Allow me to chime in and be honest
I have to honestly say that if you have my newer workouts that you will not be nearly as cardiovascularly challenged as you are with the current tapes. This tapes ranks as a solid intermediate level tape. I myself, and we as a company have improved very much since the production of this video. At face value, I find the actual workout to be a thorough intermediate level step aerobic workout. However, if you are the type who is very particular about music, the background exercisers' enthusiasm, and perfect production quality, this tape is not a good choice for you. If you are not sure about keeping this tape, it is the holiday season(a perfect gift giving time)and this tape would qualify for getting a friend who is a little intimidated about starting up with a fitness program an enjoyable start IMHO. I hope that you didn't mind my honest input. I apologize if I have caused a dilema.
