Yoga Journal has a great website with all kinds of resources from yoga videos, to articles on yoga history, poses, meditation and more. Under the Newsletter sign-up column you can sign-up for daily/weekly newsletters on various subject.
Check out the Office Yoga newsletter. It is 15 daily newsletters with short videos that describe easy yoga poses and breathing. Those in my Chair Yoga class will recognize most of the poses. These poses are great to do at home or anywhere. If you have a friend who says "oh I can't do yoga" show him or her these videos so they can see how easy it is.
Let me know what you think of the Office Yoga newsletter.
I enjoy yoga as it brings peace to my life. Teaching yoga has brought joy to my life and given me a chance to encourage others in learning yoga.
