I'm Natalia Wisniewska, a personal trainer, athlete, and passionate advocate for health and fitness. From a young age, I was drawn to sports, dancing, and track, and at 16 I started kickboxing in Stuttgart, eventually competing internationally for Germany and the US in pointfighting.
I studied Fitness Economics and became a certified trainer and nutrition coach, turning my passion into a career.
Between 2013 and 2018, I lived in Chicago, coaching athletes, professionals, and corporate clients. I worked as a Nike trainer, was part of the JW Marriott Fit Squad, and taught kickboxing at Title Boxing Clubs. I’ve also appeared on several TV sports shows, including Ninja Warrior in five countries, Superhero Germany, and in 2024 Exatlon Germany.
Today, I coach and speak at Women’s Health Camps across Europe and lead health and mental health workshops for large companies such as Daimler and MHP. I am also active as a Nike representative, leading training events.
In addition to coaching, I’ve been competing as a Hyrox athlete for several years, including participation in the World Championship. I constantly challenge myself there, pushing my performance and setting new personal benchmarks.

TESTIMONIALS

„Wenn du denkst, es geht nicht mehr, kommt von irgendwo Natalia her!“
Paul Zipser, Chicago Bulls, NBA
Mario Little, VL Pesaro, Italien
"When it comes getting the body right Natalia is the best in chicago. The science and technic behind her work is what I like best! Her will and determination for strength and wellness will take her far in this profession."
Phyllis, 77, Artist from Chicago
"I trained with Natalia Key-Wisniewska for almost 5 years. She was working at a fitness center near by and had just joined the organization. I had never worked out before, and I was one of her first clients. From our very beginning meeting, I liked Natalia’s direct manner, her good natured wit, concern and watchfulness. By the time Natalia left returning to Germany, I was feeling so much stronger and confident, and my body shape, balance and stamina greatly improved. My only complaint… she didn’t help to make me taller…. or younger!"
For me, fitness means being fit for life – living pain-free, full of energy, and healthy. On one hand, I help people build a sustainable, balanced lifestyle: eating mostly whole, plant-based foods, prioritizing sleep and recovery, moving their bodies in ways that feel good, and cultivating a positive mindset. On the other hand, my inner athlete drives me to help athletes push their limits and take their performance to the next level.
Fitness isn’t about spending hours in the gym, counting calories, or chasing a “perfect look” promoted by social media. It’s about understanding your body, moving well, building stability and functionality, and finding joy in the process. Everyone is different – different bodies, genetics, goals – which is why my approach is always tailored to the individual.
Ultimately, my goal as a personal trainer is to help clients move better, feel healthier, perform stronger, and continuously strive to become the best version of themselves… and never forget to smile along the way :-)
