It is common for athletes to stretch before and after exercise in order to reduce injury and increase performance, but why as musicians that use the same muscle groups generally not stretching? Playing a bowed-string instrument such as the violin requires complete freedom as it uses nearly all of the muscles in the upper body to be played. There are 6 basic upper body muscle groups that need stretching which are the neck, back, shoulders, arms (bicep & tricep), and most notably the wrist, and fingers are needed to keep those muscle groups loose.
