If you are a beginner in doing yoga, it is very much ideal
to enroll in a yoga class first. It is for you to gain more knowledge about
this exercise and know the proper way on how to do it. You can have yoga DVDs
too which will serve as your guide for doing it.

In an ideal world, all yoga instructors in classes pay full attention to every student to make sure everyone is doing things appropriately. Unfortunately, my point is that in the real world, many instructors in many classes (that I have personally attended and that friends of mine have attended) have not been so attentive, and so I know many people who have been injured, sometimes quite seriously, as a result. That is my warning.
