Just saw your post and I am familiar with this program and the company that produced the DVD kit, Beachbody. They are the ones behind P90X, Insanity, Body Beast, Turbo Fire and the list goes on. They produce the best DVD's on the market, have an amazing website to find accountability groups on-line and even free fit club groups in most cities. If you follow the routine as described along with the meal plan options they suggest, you will get amazing results. What is also nice about the various programs is that they show you how to adapt each workout to fit your specific level of ability and help you advance and you get stronger. They also provide a money back guarantee so you can try the program for 30 days and if you don't like it, you can return it for a full refund! I am currently using P90X3, the latest program in the fitness line and liking it as well. I am saving a lot of money, its like having my own personal fitness trainer, nutritionist without the major cost.
All that to say, I highly recommend trying it. Remember, if you don't like it you can get your money back.
