Group Fitness Inst / CrossFit Level 1 Trainer / Former Marine Sergeant :

I went into the Marine Corps right out of high school as an overweight football player and returned lean, fit and able to take on any challenge. The philosophy that was ingrained in me changed my outlook on fitness and being active. I started Corps Fitness with the philosophy of exposing people to the motivation and self realization I experienced in boot camp. I was pushed beyond what I thought was my limit and that redefined what I knew I could accomplish. In 1998 I was diagnosed with a degenerative nerve condition and as a result of my Marine Corps experience I only became more determined to make the best of my situation. My goal with Corps Fitness and the IM ABLE Foundation is to inspire others to look inside themselves to push forward despite their challenges. No Excuses…Just MOVE!

Training Experience
Former Marine Sergeant
While in boot camp, Chris learned several valuable lessons that would shape him as a young man and in the years to come, including one very special lesson from his drill instructor. During a group cadence run in boot camp, Chris’ drill instructor, Dave Hart, uttered five words that continue to echo in Chris’ head during his most difficult times: “Don’t quit on me, Kaag.”

    My enlistment in the United States Army has helped shape me into the person I am today. Along with instilment of brotherhood and camaraderie, the Army has made physical fitness and integral part of my life. As an Army Sergeant one of my priorities was maintaining the fitness and well-being of my soldiers, and I continue to use this mentality as I lead and instruct others in workouts that focus on improving strength, flexibility, and functional range of motion.
      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!!
