I just have to get my praise in for yoga, too. I have been practicing yoga, on and off, since I was in high school. About 4 years ago, I was experiencing debilitating migranes. Yoga was the answer for me.

I go to a yoga class twice a week and fit in a dvd in between. Please, don't try to learn it on your own, go to a good class with a good instructor.

How do you know a good class and instructor? The class will be small (15 at the most - the class I take is 5) and the instructor will walk around during the class making adjustments, helping individuals. In addition, a great teacher will ask you about your body and physical health. They will find poses for you that work for you and modify all poses to work with your body.
