I’ve been going to JK Fitness for a year! I’ve never before kept an exercise program going for that long! And when I’m away, I miss it! Thank you, Julia for cultivating such a wonderful team and a welcoming environment.

I am a high school athlete and JKFitness has helped me tremendously with learning how to properly fuel my body to preform my best in my sport, as well as teaching me proper strength training techniques. Julia explained everything so well to me and made this journey so much easier and stress free!

I’ve known Julia for 20 years, and she’s seen me through thick and thin—and thick again. She strikes the perfect balance: she pushes me enough to feel challenged, but always meets me where I am. No judgment, just steady encouragement and clear, doable steps. Julia consistently paints a picture of a healthier life I can actually see myself living, then helps me take action to get there. Because of her, I feel stronger, more confident, and more committed to my well-being. If you want a trainer who truly cares, motivates with kindness, and gets results, Julia is the one.

Julia and her whole staff at JKFITNESS is awesome! They use many different ways to get you into the best shape of your life. Ive done Metabolic testing to dietitians to exercise programs. And one of the best things is she will work remotely with you if you don't live in San Antonio!

Julia Karlstad and her team are phenomenal! I have been referring patients to JK Fitness for years and I have NEVER had a patient come back and say anything but positive things about Julia and her staff! They are friendly, knowledgable, very experienced and always approach patients in a non-judgemental way.
I have seen patient make dramatic transformations with JK Fitness and highly recommend them!

All of the trainers at JKFITNESS are truly the best! They have helped me so much - I have trained in person at the state of the art studio, as well as virtually! You receive personalized workouts that are for you based on your medical and physical needs. They have improved my balance, my core, my strength, and my nutritional needs, and I consistently workout with a trainer 4X a week. I will not miss as I continue to see such improvement. Thank you JKFITNESS!!

I had my annual cardiologist appointment today. My physician was very pleased with the lifestyle changes I’ve made, specifically working out 4x a week at JK Fitness! I do yoga, weight training and boxing every week. I love the different options for my exercise routine. The trainers are great, devoted to their clients and keep me coming back. Thanks for pushing me and making me sweat!

My wife and I have been part of the JKFitness client family for more than 10 years. Julia is amazing! We love the personal approach she takes in helping her clients work toward their fitness goals. The investment she makes in her clients is fantastic. She is supported by a great team. Between my wife and I, we are typically at the studio 2 -3 times a week for regular training sessions, yoga, and massage therapy, so we have had the pleasure of working with just about the entire team and they are all great at what they do. We really love our experiences and the people at JKFitness. It is a huge part of why we have been here for so many years and why we choose to remain.

Julia and her staff are exceptional . She is a ball of energy and when you run out of yours, she’s there to encourage you on. She is professional and knowledgeable on such an advanced level. It’s not just about exercise, it’s about total health. It’s a pleasure to work with her, but be ready to bring your A game.

My husband and I, in our late seventies, have been going to JKFitness for several years now. We have had great trainers: Kim, Javier, Leo, Colene, and Julia. Each one of them have guided us through a total body workout twice a week with both expertise and humor. We feel fit and strong for our age.

The best trainers who are never too busy to help adjust your workout plan. They work with my orthopedic limitations, allowing me to stay mobile and strong.

I had recently signed up for a V02 test. It didn't go as smooth as I thought it would. A couple of hiccups with the set up and actual test. I took my results with a grain of salt. For the amount I paid for I expected a better experience. On a brighter note the staff was friendly and accommodating.

Very pleased the VO2max, RMR and max heart rate assessment. It allows me to put a bit of science behind my running. The staff (Julia, Michaela and the others) are very friendly and helpful.
