Workout Regimine... Helps

Options
I wanted to know if anyone has done the Insanity workout and what they thought about it? I am the type of individual that has to have someone yelling at me to stay motivated with my workout especially if I have to do it at home. Years ago I had a personal trainer and loved it, but then it got expensive. A group of us at church has started boot camp and loved doing it, but our schedule are so busy so that was out. My husband bought the P90x and never used it. I have Zumba and saw results. But now we have the Insanity (my husband love being training videos). I heard it is real intense, but i wanted to know if it was something good to do. Also has anyone seen results.
