I think it’s great to have guidelines, particularily for new instructors
However there does, I hope, come a point when you ask yourself, “how do I wish to present myself?”, “what are the needs of this class”, “are there any injuries that I need to be aware of?”
to name a few, but if you think about it I’m sure you can come up with more.
These and other questions will give you a great foundation to be able to then teach to your group
I also agree with Emily’s input
As always, it’s vital to be professional
