If you are thinking of learning yoga. I highly recommend this app. You can download it free on your phone. It is called Down Dog. You are able to choose your level, type of yoga you want to try, length of time for your workout, and length of time for Savasana. "My favorite part of yoga". Music plays in the background, and you can take it with you anywhere.
It is perfect for trying yoga in the privacy of your own home. I love it. I try to work yoga into my routine about four days a week now.
