These names do not stand for a result achieved with me. They are expert voices on scientific training. Where someone speaks about our joint work, the quote says so explicitly.

This was the first time I ever held a racket, and I could learn it right away.
Andy is a former regional-coach colleague of my long-time tennis coach. He conducted an interview with me, which will appear in the book 'Faszination Padel', published on 14 October, and has already appeared in a shorter version as a blog post on Padelpoint. As part of the German youth national team, being part of this project means a lot to me, and I am really delighted about it! Since we got to know each other, I have noticed how committed you are to this sport and how much passion you put into the book. Especially for us young players, it is important to become visible and to convey how much fun this sport is. Thank you very much for your support and this wonderful opportunity!
In his coaching work, he distinguished himself through his passionate, competent and motivating manner in passing on his expertise to his players. What stood out to me was his exceptional didactic skill, as well as his positive style of communication.
Expert voices on the method and the book
Established coaches on scientific training and the book 'Faszination Padel' — professional context, not a personal endorsement.
Looking back on my career, I am especially proud of my 55 doubles titles, including winning the French Open and the US Open, and of the time I was world No. 1 in doubles. Those achievements came through hard work and close collaboration with great partners like Pavel Složil and Miloslav Mečíř. Even though talent and stamina were always the foundation, in recent years I have noticed how scientific training methods have changed the sport further. The integration of biomechanical analysis and data-based strategies has helped many players take their game to the next level. It is no miracle cure, but I can only recommend that every ambitious player make use of these developments to get the best out of themselves.
As a padel coach at the highest world level, I have experienced first-hand the importance of scientifically grounded training. Through my work with top players from around the world (currently still on tour), I have seen how the combination of technique, biomechanics and mental preparation lifts the game to a new level. Biomechanical approaches help to optimize movement patterns. Such principles are essential not only for professionals, but for every player who wants to improve their performance. Scientific training offers a clear path to keep making progress and to get the best out of your own potential.
“Training includes, among others, the Toni Nadal Excellence Programme and GPTCA/ISMCA (Alberto Castellani).”

Documented credentials — the hard facts
Toni Nadal Excellence Certificate (2018), issued by World Mastery
Toni Nadal Excellence Certificate (2018), issued by World Mastery — a certificate programme based on Toni Nadal's coaching methodology.
Toni Nadal — uncle and long-time coach of Rafael Nadal, board member of the GPTCA (according to the association).
GPTCA/ISMCA coach training (completed 2019)

An author-reported ranking jump.
German tennis measures competitive level on national rankings. This section describes a move from LK2 to around rank 150 nationally — an author-reported individual case.
A player I worked with individually
author-reported performance case (tournament player)
One player I worked with individually made marked improvements over several years. She moved up to a high national competitive level — and her biggest reported step of all was from LK2 to around rank 150 nationally, an author-reported individual case.
The full account, in the original German:
Eine von mir betreute Spielerin verbesserte sich über mehrere Jahre jeweils sehr auffällig. Sie stieg bis auf ein hohes nationales Wettkampf-Niveau auf, und ihr größter Aufstieg im Sinne der Leistungsentwicklung war von LK2 auf rund Platz 150 der deutschen Rangliste — ein vom Autor berichteter Einzelfall. Ebenso wie bei einem Großteil der anderen auffälligen Spielerentwicklungen war auch hier der Knackpunkt noch vor taktischen Elementen das korrekte Verständnis der Kraftverhältnisse im Treffpunkt. Sie wurde über mehrere Jahre teils durchgängig begleitet, und Teile ihrer Entwicklung wurden auch bei Fachvorträgen dokumentiert. Ihre Spielerentwicklung hat durch die schnelle, anhand des Rankings messbare Steigerung sehr große Aufmerksamkeit erzielt.

What players and partners say.

"We were all delighted by his straightforward, clear way of communicating. On top of that, his immense theoretical knowledge as a sports scientist impressed us — all the more because he translated that theoretical knowledge perfectly into practical exercises for us."
"We have never learned so much from a coach in such a short time as we have from Andy. He immediately recognizes where the flaws in the stroke lie and knows the right solution for every problem — to fix the flaw and improve the player's game."
The chairman of a tennis region, who has organized a well-known Senior ITF tournament in Mallorca for many years: 'Andy is a professionally qualified and competent coach.'
In 2022 my son had the chance to train with Andy, and we are truly happy with the progress he has made. The work on contact-point fundamentals and the force relationships toward the ball at the point of contact helped him a great deal. These techniques and the underlying biomechanical understanding noticeably improved his game. The training in Andalusia and later in Hochkönig was a valuable experience, as were the further training sessions afterwards. He now plays successfully in youth tournaments and in league matches. Andy worked with great patience and dedication, which really motivated him to keep developing.
I am delighted about the publication of Faszination Padel on 14 October and overwhelmed that so many pre-orders have already come in. As an author and journalist, my goal is to keep advancing the sport of padel, and the book is an important step in that direction. I am especially pleased that the training aspect is covered so thoroughly in the book — an area that is decisive for player development.
As a business consultant and padel coach with a background in psychology and business administration, I know how decisive scientific findings are for an athlete's development. The connection between mental strength and sporting performance is often decisive. In padel it is no different — the right balance of mental preparation, physical training and tactical understanding can make the difference. I myself was lucky enough to train with Hernan Flores, who is featured in the new book Faszination Padel, and I experienced first-hand how important sound knowledge is for progress in sport.
The development of the sport of padel is based not only on technique and talent, but also on a deep understanding of scientific principles.
A person from earlier coaching work learned some great biomechanical principles! 'I'm still benefiting from my forehand whip in 2025.'
