Logging exercise calories- machine or MFP?

robinlynn8

I am having trouble deciding whether to log the MFP calories burned from a machine (elliptical, bike, treadmill)... The machine that I'm on says one amount of calories burned, but when I go to log the time and activity in MFP, it shows that I burned a lot more calories. I have just logged the machine numbers to be safe, but which one is really correct!? Help!

Do you train with a heart rate monitor? In that case, the machine is probably more correct...
