Group Fitness Inst / 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.”

      Sara first came to one of the intro classes at Corps Fitness in October 2013. Her curiosity about CrossFit and her frustrations with her fitness progress doing just treadmill and elliptical workouts pushed her to try it out even though she was convinced she wasn’t ready or fit enough for CrossFit yet. Even though she was sore for a week after her first class, she was hooked. One of the things she loves most about working out at Corps Fitness is that everyone looks out for everyone and that any workout can be modified to any fitness level. Sara’s favorite exercises are “anything heavy with a barbell” and her favorite workout is Fight Gone Bad. Sara earned her CrossFit Level 1 Trainer certificate in July 2017 and recently completed the CrossFit Adaptive Training Specialty Course.
