This is an excellent non-impact workout, but knowledge of the basic ballet positions is essential. It features a lot of stretching and toning of your basic muscle groups. It is not like the bouncing aerobic, jump around gym classes that I've done before. It's nice to get back to basics and if you like symphony (Mozart, etc.) it's just relaxing. I've had many years of ballet and it's nice to get back to basics. I have recommended this exercise DVD to a few friends.
