Thank you, Deborah!
I use the wall for handstand too. I can usually get one leg away, but have not tried to do it without the wall at all. Okay - once i did - but i had a spotter.
Getting a good alignment for 30 seconds of tripod headstand sounds awesome. I can get up into that but have no idea if my alignment is correct. And I never time how long to hold things. That is a good idea.
My growth right now is a bit stymied because I don't really have a wall in here in the RV. I have to screw around to have room to do anything, really, and mess with chair backs and such.
