I know there are several different kinds
of yoga, ranging from what I do, which
is slow and deliberate to another type that
is very physical. Each kind of yoga has its own name and no, I don't know them all. I have read that some people try them all and never do find one they like and some people, like me, find one they like and stick with it. Some people prefer to get into a class because they like the "group" aspect. Personally, I prefer to do it in the privacy of my home.
