HRM and Calculating Calories Burned
I have an old basic Polar HRM that does nothing but calculate my average heart rate and the total time exercised. So, I know how long I am running and I have the the average HR for that period of time, but now I need to know how to figure out the calories I am burning during that time. Can anyone point me in the direction of a good on-line calculator which I could use to get the info. I will eventually get a fancy HRM that does if for me, but in the mean time I need some guidance.
Thanks!
