I want to start doing pilates but have a 9 month old DD and a husband who gets in from work no earlier around 7.30- 8pm most evenings so it's difficult for me to get to a class. I have tried a couple of different books and dvds but find it difficult to know whether I'm doing the exercises correctly. It seems to be one of those exercise types where form is particular crucial. Do you think it's possible to learn pilates by yourself or do I realistically need to resign myself to somehow trying to get to a class?
