HRM vs MFP vs treadmill!

Options
Good morning!
I have been excited to start using my heart rate monitor (New Balance N4). Yesterday at the gym I ran 20 minutes and according to the HRM it said I burned about 157 calories (granted, I was taking it easy). The treadmill was picking up my heart rate monitor reading, but it said I burned 220 calories, and MFP gave me 210 calories. That is a huge range!! Should I go with the lowest (kinda a bummer), take an average of the three. OR try it again today and see what happens? I will mention that I used it for a spinning class and the calorie burn on the HRM was much closer to MFP. Thanks!!

    I would go with the hear rate monitor... usually I find that MFP has higher numbers than the machine I'm using or a hear rate monitor.

    i go with my HRM. My treadmill and mfp are 100 calories or more OVER. I'd rather take the lower and work out more i guess... my hrm also tracks mileage as less. when i used to just follow the treadmill i thought i was doing nearly 6 miles a day and if my hrm is correct its almost half! craziness!

    I had that same issue but between my HRM, MFP, and a pedometer program for my iphone. after some research, and talking to my doctor, I found that the HRM is a more accurate reading of you calories burned, as it take into account your heart rate, and what exercise zone your in. (ie: fatburning, aerobic, or cardio) but with the treadmill reading off your HRM, I'd take an average of what your HRM, and the treadmill read.

    You need to go with the hrm number but also reduce the calories that you would have normally burned which is roughly 1.5 calories per minute. I worked out this morning for 60 minutes and burned 400 calories. 60 times 1.5 is 90 so I only counted 310 calories burned.
