I have been practicing with yogaglo.com lately because I haven't made as much time to get to the studio to practice. I really enjoy YogaGlo, even though I believe it is much better to practice with a teacher who can enhance your poses or teach you things you can't learn in a podcast.
I really encourage people to get yoga where they can, and not insist on studio or bust. In our modern lives we have so many things going on that we need to fit yoga in where we can and not chastise ourselves for not attending a studio class every day.
Do what you can. All is coming.
