    The 359 Development System is a holistic development methodology and the framework behind 359.tennis. It consists of four pillars: Development System (Fit · Fun · Focus™), Progress System, Coach System, and Parent System. This development model for children, juniors and adults was developed by founder Roland Laurense and is applied at NTC Amstelveen, near Amsterdam.

    Looking for a holistic tennis methodology that goes beyond technique? The 359 Development System is an evidence-based tennis development model for children, juniors and adults. With the Fit · Fun · Focus™ pillars we combine physical, mental and personal growth in one integrated framework — from the first lesson to competition level. This player development model for tennis is applied by all 359.tennis coaches at NTC Amstelveen, near Amsterdam.

    The method was developed on court — through thousands of lessons, players and real development journeys. Our goal is simple: to develop better tennis players and stronger people.

    Tennis is the vehicle. Development is the goal. As a player and as a person.

    The core

    Fit · Fun · Focus

    All training at 359.tennis is built around three essential elements.

    FIT

    Body

    Physical development, motor skills, coordination and energy. A strong and energetic body is the foundation for moving more freely, playing better and enjoying the game more.

    FUN

    Heart

    Enjoyment, motivation, connection and teamwork. Sport only truly works when people feel safe, enjoy themselves and want to keep coming back.

    FOCUS

    Mind

    Attention, concentration, decision-making, analysis and reflection. Mental skills that help you on court — and beyond.

    Together these elements create the environment where real development can happen.

    In practice

    How a coach works within the 359 Method

    Every session has one tennis theme and one personal theme. The coach reads the player type — fit, fun or focus — and adapts the exercise without losing the structure.

    • Fit player — gets extra movement and rhythm to channel energy productively.

    • Fun player — gets game forms and variation to sustain motivation through technical work.

    • Focus player — gets sharper decision moments and tactical questions to deepen concentration.

    Philosophy

    Why The 359 Method exists

    Many sports programmes focus solely on technical training and match results. But real, lasting growth requires more.

    Development is a long-term process. It is not just about improving strokes, but about building confidence, perseverance and the ability to learn.

    The 359 Method focuses on the complete development environment around the player — training, guidance, progress and collaboration with parents.

    Balance

    The balance behind the method

    Every exercise, every lesson and every training programme at 359.tennis is designed to balance Fit, Fun and Focus.

    When one of these elements is missing, development slows down. Too much pressure without enjoyment leads to loss of motivation. Too much fun without structure limits growth.

    The role of the coach is to continuously adjust this balance for every player. This is what makes The 359 Method dynamic and player-centred.

    FIT

    FUN

    FOCUS

    The coach adjusts the balance for every player.

    Individual

    Every player develops differently

    Some players are driven by challenge. Others by enjoyment, improvement or connection. Great coaching means understanding the player and adapting the training environment accordingly.

    The 359 Method therefore focuses not only on tennis skills, but also on the person behind the player.

    Connecting to personal motivation
    Adapting coaching per individual
    Growth as a person and as a player

    As a family, we've been playing tennis with great enjoyment at 359.tennis for years. Two of our children follow the Academy and KNLTB Intake program, two are in the regular kids and juniors lessons. We also take group and private lessons ourselves. The training sessions are energetic, professional, and keep us feeling fit and vital.

    Academy & Kids — ontwikkeling op elk niveau

    We organised a corporate sports day at 359 for 60 colleagues. The team handled everything from catering coordination to grouping people by skill level. Even colleagues who had never held a racket had a fantastic time. The feedback was overwhelmingly positive.

    We started at 359.tennis as complete beginners. We wanted to learn tennis and have a regular weekly family activity. Now we take family group lessons together, and our daughter also trains in her own group. The best part is that it's not just a fun sport, but it truly strengthens our family bond.
