Co-owners, TwinFitness

Kristie Stirewalt-Winter and Michelle Stirewalt-Hutton

Commonly known as the Trasey Twins, Michelle Stirewalt-Hutton and Kristie Stirewalt-Winter are co-owners of TwinFitness, a female-centered, private personal training studio in Overland Park, Kansas. Founded in 2003, TwinFitness has a goal of inspiring every woman to be her very best. From their two locations and alongside their 13 employees, Hutton and Winter offer comprehensive personal training, nutrition coaching and preparation for fitness, figure and bikini competitions. 

With their K-State bachelor's degrees in exercise science and nutrition, the twins utilized their education to specialize in training the female body for competition. They have furthered their education through certifications in endocrinology, nutrition coaching from Precision Nutrition, and personal training and group exercise instruction from the American Council of Exercise. To provide comprehensive resources to their clients, the twins created an online nutrition program that compliments their personal training business and developed their own supplement line, formulated especially for women.

After graduating from K-State, Stirewalt-Hutton and Stirewalt-Winter began competing in fitness and bikini competitions; they have collectively walked the stage for over 80 shows, earned more than 900 trophies from National Physique Committee, or NPC, competitions, and for eight years straight have won the best team award at the biggest NPC show in Kansas City. In 2011, both Winter and Hutton earned their International Federation of Bodybuilding and Fitness, or IFBB, bikini pro cards, marking each as a professional bikini competitor. As industry experts, they have trained over 5,000 clients and customers. The twins are a dynamic pair who have written three cookbooks together and been featured in many fitness-based magazines, including Flex, KC Fitness, NPC News Online and Oxygen. They have the expertise, education and personal training experience to lead their TwinFitness clients to success in achieving their goals.

Stirewalt-Hutton is married to her high school sweetheart, Doug, and they have two daughters, Skylar, 8, and Tenley, 5. While Hutton enjoys exercising with her running partner, Ace, the family dog, and the entire family spends lots of time together riding bikes and playing outside with friends. Stirewalt-Winter is living the country life with her husband, Brady, and twin daughters Ali and Rylee, 6. They like to ride bikes, hang out at the lake, ride horses and cook together.
