Yellow Ball (Ages 11-18)

Mastering the Game with Advanced Training

The Yellow Ball program is designed for our teenagers and advanced junior players. At InsideOut Tennis Academy—serving families in Zurich, Schlieren, Urdorf, Kilchberg, and Wädenswil—we focus on the transition to the standard tennis ball, emphasizing power, precision, and tactical maturity.

​

InsideOut Tennis Academy relies on the kids tennis program created by ITF (International Tennis Federation) “Play and Stay” and Swiss Tennis. We are balancing between technical, tactical and coordination training, and points play to experience the joy for the game. At this level, we refine individual playing styles and prepare students for competitive match play or lifelong recreational enjoyment.

​

Seasonal Training and Spontaneous Sessions

Supported by our dedicated development team, we ensure every teenager finds the right balance between challenge and success. Usually, the kids' sessions run on a seasonal basis (including a 10% discount on the total price), once per week for 1 hour in a group of 3 or a group of 4 players.

​

It is possible to organize spontaneous trainings depending on the availability and the level of the players, and in this case, our normal price list applies without the discount.

​

Costs: the full price list is available here.

• Kids camp during school holidays.

• Entry is possible at any time.

• Price is per player per hour including the coach, court rent, and equipment.
