Hi! I’m Kristen Callahan. I live in Dallas, Texas. I’ve been here since 1998. I grew up in the suburbs of Chicago and surely never thought I’d be a Texan, but I am here to stay!

Education & Experience

Undergrad Studies

I went to Alma College in the middle of the state of Michigan. I played 4 years of volleyball and majored in Exercise and Health Science. Athletic Training caught my attention and I worked with the Men’s basketball team and the Girls softball team. I learned tons about injuries, injury prevention, and injury rehabilitation. During my Senior year, I got my A.C.E. certification in Personal Training. 


Graduate School

I then moved to San Diego, to attend San Diego State University and pursue my Master’s Degree in Exercise and Nutritional Science. I earned my Athletic Trainer’s certification, but soon realized that I preferred to work with and help the average person as opposed to working with injured athletes. Good thing I got the A.C.E. certification, because I began my personal training journey immediately at a neighborhood gym in San Diego and then took my new experience and passion with me to Dallas in 1998.  I have had personal training clients ever since. 


Pilates Training

I received my Pilates Beginner and Intermediate Mat certification in 2014, then taught group Pilates classes at BodyBar Fitness. I currently have a reformer in my home and see several clients a week doing this format.


 

Yoga Certification

Yoga had been a big part of my life for many years and I finally took my 200-hour yoga teacher training here in Dallas at Karmany Yoga in 2015 then proceeded to teach at City Yoga and lead yoga retreats in Tulum, Mexico.  I have learned that incorporating yoga at any level into workout programs is vital for the mind, body and soul.

 

TrainerKristen Testimonials

I started Kristen’s TK90 Program in summer of 2019. I was never consistent with exercise and I never found something that was really fun to keep me going. NOW I sometimes even get up earlier to do my workout despite the fact that I‘m not a morning person at all! My goals were to get healthier overall, lose some weight and gain strength for ski season in Switzerland! I have gotten much stronger, I have lost more weight than I ever thought I would lose, and my skiing has been awesome this season! I feel better, healthier overall and have more energy too!
Kristen provides a great, customized workout program especially for me and my needs and motivated me from the beginning to keep going and try new things. She gives me feedback on all of my comments on the workouts and she had become part of my daily life despite the fact that we live on different continents!
What’s unique about Kristen is her positivity, her smile, and her passion. To be honest, I was not sure if online training was going to work for me, but I tried and it is so much fun and so easy to do. You don‘t need much space or time and you don’t even need to leave your flat. That makes it really easy to do your workouts every day. I really appreciate Kristen’s daily feedback and how she supports and motivates me. I just love her videos and that she also shares parts of her life with us on these videos too! She always gives suggestions for modifications and helpful tips. Also, the variety of videos is just awesome!
I think you just have to try it out and see for yourself how easy it is to move regularly. Even if it is just a short workout, it feels so good to do something and to see how you‘re doing better and how it gets easier every week. After the first workout, which contained a lot of squats, I could barely walk the next day and now I‘m doing sometimes some squats just for fun while waiting for a tram!

Corinne B – TK90 & Challenges

I have nothing but positive things to say about Kristen and TrainerKristen.com!I did TK90 from July-September 2019. I have always been a healthy fit person who exercised regularly. After becoming a mom, I struggled with fitting my health and fitness goals into the equation.TK90 is a no excuses plan! Kristen adapts the program based on how many days a week you want to work out and what equipment you have. (I was in Hawaii an entire month with ZERO equipment, but I still checked in!) The difference between doing a home workout and TK90 is the personalization. You have to check in with her after completing workouts, which kept me accountable. She also checks in on you! Her workouts are quick and effective. After completing TK90 I realized that despite how busy life is, self- care has to be done. I feel more active and energetic, and I have prioritized fitting exercise into my daily activities.

I got my identity back with TK90! Thank you Kristen!

Olivia C – TK90

Kristen and I go back 5 years now – when she started training me in person in preparation for my wedding. We reconnected last year when she kicked of her website with a Challenge. I participated in the Challenge then started her online program right after!
I needed something to ramp up my workout routine and also keep me accountable. The TK90 program was exactly what I needed to start working out 6 days a week and to make it part of my routine! Kristen is great to work with in person and through her online programs. She makes each workout fun and reminds you why you’re doing it!
I completed by TK90 program and have been doing the basic DIY training for a few months now and am proud of the results. I have become much stronger and seen a couple inches fall off in the process! It’s also been impactful for my mental well-being.
Needless to say, the TK90 program is one of the best investments I have made for myself both physically and mentally. I highly suggest it as well as the DIY subscription!

Elise S – TK90 & DIY

TrainerKristen.com came along at the PERFECT time for me!  In the past, I had always been able to find the time to go to the gym or make it to a class, but between work and being a mom to my 4 year old who started school this year, it was getting way too easy to make excuses!  I absolutely love the flexibility that this program gives me.  I don’t have to leave the house to get in a great workout whenever it works best for me.  And Kristen is just the best!  So energetic and encouraging and supportive and a really great trainer.  I’m so grateful to have her in my life!!  

Tiffany A – TK90, DIY & Challenges

Her positive and kind approach has been very motivating. I feel more confident in the gym and definitely have tried things that I would never have done on my own. I feel stronger and she has inspired me to achieve my fitness goals.

Since taking Yoga from Kristen, my joints feel better, and my energy has improved. I like the way Kristen designs the yoga around me, for example when I have an issue with a certain muscle she works that into the routine, impromptu! She is very knowledgeable about her subject. I enjoy working with Kristen very much!

Jeananne S.

When I started working out with Kristen, I needed someone to keep me accountable and encourage me to incorporate fitness into my life. As we’ve worked together over the last few years, I’ve become stronger and more confident in my abilities. I’ve set hard goals for myself, and I’ve achieved them. Kristen is encouraging, resourceful, and a wonderful teacher. Her enthusiasm for fitness not only is evident in her commitment to her clients, but also is contagious.
