Mental strength in competitive sports is not a coincidence, but rather the result of training and experience. Therefore, just as in physical training, mental training should begin at the student and youth level. In the long term, it leads to greater self-confidence, more stable competition performances, and particularly helps so-called training champions to deliver their performance when it matters. This book is aimed at coaches and sports psychologists who wish to plan and conduct mental training with athletes in individual coaching or group settings. For each topic area, exercises of varying difficulty levels are presented, allowing both beginners and experienced athletes from various sports to benefit. Accompanying materials are provided in the form of guides, worksheets, and handouts as printable templates.
