Dr. Richard Hansen (@DrRichardHansen) joins us again and speaks on a variety of topics. Not only is he a world class chiropractor, but he's also the coach of the Roots Running Project, a group of elite post collegiate runners based out of Boulder, CO. They have a great Instagram feed - @roots_running .

Thanks Dr. Hansen for your time and best of luck to your athlete competing in Eugene at the US Olympic Track and Field Trials.
