« Avec l'entraînement de JS Synergy, je suis plus concentré dans les combats, donc mentalement plus fort. Physiquement, j'ai plus d'énergie car cet entraînement fonctionnel s'adapte à mes attentes pour mes combats. Junior a une vision globale du sportif et cela me convient parfaitement car faire la différence sur mon adversaire en combat commence à l'entraînement pendant la préparation physique et mentale. »

- Doudou N'Gumbu – Professional Boxer

« I was looking for a method that contains both the physical and psychological aspects : while applying synergy, both my body and mind come together and I have noticed an improvement of my overall state despite my age (66 years old). Synergy fulfilled my expectations because during each session, we have an exclusive exchange that allows me to reach my goals, one session at a time. I have a better approach concerning my body and mind and a total understanding of my body through this holistic approach.»

- Benjamin Alcacebe - Pro Rugby D2

« Ever since i have started using synergy in addition to my training sessions at Bourgoin and my return from a serious injury, i now have the essential tools to get back to my best. The improvement of my performances on the field goes hand in hand with a stronger state of mind. I now have the useful tools for my life as an athlete and also off the field. I recommend for the athletes who are looking for an additional activity, given that this goes beyond sport »

- Marine Exposito – Hair salon owner

« With JS Synergy training sessions, I am more focused during my fights, which makes me mentally stronger. Physically speaking, I have more energy as this functional training is applicable to my needs during fights. Junior has a clear vision and this works for me because gaining an advantage on my opponent starts during training while working on my body and mind.
