"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 ´to be fit for life´. Which means to be pain free, full of energy, to live a long and healhy life with no major health problems. I would love everybody to realize that a healthy lifestyle is the number one step to a happy life. A healhy lifestyle doesnt mean beeing at the gym 24/7, it doesnt mean counting calories all day long and it also doesnt mean spending tons of money for supplements in order to "look" good. In my opinion the secret to a healhy life is way more simple: whole food moslty plant based diet, good sleep and recovery, movement of any kind and a positive attitude. 

We live in the age of very poor movement habits, very bad nutrition and in the same time in the age of numerous diseases. It is not a coincidence, our body is the mirror of our lifestyle. 

Unfortunatelly instead of health, people strive after a "perfect look" that has been created through social media and the society. But what is "perfect"? For me close to perfect is HEALTHY. Each individual on this planet is different. We all have different bodies, different genetics, different jobs, etc. That means we all have different goals and we will most definitely have different results. The plague of today is the lack of movement. Many of us stop being physically active by the time they start a sitting job. Even children spend more time sitting nowadays. But what if you move too much? Or the wrong way? What if you play sports and get injured once in a while? The right answer is always: take care of your body! 

My goal as a personal trainer is to help my clients to find a way to a healhy lifestyleway in each individual way. I am sure with my experience and expertise I can help as well a mom to get in shape after pregnancy as a young athlete who is just preparing for his professional sports career. 

Long story short: eliminate the health and body issues, learn how to move right, build a foundation for body stability and functionality, find joy in movement, always strive to become a better version of yourself...and dont forget to smile :)
