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!

"They say if you surround yourself with the best, you’ll become the best… that is Train Insane to me."

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!

My name is Jessi and I am the lucky SOB who gets to run the show over at our Chandler AZ location! I love AZ and have lived here in the past, so when the opportunity came up to move back down to open our Chandler location I absolutely could not pass it up. I thrive in the heat and the hot sunshine! I love a good ass kickin, so naturally I am a true Train Insane junkie. Since I first got certified, teaching has become my favorite thing and something that just makes me come alive. I absolutely love helping and watching people push, empower, and challenge themselves everyday in class. Health and fitness is something I value a ton and I feel lucky to get to share that world so closely with other people.

Breezy Rhodes

Instructor, Train Insane

There are so many emotions tied to exercise. I grew up playing sports. I got my degree in Exercise Science. I rarely miss a day where I’m not physically active, whether on my own or with my husband and our three little boys! It’s so much more than looking good (although that’s a perk!) It’s where I reset mentally. It’s how I connect with people I love. It helps me remember I can do hard things. I experience each of these emotions every time I step inside Train Insane. I can’t wait to be a part of that for others!

Emily is beyond excited to be joining Train Insane as an instructor. She loves being a wife and mom of 5, and pregnant with number 6! She grew up doing competitive cheer and loved being physically active as a young girl. While cheering in high school she found a love for running and weight lifting. But at 16 years old she became very ill with Guillean Barre syndrome and was temporarily paralyzed stopping all physical activity. After being in a wheelchair, walker and over a year of physical therapy and treatments she had to relearn to walk, run and function again. She met her now husband and they started their family. After her first baby at 19 she found group fitness again and it sparked a fire in her. She loves the motivation and drive that comes from Train Insane classes and the energy and sense of community it brings. In her words, “group fitness, healed apart of her she thought she lost after getting sick.” “It’s not just about your body changing but our mental health as human beings, it’s the best form of therapy and self healing”, she says. She’s been doing weight lifting, HIIT classes and running half marathons for the last 8 years. She’s beyond excited to be at Train Insane, where she can help motivate others to get a great workout, push themselves, and feel the “high” from getting a great burn and training INSANE!

Dani has been married for almost thirteen years and has two beautiful girls that are the center of her world. Working out became an outlet for her just over seven years ago. It started with running, then lifting and her obsession with group fitness took off from there. She walked into TIAZ two years ago and instantly knew she had found her new home. One of the things she loves most about Train Insane is watching members transform. Their confidence grows each and every day, as an instructor, she believes there is nothing more rewarding than that! She is so grateful to be part of the TIAZ team and I can’t wait to push members closer to their goals!
