on competitive CrossFit, you're going to ruin your business," he said. 

At the 1:09 mark, Nancy arrives. She's a retired lawyer and law professor, and she has a lot to say about training seniors with CrossFit. Doug steps aside for a few minutes and lets me talk to Nancy instead. As Doug moves more toward personal training and small group training (instead of teaching classes,) he talks about what makes a great trainer vs. a great coach and why many coaches should do more PT to improve their class coaching.
