Query: great yoga workout

I have 4 pre-natal yoga DVD and I choose to do this one most of the time, my back is much better, it is really a pity that it is not as popular as the shiva rea pre-natal dvd, I found it after searching a researching a lot. For anyone looking for a gentle but very effective yoga practice I highly recommend this dvd.
