Transforming my body and life in the past few years wasn’t easy work - it took a lot of perseverance. 35kg body fat loss would have been impossible without the right knowledge and attitude. Learning from the best with the GPNi® and the ISSN certification I highly recommend anyone looking to improve their lives for the better.

Over the past few years, my interest in sports and nutrition grew, while the different concepts and opinions seemed confusing. The SNS course was a challenge for me, as I have no prior educational background on this topic, but professional teaching, a well- structured outline and access to the latest science information connected all aspects to a coherent picture of sports nutrition.
