NETA Group Exercise Certification; American Sports & Fitness Association-Group Fitness/Bootcamp Instructor :

I enjoy training at Corps Fitness because the workouts are not only challenging but rewarding. I always leave with a heightened sense of accomplishment. I was immediately hooked and after the incredible change I saw in my mind and body, I now want to give back. My goals are to help others reach their goals, and have the same rewarding experience that I have had at Corps Fitness!!
