Online Calculator for calories burned based on your Avg HR
Today is Day 13 of Insanity
I liked this website where you can put in your age, weight, duration of exercise, and average heart rate. I did 54 mintues of Pure Cardio and then Abs and got an average heart rate of 167 beats per min (90% of my estimated maximum heart rate (186bpm). My heart rate max was 186 with my Polar F1 HRM. My calculation came out to an estimated 714 calories burned per hour. In 54 minutes and 6 seconds I will burn approximately 644 calories! WOW.. I am drenched in sweat!!
