I truly don;t expect them to remember all that, fully expecting that I'll remind them during the practice, and they'll remember our very brief conversation. Surprisingly, they remember more than I expect. They then help me adjust accordingly.
I'm lucky - we have some great instructors around here who put a lot of thought into their classes.
I've found that if I can bring some focus to my breath, most all my poses benefit greatly as I can decide what to relax and what to strengthen.
Good Instructors come from great teaching instructors, and aware students come from good instructors.
BTW, I'm not an instructor, by a long shot - just slowly becoming a better student.
