How much time should your child spend on court and when does more practice stop helping?Coach Piotr Sierzputowski returns to the Functional Tennis Podcast to discuss one of the questions I hear most often from parents. Focusing on players aged 16–18, we explore his approach to training hours, why the quality of each session matters, and why adding more practice isn’t always the answer.We chat about group versus individual training, balancing tennis with fitness and school, and recognising when a player needs more recovery. We also catch up on his coaching journey and the lessons he’s learned working across the women’s and men’s tours.A conversation for parents, coaches and players trying to find the right balance between working hard and staying fresh.
