Yoga was part of our curriculum back in high school. In fact, we combined it with basic gymnastics, doing Yoga poses on the balance beam. I was still pretty much flexible at that age and I can do most everything, except the head stand. We didn't do that anymore.
I wonder if I could go back to that practice. Maybe...because some people start to learn in the adult years, and having tried that before, at least I know what to expect. I probably don't even need to enroll in a class, as there are a lot of videos online to learn from.
