This video teaches your muscles to work the way a dancer's muscles should, so when you go to class, you will be able to receive the full effect of teaching instruction. I live 45 minutes away from the ballet studio, so I like this video because I can practice as often as I should to keep my body ready to dance.
There are two minor things that I need to get used to with this video: a) the sound is not very good, so I have to turn it up loud to hear the music to keep in time, andb) plies, tendus, and degages move quickly; I usually like a slower plie, a slow tendu, then a fast tendu and fast degage. I suppose the video is not as long as to incorporate all elements of the 90 minute ballet class I am used to.
