I’ve read and heard musician’s refer to playing a musical instrument as athletics on a smaller scale.
This is actually a pretty accurate appraisal and one that is worthwhile evaluating.
Playing the banjo is more than just using your fingers. No matter what style of banjo playing, there are physical considerations that can be helpful in fostering a healthy approach to your banjo. Because no two people are alike in the way they walk, talk, dance, sing, run, stand, sit, swim, play tennis etc, we must allow for a huge range of tolerance to allow individuals to find their own personal comfort zone. The suggestions here are not meant as “absolute” or “iron clad” or “cast in stone.”
These are mere guidelines that might aid in facilitating greater comfort while playing.
