Fit · Fun · Focus makes visible why someone plays and how they grow.
One practical system to help players, coaches, parents, clubs and events develop further through tennis and sport.
The 359 Method makes tennis development visible: Fit for energy and movement, Fun for enjoyment and connection, Focus for attention, learning and progress. We believe in progress. Not perfection. That is why we are 359 and not 360 degrees: perfection is never the goal. There is always room for improvement, growth and progress. For us, tennis is not just a sport — it is a powerful vehicle to develop people physically, socially and mentally.
Whether you come to stay fit, for enjoyment and the people, or to genuinely grow in your game — every session at 359 is built around three pillars: Fit, Fun and Focus. Recreational or ambitious, you set the goal — we build the route.
- Fit stands for energy, body, movement and load capacity.
- Fun stands for motivation, connection, confidence and enjoyment.
- Focus stands for attention, learning goals, discipline and progress.
Our coaches work with the same development language, so every session contributes to progress — for the player and the person behind the player.

Application of Fit · Fun · Focus
Collaboration as a system — several coaches around one player
At 359.tennis you never face one coach. You have a team.
At many tennis schools a player gets one fixed coach and stays with that coach for years. We deliberately do it differently. At 359.tennis several coaches work together around every player — a multidisciplinary team that meets, observes and adjusts.




Why this works better — for the player
- ·More perspective. Different coaches notice different things. What one misses, another sees.
- ·No dependency. A player never has to stop or start over when one coach leaves.
- ·One method, several voices. Coaches work from Fit · Fun · Focus™ — the approach stays consistent, even when the coach changes.
- ·Faster development. What a player practises on Monday is known by the coach on Thursday — no knowledge gap.
Why this works better — for the coach
Coaches who work alone develop more slowly. At 359.tennis coaches learn from each other: in weekly reviews, by observing colleagues, and by building the method together.
Learning from each other
Weekly reviews about players and approach.
Stronger together
A team knows more than one person ever can.
Continuous growth
Coaches keep developing within the system.
One coach is a person. A team is a system.
That is why the 359 Method is not one coach's approach — it is how our whole team works.
Your pathway from Start to Perform
Everyone starts from a different point and has a different goal. That is why 359 works with four clear programmes. Choose the training format that suits you now and expand later when you want to train more or work more purposefully on your development.
- start
Start — Begin playing tennis
An accessible starting point for players who want to discover tennis, build confidence and learn the basics.
- core
Core — Develop consistently
Train regularly with attention to movement, enjoyment, technique and play.
- plus
Plus — More rhythm, more progress
For players who want to train more often and create greater continuity in their development.
- perform
Perform — Train with greater purpose and intensity
An appropriate combination of group lessons and private or duo training for players who want to get more from their development.
Directional, not mandatory
The steps are directional, not mandatory. Choose the programme that fits your age, experience, goals, availability and training needs. You do not need to follow every step.
What you can expect in every programme
- Start at the level that suits you
- Expand later when you want to train more
- Combine group training with private or duo lessons
- Work with clear goals and feedback
- Keep Fit · Fun · Focus in balance
- Make progress visible
Fit · Fun · Focus in balance
Every programme keeps Fit, Fun and Focus in balance. The intensity may change, but movement, enjoyment and purposeful learning remain part of sustainable progress.

Proven at the ABN AMRO OPEN
The 359 clinic concept was developed and refined at the ABN AMRO OPEN. 8 days, a new group every 30 minutes. From 10 to 120 participants per session. That demands structure, simplicity, and a system that always works.
