About Alain

Helping people to be healthier and fitter has been a big wish of mine from an early age. It is my ultimate goal to help people to more quality of life by motivating them to be active and helpt them to reach their goals.

Already in my apprenticeship as a cook, my passion was dedicated to health and sports. After completing my apprenticeship, I therefore relatively quickly made my passion to my profession. My ambition and inner drive, as well as the motivation to create something of my own, led to the fact that I was able to build and develop my own business in this industry at a young age.
Since health can not only be associated with sports and must be considered as a whole, I also completed the training as a coach with the world's most successful nutrition program, Weight Watchers. The topic of health and exercise is becoming more and more important in our society and in the future it has to become a part of our daily life. For this reason, it is important for me to have well-trained and motivated successors. Because of this I dedicate part of my time to the task of being an expert in the examination of apprentices as well as an expert in the jury of the Swiss Professional Championship in the field of fitness and health.

Hi. Today I want to share with you my experience that I lived with Alain. Since I have a severe autoimmune disease that causes permanent severe pain, it is not easy for me to build and maintain muscles in a targeted manner. When I met Alain I was enthusiastic from the start. He takes the time to listen to my medical history and patiently addresses my goals and wishes. Training with Alain is always challenging and very good. He thinks about exercises that my illness allows. He knows a lot and can explain everything simply. As a result, I have already achieved my personal goal. Thank you Alain for your valuable work. I'm really looking forward to our next training session.
