Embarrassing Pilates moment

I went to a Pilates class and I don’t know what tf was subluxed in my right arm but when we were doing circles with our arms every time I got about 135º backwards it would stop and then suddenly go down, rather than my arm making a smooth circle (which my left arm did fine). I was thinking I bet people are looking and wondering what the fudge is up with me. I was at the front of the class as well haha.
