Query: What A Joke!

I purchased this dvd after the birth of my daughter and with high review from a well known magazine. To my suprize, I found that herculese himself would have trouble performing all the moves in this video. I could barely make it halfway through a 40 min session that expects you to do over 100 different types of crunches and "ab challenges"! There was also no cardio on the video like it implies. Not realistic at all. I was very disappointed and recommending this to a new mom would be an insult!
