KT Stemper
WITS Certified Personal Trainer

Hometown: Ottawa, IL > Cooper City, FL

When and why did you come to Austin?
I moved to Austin in 2013 on a complete whim. I had never been here before, but I immediately fell in love with the city’s commitment to fitness, the protection of green spaces and the genuinely kind and curious attitude of the people living here.

What is your background? How did you get into personal training?
I was admittedly a band nerd through grade school! I started lifting after I started playing the tuba and realized I’d have to get stronger to be able to handle it like the guys.

When I moved to Austin I was fortunate to get a job as a physical therapy technician. Learning from some fantastic PTs made me realize how important the transition is between rehab and an active lifestyle. I pursued certification in order to play a more direct role in getting people active and keeping them healthy.

The training style I use shifts depending on the clients goals and capabilities, but I certainly believe in the idea that “strength is never a weakness.”

You also serve as the head of Human Resources for ASF. Tell us about what you do in this role:
Our goal as a company is to be the best place to work as a personal trainer in Austin. My role is to help write policy and programs that support this goal. In the past couple of years I’ve also directed our hiring process, which has allowed us to expand both our offerings to our clients as well as to create new opportunities for education within the staff.

Tell us about your current fitness goals and training:
I’ve been training jiu jitsu since 2019. This sport presents a whole new host of programming questions and has been a fun intellectual challenge. My goal is to be as mobile and well-conditioned as possible while maintaining a high level of strength relative to my weight class. And big biceps, of course…

What is the most common fitness myth you work through with your clients?
That a previous injury prevents a person from normal function. Often we exacerbate functional deficits by protecting a range of motion or a movement pattern with disuse. Movement is medicine, and with slow progression and alterations in form in particular movement patterns, we can make a lot of difference in day-to-day ability!

What do you want your clients to take away from each training session with you?
I want my clients to leave our sessions with the belief that they have the power to make the change they desire in their lives. I help my clients to create a plan of action for themselves and assist in holding them accountable to the goals they set.

What is your favorite thing about Austin Simply Fit? 
Austin Simply Fit is a diverse group of trainers from many different backgrounds. Every time we add an individual to the team, it’s an opportunity for each of the current employees to learn something new and expand their repertoire as well as step into a teaching role themselves. I’ve watched us grow so much as a community and I’m grateful for the opportunity to learn from my coworkers.

Favorite quote and who said it? 
“The only work really worth doing — the only work you can do convincingly — is the work that focuses on the things you care about. To not focus on those issues is to deny the constants in your life.” – David Bayles, Art & Fear


I’ve had many good personal trainers over the years, but KT Stemper tops them all. Her knowledge of the body and the latest training techniques are second to none. Also, the facility is immaculate and well stocked with equipment. You can’t go wrong with KT and Austin Simply Fit!
