I bought three Yoga tapes for pregnancy - this was the only one I could stand doing. I was a daily yoga practitioner before I got pregnant, and then became a weekly class goer after I got pregnant, so I bought this tape to maintain my abilities. I found the discussion helpful and the poses were very good for me. They helped me work on flexibility (one can always hold longer than the video by using the pause button) and the routine was quite nice. I thought this one was much better than the Crunch Yoga Mamma (do not buy) and the Prenatal Yoga by Shiva Rea (which I did not enjoy).
I am honestly surprised at all the bad reviews of this video. I am 6 months pregnant and have been having some low back pain. I started to feel relief immediately after using the video one time (I now use it at least 3 times a week). Yes the DVD is a little old and his accent is kind of funny, but it really has helped me relieve stress and feel calmer. I always love how I feel after doing this yoga DVD. I like how he focuses on doing the poses in the correct form, because it is the MOST important part of yoga. This is not for someone looking for a tough workout, this is for someone looking to strech your body, relax and relieve some pressures brought on by pregnancy.
We own another Yoga Zone DVD, and it is great, so naturally I bought this one when my wife got pregnant. This is NOT the same format as the other Yoga Zone DVD. It is a guy (and his 8-month pregnant wife as a model) advising you the different positions. There is no background music, and the poses are held for long periods of time while the guy explains correct form. We were not interested in "performing" or getting the forms exactly right, but rather light exercise that was safe and easy to do. This video is more for someone with extensive Yoga experience.
I got this DVD at the beginning of my 1st pregnancy and used it quite often through all of them. It really helped with my sore back and legs, was an easy work-out when I didn't have the energy to really work out hard, and the relaxation part at the end left me so relaxed, I sometimes fell asleep while doing it. I ordered a second DVD for a friend, whom I had let borrow the DVD during one of her pregnancies (and also LOVED it), then she became pregnant again at the same time I was, and I didn't want to part with it. While I still do arobic pregnancy workouts often, on days when I'm feeling sore or just need a light, relaxing workout, I still use this one.
