Is this possible? I'm confused... Again.
I just got done a 2hr workout. I did Bob Harpers inside out method DVD and got on my treadmill. I got a heart rate monitor yesterday so that I could try to get a more accurate read on what I'm burning. I was definitely pushing hard and sweating... Out of breath, whatever. According to MFP and my treadmill I burned over 1000 calories. According to my heart rate monitor I only burned 616. Is this possible that there would be such a drastic difference? I believe I'm using it right, calibrated it with my age, weight and height. Everything I'm seeing is that the HRM sometimes shows more calories burned than MFP. Fanks in advance.
