Part of the problem, Sririam, is I don't like to go out much. In fact, I like to go out very little.
Well, that is progress! In the past I would have said, "I can't go out".
So no going to yoga classes for me. I have restarted Pilates, have had six sessions I think. That is sufficient for the time being.
Honestly, the video doesn't show anything unexpected or dangerous, it is fairly basic, Sririam, otherwise I wouldn't contemplate doing it. I'm far too much of a coward, even thinking about some things sends me into a panic or else causes anxiety and terrible fear (I'm a wuss).
Apart from that, I've never really been able to do anything like that, my mind wanders too much or I go off to sleep (sometimes very nice), so if I try this, it may have the same result. If my mind wanders into pleasant thoughts which send me to sleep I will not complain.
Thanks for your concern.
