Curious About Insanity...

Options
I'm currently on my last week of TurboFire and I will be starting Insanity soon. I'm curious if anybody has done it and what the typical results are. I know you have to put a lot into it to get good results, so I'm not planning on just going through the motions. If anybody had pictures of their results or wouldn't mind sharing their own personal experiences it would be extremely helpful. I just want to know what I'm getting myself into. It seems like a dream to "get the best body you've ever had" in 2 months.
