I have been doing at home yoga and relaxation videos for a couple years, what I do is look on amazon for workout
dvds, then get them through interlibrary loan to try them out for free
before I buy them, going to do the same with preg fitness vids. Waiting for Ina May's Guide to Childbirth book to come in now, heard it is great book. I recently bought the Prenatal Yoga Deck, it has breathing techniques and poses, I like it because you can go as many cards as you have time for.
