After trying a lot of different Pilates workouts I have to say that Stott is where it's at. The Ana Caban's were my first ones and then the Breakthrough video and some Crunch ones and they were all just BLAH. Some reviews of Stott said that Moira Stott was very dry and clinical. I argue that if you were to compare how she teaches with Caban that you can spot right away how clinical can be a good thing. The flow of the workout plus how she balances it with working your back and abs and breathing makes absolute sense. The speed of the level 4 workouts are good too. I bought a Winsor Pilates one and although it was decent, it wasn't as rounded. Working out to Stott also gives you quick noticeable core strength that is much appreciated now that I'm trying to run.
