Ayten Karmadzhi


I have been interested in fitness for over five years. The reason to start leading healthy lifestyle and indulging in sports was mostly healthy. After I graduated high school and my first year as a student at university, I had health issues and I gained weight sharply. I did not know how to nourish myself and where to start. But I knew the way I wanted to look. I decided to go on a student exchange program in the USA. During that time, I worked in the summer and in the winter I was able to successfully pass my university exams. I learned how to eat healthy and build my dream body. It took me months even years but I knew what I want! Every day when I woke up I made a plan for the present day and what I should do to be one step closer to my goal. I managed to lose 20 kilograms with a lot of efforts, discipline and persistence and to improve my health.
