  • Greg Enochs

    Greg Enochs

    American Council on Exercise, CPT

    My personal interest in fitness peaked when I started training for my first marathon in 2006. Having been used to years of weight training regimens, I was challenged when I had to switch my efforts for marathon training, focusing on overall health, stamina, and endurance. Since reinventing my fitness regimen in 2006, I have run the Boulder Marathon twice and am now training for a third time. I have also run a handful of half marathons and dozens of 5K’s and 10K’s and continue to run races throughout the summers.

    After six years of instructing hospital personnel on healthcare management systems, I began to search for career alternatives that would allow me to pursue a path that I found both interesting and satisfying. The passion I found for running and how it transformed my body and my life in general is what led me to pursue my personal training certification and the eventual move into the field of personal training at the end of 2008. I truly believe in overall fitness! As a result, you will always see a focus on total body strength, cardiovascular endurance, and flexibility while working with me. I believe we all need a companion in our quest for fitness and my promise is to give my all in making your experience at Qi a positive one!
