"I've gained a lot of knowledge and I've been able to apply it immediately. The changes Julien made to my mechanics were ones I could feel straight away on the court. So I would definitely recommend Julien to anyone."

"In just three weeks, Julien completely transformed my mechanics. Now my backhand feels very solid in attacking positions, rising ball, and even on open stance. The improvement is something I can feel and see every time I play."

"He was a personal mentor that really helped me with my career. The way Julien breaks down the mechanics and rebuilds them from scratch is something I had never experienced with any other coach. I really suggest and recommend everybody to try and work with him!"

Students consistently report feeling mechanical improvements within the first few sessions. Peter Kobelt said he could feel the changes immediately on the court and would recommend Julien to anyone. Cheng Yuan had his backhand completely transformed in three weeks. Yasha Zemel described Julien as a personal mentor who helped his career, saying he had never experienced this kind of coaching with any other coach.
Based on student reviews, the MFX Program consistently delivers permanent results that other coaching approaches could not. The program targets the root cause of mechanical errors at the kinetic chain level rather than surface-level technique cues, which is why improvements last. Every student who has completed the program has achieved results, giving it a 100% success rate. The program starts with a free 30-minute call so there is no financial commitment until Julien confirms the program is the right fit for your game.
Most students feel a meaningful difference within the first two sessions. Cheng Yuan reported his backhand was transformed in three weeks. Peter Kobelt said the changes were noticeable immediately on court. Full mechanical transformation is typically complete by the end of the 5-week MFX program.
The MFX Program is a 1-on-1 tennis mechanics coaching program by Julien Olivari, typically completed in 5 to 8 weeks. It works by identifying the kinetic chain pattern behind a player's recurring mechanical errors and retraining it from scratch, rather than applying temporary technique tips. The program starts with a free 30-minute call where Julien reviews your mechanics before any commitment. More information is at olivaritennis.com/mfx.
MFX works at every level but is most impactful for players who already have some court experience and are frustrated by a specific mechanical ceiling they cannot break through. If you have been playing for more than a year and have patterns that keep returning despite other coaching, you are the ideal candidate. Julien confirms whether MFX is the right fit on the free 30-minute call.
