I've done it twice now, and I think I will continue for a while. it's cool. I do feel ery well stretched out at the end of a session, and very drained, like it is work. mentally resttive, to some extent. I am surprised by the age - most of the people (in my place) are over 40, and not really hot, but I guess that isn't a bad thing. it involves a little more holding positions in strenous poses than I expected.
