Other than STS, the April 2013 rotation was the first rotation I have done too. I absolutely loved it! I used to not want the restraint of having to follow a regimen, and wanted to be able to choose my own dvd everyday. However, I have completely ditched that thinking! I have just about all of Cathe's DVDs and the rotations make working out so much more organized and it gives me something to look forward to!!!
I am also ready for May's rotation!
