Sports practice has been part of my daily life since I was very young. I am passionate about artistic gymnastics which I practiced for 12 years in competition. I discovered CrossFit in 2012 and have been practicing it at a high level ever since.

After more than 10 years spent in a large company in the industrial sector, it was my passion for CrossFit that pushed me to change my professional orientation in 2015 to dedicate myself to teaching it and supporting you towards your goals!
I hold a BPJEPS, I then continued to train and improve myself to be sure to bring you the best at all times: 1st woman certified CrossFit Level 3 in France, nutrition coach (Precision Nutrition Level 1), Adaptive & Inclusive Trainer (AIT), Certified in Movement Assessment (Active Life Professional) to name only the most important...
My experience has allowed me to work with different client profiles. My mission is to accompany people to ensure that they feel motivated and involved at all times, whatever their goals or the challenges they face on a daily basis.

Happy Beach Trip


I'm Antoine Cayroche!
I have been involved in CrossFit since 2012.
I have a passion for anything that makes you stronger, because as Louis Simmons says “weak things break”, so I love lifting weights in all forms!
To me CrossFit is like the known universe, ever expanding and all part of it. CrossFit is for everyone, all inclusive and I love helping people do things they never thought they could do.
Today in my practice I am looking for 2 things; the first, is to enjoy the training. Discovering, trying, failing, succeeding, or even simply pleasure to move, to sweat and to be human in its physical and physiological dimension because today we are beings endowed with intelligence who for many have forgotten that our body is not just for us to go from bed to office then on the couch.
The second is to learn; to learn about yourself, to experiment with things that I would like to implement in my lessons and coaching, to make mistakes to try to make those I coach avoid them, to find solutions and to discover new or rediscover new ideas.
My practice has helped me to increase my self-confidence and to believe in what my body is capable of and that is more than precious and essential to the human being I think to be happy.  As Socrates says: “No man has the right to be an amateur in the matter of physical training. It is a shame for a man to grow old without seeing the beauty and strength of which his body is capable. (also valid for women!)
And of course, all the encounters that fill my heart.
