Insanity and burning cals

CapnBO

So this is like my third time trying to do Insanity. I've only ever gotten to week three so i'm really pushing myself to finish this time. With this site and actually having the calendar on my wall I believe i can make it. I just finished my second day of my second week today. What I really want to know is without a HMI what is a good way to count the calories? Like what good key words can I use to roughly count the burned calories?
