Pete Jones



B.S., Business - Information Systems, University of Colorado - Boulder

Pete has been coaching CrossFit for more than 10 years and started CrossFit in 2008 as a way to cross-train for marathons and Ironman Triathlons, and soon found it to be a much more enjoyable—and optimal—way to sustain a healthy lifestyle. In 2010, he convinced his wife to let him “train a few people out of the garage,” which has grown to training over 350 people out of 2 large warehouses.  He has coached over 9000 classes since then and has dedicated his career to helping people achieve their fitness-related goals.  Here is what Pete had to say about why he loves CrossFit:  “Since starting CrossFit, I look forward to every workout. Once I realized the on/off cycle was gone I knew there was something special about CrossFit. I think it is a combination of the daily competition against myself, the results, the camaraderie, and community. At some point I realized I was not only pretty passionate about it but also pretty good at coaching and helping people reach their goals.  I check the CrossFit Journal constantly throughout the day. I watch every training video I can get my hands on. I read nutrition books for fun. WHAT?!”  At the gym, he is known for overuse of the terms "ez-pz" and "you got this."
