I have actually taken this yoga instructors classes in NYC and found them to be some of the best at Crunch at that time..Also, as beautiful as MsMcGee is,she is very modest and sincere..The thing about this tape is that as one OTHER reviewer stated it is for the HIP crowd..There is HOUSE music, and a dj,and slick camera shots..as well as a bunch of "hotties" doing the postures..I am a bit old for this "slickness",however the work out is decent,and I did feel invigorated afterwards..I would reccommend this tape to those 18-27 years old,OR as an addition to other tapes to break the monotony..Not bad just HIP..
