This is a great idea!
I am already on my 3rd round of P90X. The first round I lost 14% body fat and 33 pounds (I also put on a considerable amount of muscle)...
They have these programs on craigslist all the time for about 40 dollars which is a big difference from the 120 plus tax plus shipping...
This is a real program with real results...not for the faint hearted or those that think weight loss is a one time routine. (you get where you want to be and then done) Nope, its a lifestlye. I learned this after hurting my back.
Before and after pics (point and shoot style).

:
At 206.4 lbs day 1
At 176.0 lbs day 90
At 171.8 lbs day 120
I hurt my back after the second round and tried to get back into it but my back wasn't feeling it for about four months. I gained a lot of the weight back and now I am on my sixth week of the program (again)...watching my calorie intake isn't as hard as I thought it would be.
The best part of this program is that you FEEL HEALTHY as well as strong.
