What is taken for granted by athletes, namely targeted movement and strength training beyond the practice of their actual sport, is often neglected by many musicians. It is only when complaints arise, whether in the form of tension, overexertion, or pain, that they realize the high demands they place on their musculoskeletal system. This book is aimed at active instrumentalists, regardless of their skill level. It offers solutions for those who want to improve their endurance and performance on their instrument, prevent future problems, suffer from discomfort while playing, or seek a balance to one-sided posture. The focus of the book is on practical exercises, but theoretical foundations are also addressed. The book aims to help musicians prepare more specifically for the physical demands of playing music. It seeks to motivate.
