First picture: I was so sure that my feet were parallel. The picture proved something else. I wouldn't mind if I dropped back, but these are exercises to drop back correctly. Good that I saw the position and I could correct it (see second picture).
Speed: In India we held the arms crossed in front of the chest, with one exhaling we went back and with the next inhaling we went up. So it is when dropping back, exhaling down, inhaling up. The self-timer does not give me more time, I must do it so fast.
Back bending felt good today. A long way down is still true.
