Great tips!! Adding/emphasizing one– Remembering that you are ‘the expert’.
Not in an egotistical way, but in a ‘people listen to you when you truly act like you know what you are talking about’ way!
Would you sooner listen to a confident, warm teacher, or one who quietly ‘suggests’ an exercise rather than instructs it, perhaps saying something like “You’ve probably done this before, but…” or “Sorry if you know this already” etc. If someone speaks with a mix of authority and kindness, I listen!
Best of luck to you!!
