Client Testimonials

Hear What Others Have to Say


Personal Training


The picture on the left was taken 2 years ago (2016). since than I've lost 30 kg and 3 dress sizes.
Katalin has been my inspiration and motivation on this journey. She helped me understand and start on a healthy lifestyle and supported me emotionally too. 
Increased my confidence tremendously.
I can definitely recommend Katalin as your personal trainer. She will address your personal needs and you'll work together to achieve your goals.
I cannot thank her enough.

Pregnancy Yoga


After a week long labour, the baby arrived yesterday afternoon (15.08.2019). She was 6lbs 7ozs. We are both very tired but doing well. Katalin all the stuff with the breathing exercizes got me to 6cm alone. So thank you so much. I can't wait for you to meet her for baby massage.
