I got this mainly for the “rockin’ soundtrack” the back cover refers to, and also because it uses the foam roller for stretching, which sounded interesting. Although the instrumental music is not bad at all, I would hardly call it “rockin’.” It’s unrecognizable and more like what is called “easy listening” music than rock. It’s okay, but not what I was hoping for. The stretch workout with the foam roller is sort of interesting and certainly unique, but not my cup of tea. Many of the moves seem gimmicky and awkward. After one try, I really have no desire to do it again. Aileen is very pleasant and likeable. This was my first experience with her, and I would try something from her again.
