Random Notes

Here is a lengthy floor barre routine I found online. It looks pretty intense.

I just read that in arabesques, the shoulders are actually supposed to be squared (as opposed to moving the arms?):

She's not holding her left arm behind her; her shoulders are rotated and squared!

Also, for some reason my left hip area up through my torso is very tight. When I cross my right leg over my left, it feels fine but when it's my left leg over my right, it sends an ache from my hips up. I also feel this when working on splits.
