At the age of 22, as I was a high level runner and cross skier, I decided to dedicate my life to the science of training to liberate time and avoid sport burn out, thanks to an individualised physiological training program. I became associate professor at the age of 28, and 7 years later became a full professor, allowing me to create the INSERM lab. I now have a start up for paying more researchers and to validate this new way of intelligent training. I hope to have contributed to that, and to have formed a generation of trainers aware enough to progress through all their life with the humility and the curiosity of improving their knowledge for enforcing their field experience.
