Daughter Carrie told me about this very cool and helpful yoga site called doyogawithme.com. It is excellent. They have videos and recordings for all levels with classes, poses, meditations, breathing exercises, tutorials, testimonials, programs, and everything in between. The best part is... it's also FREE!!!
I wouldn't say I am overly into yoga, but I like some of the meditations and relaxation techniques, plus I do several basic moves for stretching. I find that to be very beneficial for me.
So, whether you have trouble sleeping, are stressed out, or simply want to get in better shape... I think this fabulous site is definitely worth checking out.
