RAINA HAMPTON
Instructor
Hi I’m Raina Hampton! I’m originally from South Louisiana and have been married to my bestie, Allen, for 21 years now and we have 4 kiddos and 2 Bernese Mountain Dogs! It was our dream to move to Colorado and we did so 6 years ago. We both work with Young Life college and have for 20+ years - I got Interested  in group fitness after my first son was born and I needed some toning up and some social interaction. Allen was in Afghanistan at the time, deployed with the Army so I was alone with our oldest son and had to get my crazies out some way! Haha! I loved the motivation and challenge of sweating alongside of other people every day and I got addicted! We moved to Oxford Mississippi for Young Life, and we started CrossFit and TRX classes which helped as I had my 3rd and 4th babies there! My best friends came from those early mornings together and I could fit in skinny jeans again! We moved to Erie in 2016 and my CrossFit instructor encouraged me to get my Group fit cert so I did and have been teaching ever since! I love everything active: skiing, backpacking, hiking, and for fitness I enjoy Hiit and indoor cycle the most. I truly just love to be with people and help encourage them in any way I can to achieve their dreams and desires in this crazy life!
