How Many Hours Should Junior Tennis Players Train? Piotr Sierzputowski

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.

We also get into the latest from Head, Dunlop and Tecnifibre, why some pros switch back to their old rackets, and the balance between power, spin, control and comfort. Plus, Jonas talks about his Toroline string collaboration and reveals the racket he’d reach for with a big match on the line. Plenty of racket chat to help you weigh up your next switch or appreciate what’s already in your bag.

25 Years of the HEAD iPrestige: Bringing a Classic Back with Max Defregger

What makes the HEAD Prestige so special, and where does it fit in today’s game? I am joined by Max Defregger, HEAD’s Global Business Unit Manager for Tennis Rackets, Bags and Accessories, to celebrate 25 years of the iPrestige and explore the two rackets marking the occasion: the iPrestige MP 2.0 and the Prestige Limited. Max takes us behind the scenes of bringing a classic back, explaining what HEAD wanted to preserve from the original and how the more forgiving Prestige Limited offers a modern interpretation of that familiar feel. We discuss: The iPrestige’s memorable 2001 season, including Goran Ivanišević’s Wimbledon triumph. The differences between the two new rackets and who each is designed for. Racket development, molds and professional player customisation. Why Prestige still has a place in an era of power and topspin. A hint of what HEAD has planned for the Prestige’s 40th anniversary in 2027. Whether you grew up playing with a Prestige or are curious about its loyal following, this episode explores the appeal of one of tennis’s most recognisable racket lines.

Luciano Darderi on Reaching the ATP Top 20

While at the Italian Open in Rome with ASICS, I got the chance to sit down with Luciano Darderi for this mini episode of the Functional Tennis Podcast. Luciano talks about growing up between Argentina and Italy, being coached by his dad, and why his family sacrificed so much to help him pursue professional tennis. He also shares what changed as he climbed the rankings, what separates the very best players from the rest, and what it actually feels like practising and competing against players like Jannik Sinner and Carlos Alcaraz.

I Tried Something New… (My First YouTube Video Is Live)

I tried something new. For a long time, I’ve talked about starting a YouTube channel where I get back on court and test myself against players better than me. The reality is, I never really had the time to do it properly. Now I’ve finally started. In this first video, I take on one of Ireland’s best players, Sinead Lohan, to see how I stack up and to explore the level difference.

Does the Saber Improve Your Tennis? Here’s What the Data Shows

Over the past 12 months, I’ve been working with biomechanics researcher Dr Nick Busuttil to better understand one simple question… Does the Functional Tennis Saber actually improve your game? In this episode, we dive into the findings from that research and what really happens when players train with a constraint racket. We discuss how the Saber influences stroke mechanics, why players may initially feel less accurate, and how that “useful struggle” can actually help build better timing, contact awareness and more consistent strokes over time. Nick also explains why tools like the Saber can promote adaptability in your game, act as a circuit breaker in training, and how coaches and players can use it effectively in practice and warm ups. If you’ve ever wondered whether training aids actually work or if they’re just gimmicks, this episode will give you a clear, science backed perspective. You can download the full research report here. And if you have any questions after listening, feel free to reach out to me on Instagram here or you can email me here. I hope you enjoy the episode.
