    If you are pushing hard and keeping the heart rate up this is very doable. I can burn this amount in 20 minutes on a treadmill. Great job.

    From what I remember of tests done comparing the machine readout to the actual calories burned during the exercise time on the machine in a lab (you know all the sensors and breathing apparatus hooked up while the study subjects were exercising on the machine, ellipticals were one of the worst for over reporting. I would not trust that number especially since it does not have all your vital statistics (age, height, weight, sex) to help get that number closer.

    it most likely is wrong. mfp tells me I burn 1163 calories in an hr on the elliptical (I'm 285 lbs) but according to my hrm its around 420 in an hr. big difference. the machine gives me a number somewhere in the middle but its still off by quite a bit. go with your hrm

    Depending on your age, weight , sex, it varies....someone 225 pounds will burn way more than me in 20 min doing the same workout. Athletes could defenitely burn 400 cal in 20 min, its possible for alot of people.

    An untrained person of 225lbs could not keep up the intensity to burn 400 calories in 20 minutes.

    :sad: My elliptical tells me a bit over 400 in 20 min. My HRM has it a bit under 200. Sorry! :sad:
