I love Pilates. I don't recommend that you start with a DVD though. The thing with Pilates is that you need to be engaging the right muscles for it to be effective, and in the beginning it can be really hard to do this. The stronger muscles tend to take over unless you are in exactly the right position, with the right things relaxed. I think it is really helpful to start in a small class so that the instructor can correct your position and help you to learn which muscles to turn on and off. Once you have done that and are familiar with the main exercises, then you can use a DVD at home.
