Insanity Cals burned?

briley76

Hi,
I just started Insanity on Monday, and boy it's no joke. I have a Timex Road Trainer HRM with a chest strap. Today, I did Cardio Power and Resistance. The HRM said I burned 1004 cals in about 45 min.

I am 5'10", 220 and 35 years old. My max heart rate was 191 beats/min with an avg of 166 beats/min. through the workout. Does this sound about right. I knew you burned like a mother with Insanity, but I didn't think it would be quite that high.

Can anyone speak to this?

Thanks!
