Tennis, or sport in general, has become incredibly professional since my ATP years. Technique, method, the conditional aspects specific to a sport, nutrition, physiotherapy and injury prevention, training and competition planning, mental strength; only when all the systemically relevant factors are correctly "timed" and applied are the prerequisites for a possible career as a tennis professional then created. This beautiful manual supports you in finding the right path for your child or your tennis student. It will also help you to analyse their current level and to make adjustments if necessary. It is an absolute MUST READ for every mother, every father and every coach who is genuinely interested in their tennis-playing child and their best possible development.
