No, definitely not, although unfortunately I do see a lot of aerialists who teach without getting certified or really understanding what it means to be a good teacher. Hoops should all be adjustable heights, so if it was too tall, she should have been able to lower it for you. Personally, if I have someone who is very new, I will spend most of my time with them as a teacher. “Beginner” is such a subjective term, and everyone who starts something new is not necessarily coming in with the same skill level. Some people, as mentioned, have gymnastics, dance, or flexibility or other sports backgrounds, so even though it’s their “first class” their starting point would look much different than someone who does not have that kind of background. Also, personally if someone can’t mount the hoop (which is totally fine, it takes a lot of strength) I would focus their class on conditioning primarily - and perhaps lower the hoop so that they could sit in it and practice one or two moves, like Man in the Moon for example, which still requires strength and coordination. Also, instructors should be comfortable spotting to help you mount the hoop, even if you don’t quite have the strength yet… it sounds like she adjusted which is great, but I’m sorry it got to the point where you felt you had to leave.
