"The strongest athlete I have ever trained. Monstrous.": Panichi’s 6-month plan to rebuild Holger Rune

Marco Panichi has spent decades sculpting the bodies of tennis royalty, from the elastic resilience of Novak Djokovic to the development of Jannik Sinner. Now, the veteran physical trainer faces perhaps his most explosive challenge yet in Holger Rune. The partnership began with high hopes but hit an immediate hurdle when the young Dane suffered a significant tendon injury. However, Panichi views this forced hiatus not as a setback, but as a critical opportunity to recalibrate a Ferrari that was being driven off-road.

The Dane suffered a fall in the middle of the Stockholm Open semi-finals that forced him to miss the final stretch of the season. The Achilles tendon rupture was initially expected to require between 9 and 12 months of recovery, and it would not have been surprising if he missed the entire 2026 season. However, Panichi believes that Rune’s return could come much sooner than anticipated.

The immediate focus has shifted entirely to rehabilitation, with a timeline that demands patience in a sport addicted to speed. Panichi and the medical team are looking at a six-month window for a full return, a period necessary to ensure the injury heals completely without the risk of relapse.

The strategy involves a meticulous pre-athletic phase followed by specialized treatment in Doha, distancing the player from the daily grind of the tour. This pause allows the team to reset the physical foundation of a player who has often relied on raw talent over structural stability.

The physical raw material, according to Panichi, is simply unprecedented in his long career. Having worked with the greatest movers in history, his assessment of Rune’s natural gifts carries significant weight in the tennis world. He describes the Dane’s explosive power as "monstrous," placing him in a unique category of athleticism. The goal now is to harness that raw power into a disciplined, sustainable game style that can challenge the current hierarchy of Jannik Sinner and Carlos Alcaraz.

The nature of Rune’s injury—a total tendon rupture—requires a conservative approach that prioritizes long-term health over short-term ranking points. Panichi is keenly aware that rushing back could be catastrophic for an athlete who relies so heavily on explosive movement. The team is currently weighing the risks of surface transitions, with the grass season potentially being a casualty of this cautious timeline.

"We absolutely do not want to rush because we know it is better to be cautious a little bit more to then forget about what happened. I believe for us too, the timeline is more or less that: 6 months. I believe it is more appropriate to wait for the hard courts and not play immediately on grass, but we will see during the process what happens. We leave the door open enough, we will evaluate together with the doctors and the whole staff what to do."

Panichi’s comparison of Rune to his former charges and current rivals is fascinating. He sees the Dane not as a copy of the existing stars, but as a unique hybrid with physical tools that might even exceed those of the legends he has trained before. The challenge lies not in creating power, but in controlling it.

"I believe he is a player a bit more complete, a middle ground between Djokovic, Sinner, and Alcaraz. We are in that range. I knew him as a great athlete, and now training him I have proof: He is the strongest athlete I have ever trained in terms of explosive force expressions. Monstrous. But he doesn't put this athlete on the court at the right moments yet. He needs to balance this mind-body system. It's a challenge, but I am confident."

Perhaps the most revealing insight from Panichi is the dismantling of Rune’s public persona. While fans see a reactive, emotional player, Panichi sees a thinker who needs to learn how to trust his instincts in the right way, creating a "game identity" that isn't currently there. "I found a guy who has a very, very high introspective capacity. This is very positive," he said. "He is a guy who, contrary to what it seems on the court, thinks a lot. He doesn't do it on the court actually, but outside he does. So we can work on this."

"He is not completely instinctive like other players I trained. When I started, we aimed at creating a game identity that is his. He has talent, he can touch the ball delicately or hit hard. But this puzzle was messy. In moments to be solid, he wasn't; when he had to dare, he became conservative."
