In episode 235 of the Functional Tennis Podcast, I sit down with Sandra Zaniewska, coach of WTA Top 20 player Marta Kostyuk. Sandra, a former pro herself with wins over the likes of Ons Jabeur and Ash Barty, transitioned into coaching at a young age and has since worked with top names like Petra Martic and Alizé Cornet. Sandra shares her journey from player to coach, her experiences leading the development of high-performance players at the Mouratoglou Tennis Academy, and her role with the Champ'Seed Foundation. We dive deep into the dynamics of coaching, exploring key themes like respect, communication, and trust. Plus, we tackle the big question: who’s really in charge—player or coach? I hope you enjoy this insightful conversation! Fabio This podcast is sponsored by ASICS.
