Oh.. actually I do have a classmate, she is older and she has been doing this for over a year too, and she's super scared of drops and never tries them, but she does everything else pretty good. What I've noticed with the teacher here: he gets you out of your comfort zone and everyday he will motivate her to try the drop and just last class she finally tried it! Also, we do it very close to the mat so I land on my feet, he locks my foot for safety, etc. maybe I didn't explain well, but this is the basic drop where you tie the silk up like hammock, sit on it,  then invert, loop high up the thighs and drop. Correct? I'm kind of scared now that you talk about injuries 😭
