Just watching the lead-in tape before the overall yoga session, I discovered that I was doing one of the asanas wrong.
In this "asana" she told me to lift my legs to a 45 degree angle. So I lift my legs to a 45 degree angle off the floor and proceed with instructions.
In the pictures, she is lifting her legs to a 45 degree angle on the other side of her body, which is over her head. She's coming from the other end of the axis.
I'd call that a 135 degree angle.
In all, I like it better, the getting up on my shoulders, but we need some agreement about geometry.
