Katie loves being part of the Train Insane team! She is a wife and mother of two energetic boys.

What started as a way to manage stress and TMJ quickly became her number one hobby. While Katie originally came to Train Insane for the intense workouts, it’s the community and energy that kept her coming back. There’s nothing quite like being surrounded by amazing women pushing themselves to reach their goals. Katie wants you to celebrate the little wins and have the confidence to push to new limits.

Kate is a spunky Georgia peach with a passion for helping people live their healthiest lives possible. A recent graduate from BYU’s Marriott School of Business, she works full-time for Intermountain Health as a Consumer Experience (CX) Designer. Growing up, she was always super active. While living overseas, she competed internationally in both soccer and swimming but quickly fell in love with running. By the time she moved back to the states, she focused solely on running and was competitive in the 1600m/3200m/5k until she broke her foot due to overtraining. This injury taught her the importance of prioritizing weight training with any sport and she has yet to be injured since. Kate is a huge advocate for listening to your body while pushing it to its limits. She has found Train Insane to be the perfect, healthy push for her fitness goals and can’t wait to help others reach theirs!

Nicole has been around fitness her whole life. She grew up watching her mother as a personal trainer and her father run many St. George marathons as well as the Boston Marathon. Raised in St. George Utah, Nicole was never expected to be active but she couldn't help but gravitate toward health and fitness. She has spent the last 10 years understanding what "being truly healthy" means. After marrying and having 3 children Nicole realized health and wellness isn't about a number. She found it is more so about pushing your body, enjoying, motivation, breaking barriers, competitiveness, mixing it up, doing your best, and becoming a better version of yourself. Nicole brings her love and desire to be healthy, strong, and happy to every class she teaches and is an amazing addition to the Train Insane tribe!
