About me

My name is Dr. Fritz Theden-Schow. I am a personal trainer with over seven years of professional coaching experience in functional fitness, and a PhD in food and resource economics.

Over my career I have worked as a coach and personal trainer at leading CrossFit and commercial gyms, including CrossFit Butchers Lab, CrossFit Copenhagen, Arca, and Fitness First. I have taught well over 1,000 hours of functional fitness classes, including CrossFit, Hyrox, ATHX, Olympic weightlifting, gymnastics, and mobility classes.

I have competed personally in a range of CrossFit, Hyrox, ATHX, Triathlon, and running competitions across Europe. That experience has given me a concrete understanding of what it takes to prepare both physically and mentally for peak performance when it counts.

What others had to say

I started with Fritz in January 2023 with no CrossFit experience and a fair amount of nerves. His persistence and friendly approach made training fun and built my confidence with strength work. After a year of personal training twice a week, I moved to his online programming. I now train on my own, and Fritz's coaching through the app keeps me motivated and constantly progressing. Today I can do pull-ups, lift heavy and genuinely feel strong.

I have trained with Fritz remotely since December 2022, with three weekly strength sessions alongside a very busy job. Years later, I am still progressing with the structured and efficient training program, which leaves me feeling strong and energized. And the best thing is that it complements my passion for cycling super well!

Knowledgeable, structured, and super friendly coach. Fritz prepared me for my very first Hyrox competition, tailored my training to my tennis preseason and built a running plan that led me to PR my half marathon time! He always adapted the program to my feedback, which worked super well for a full season of different sporting events!

With my demanding work schedule as an orthopedic resident, it's important to me that my training is realistically achievable. Through frequent feedback, we were able to tailor my training to fit my busy time schedule, and I was able to stick to the plan, which was something I had struggled with before working with Fritz. The sessions are well-planned and communicated clearly. I was surprised how well the remote set-up through the app worked!
