Kourtney Thomas

Saint Louis, MO 63119

A former avoider of gym class, Kourtney stumbled her way into the fitness world via TV infomercials and never looked back. Within a couple of years, she’d made the career transition from desk to gym.

With that decision, Kourtney completed her personal training certification through ACSM, followed that up with her running coaching certification through the RRCA, and then became a Certified Strength and Conditioning Specialist through the NSCA. Kourtney also holds certifications in Concurrent Hybrid Performance Coaching, Spinning, TRX, and ViPR Training. Her business, Kourtney Thomas Fitness, focuses on empowering people to not only master movement, but mindset and choices, too, in order to build a big, beautiful life.

Her passion for endurance running (Kourtney has completed numerous 5k and 10k races, many half marathons, and four marathons to date) evolved into strength training and eventually bodybuilding, and Kourtney believes that there is a style of movement that will ignite a fire in anyone.

When she’s not at the gym doing some variation of biceps curls (seriously, it’s a lot of the time), Kourtney rides her Harley-Davidson Softail Deluxe anytime the weather is above 50 degrees, travels to national parks, stays up too late reading copious amounts of science fiction and fantasy, and bake elaborates cakes and cookies. Her motto is “Big Arms, Big Life,” and she lives that daily alongside her husband, Marty, miniature dachshund Boudreaux, and orange tabby cat, Brewer, outside of Saint Louis, MO.
