I disagree with the reviewer who says this dvd is dull. I have liked it specifically because of its simplicity. There is no music, but this is great because there is no chance of getting bored of new age music on a loop and I have been able to do the yoga to either whatever soundtrack i choose or to no music at all so that i can focus on my breathing which i found a useful tool during contractions in my previous two labours. The yoga, as you would expect of pregnancy yoga, is relatively gentle (though i find session 3 a proper workout) but it definately helps. Even though i only manage a session once, maybe twice a week, i can feel my back strengthened and always sleep amazingly well afterwards. This is my 3rd pregnancy and so I have tried other yoga dvd's but think that this one stands head and shoulders above the rest. I would really recommend this dvd and have been telling my pregnant friends to buy it.
