Zack running in the Toyota U.S. Open Triathlon

My name is Zack Istre and I specialize in helping people achieve their health and fitness goals. I received my certification as a Personal Trainer from the world renowned Cooper Institute, which has been educating individuals in preventive medicine since 1970, as well as my Level 1 Coach Certification from USA Triathlon.
I recently relocated to Austin, TX from Dallas and hope to inspire others to reach their own best level of health and fitness.
