This was the first time I ever held a racket, and I could learn it right away. (plus forehand mechanics: I'm still benefiting from my forehand whip in 2025.)

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.

„Fachliche Anerkennung u.a. von Toni Nadal, Tomáš Šmíd, Alberto Castellani (GPTCA), Hernan Flores (World Padel Tour) und Dominic Condrau (Olympia Paris 2024).“

Documented result

LK2 to DTB 150 — documented.

LK2 (the German tennis ranking ladder, level 2 of many) and DTB 150 (rank 150 of the national German ranking — among the country's top 150) are how German tennis measures competitive level. The jump between the two, in six weeks, is what this section documents.

LK2 DTB 150

Julia Wagner

documented performance evidence (tournament player)

Julia had two standout leaps in her tennis career — 2013 to 2015, and again in 2021 to 2022. She moved up from the Bavarian league (Bayernliga) into Germany's second national league — but her biggest jump of all, from LK2 to DTB 150 in only six weeks, is the one that is documented here and was noticed across southern Germany.

Original quote, preserved in full (German):

Julia konnte sich in den Jahren 2013 bis 2015 und in den Jahren 2021 und 2022 jeweils sehr auffällig verbessern. Sie stieg nicht nur z.B. von der Bayernliga in die zweite Bundesliga auf, sondern ihr größter Aufstieg im Sinne der Leistungsentwicklung war nachweislich von LK2 auf DTB 150 in nur 6 Wochen. 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 im Jahr 2013 bis zum Jahr 2015 teils durchgängig begleitet und Teile ihrer Entwicklung wurden auch bei Vorträgen beim Verband deutscher Tennislehrer dokumentiert. Im süddeutschen Raum hat ihre Spielerentwicklung durch die extrem schnelle anhand des Rankings messbare Steigerung sehr große Aufmerksamkeit erzielt.
