I've only done yoga a handful of times, do you know much about it?
I have never really done it, I have tried to meditate. I know it originated in ancient india though, and I know sort of what they do
I think it was part of my PE class in high school.  I remember very little!  What do they do?
in indian tradition, it is less physical, and more a combination of spiritual refletion, and meditative state. Of course, there is still some stretching and holding exercises
