I did another hour yoga session on my own. Yoga 3 days in a row is a little much, but I wanted to play around more. It helps that the intensity is a little lower without someone pushing me along. I gave the transition between low plank and up dog a few more tries, but I still cannot do it correctly. I think it is unlikely upper body strength is holding me back (most of the women in my class do it easily), so I need to figure out what the form problem is. Hopefully I can work it out with my teacher during the Thursday lesson.
Otherwise, I was just happy I found the motivation to do this again. My schedule will allow me to return to normal classes pretty soon. If I get to bed early enough on Thursday, I'll attend the Friday 7:15am class.
