    I have this issue too. Some of the numbers just seem so unrealistic. I actually lower them by 100 to 150 when I log them, just so that I don't go overboard on my calories. I guess I'm going to have to get a HRM too.

    Now see I can enter my weight on the elliptical but that is it. The elliptical does have some kind of sensors that monitor my heart rate. I am 26 yrs old, 5'3 1/2, 227lbs. and today I did 26 mins on the elliptical during lunch at lvl 15 and it said I burned 305 calories. So that is slightly over 11 1/5 calories a minute. I would like to invest in a heart rate monitor too myself as well.

    I wear a HRM with a chest strap. I'm 5'6", 148 pounds, and I burn about 10 calories a minute with moderate to intense exercise. I think the caloric burn on machines is well over what it actually is. Oftentimes, when I hit the 100 calorie mark on the HRM, the machine will say I'm at 180 or 190.

    Don't trust machines - get a HRM!

    So I did a little test the other day for this, and when I increased the resistance quite severely I got up to 14.2 cals / minute according to my HRM. Just for info :happy:

    Hi,

    I know this is an old post but thought I would add an input!

    I am 21, and use the Cross-Trainer 3 times a week for 15 minutes each time. At Level 14, I keep my RPM up at around 95-100 and Heart Rate is usually hovering around 187, so obviously pushing myself.

    At this rate I generally burn around 290-300 calories during the 15 minutes, upping to 20 minutes in the next couple of weeks.

    If you are not a trained athelete, sustaining more then 10cal/min is very hard. So it is really doubtful.

    I'm a 52 year old male, 214lbs, 5'11" and at the gym an hour ago I did 30 minutes on the Elliptical at not less than level 10 during which I covered 6 miles and my HRM reported I burned 403 calories. I had also entered my weight and age into the machine and it reported a burn of 496 calories. The heart rate it was showing at various points during the time was within a beat or 2 of that which my HRM was showing. I'm going with my HRM for the burn.

    No. Id say about 90cal per 10 min. And you burn less fat when your heart rate is too high. Research aerobic vs anaerobic exercise.

    I would knock at least 100 cals off if you're going to log it.

    400 calories in 20 minutes would be a phenomenal exertion level - at 180lbs and keeping my heart rate generally into the 160s on the ellipticals at my gym, my readout is generally around 300 calories for 20 minutes.

    400 in 20 I would say is possible, but approaches superhuman standards, haha.
    And you burn less fat when your heart rate is too high. Research aerobic vs anaerobic exercise.

    You do burn a smaller percentage of fat in the cardio zone versus the "fat burning" zone, but generally the overall increase in calories burned ensures that the fat burned evens out, if not exceeds, that burned in the "fat burning" zone.. and then the other calories have to be replenished somehow too. It's good to hit both ranges though, I think!

    I don't have an HRM, and don't trust the numbers on the machines at the gym, I always take off 200 or 300 calories burned at the end of my workout ( depending onhow long I am on a machine) usually from 20 - 40 min a time , although my heartrate on the machine says its up to 176 at times, I t could be possible, but I doubt it...I really should get a HRM lol

    I don't think it's THAT high, just a little. On the elliptical I do 30 minutes at ~152 bpm then 30 minutes at ~ 135 bpm - this is usually level 17/25 then 12/25. Ellipitcal usually says ~500 calories first 30 min then ~400 second 30. HRM says ~525 first 30 and ~475 second 30.

    I doubt olympic athletes burn 400 cals in 20 minutes.

    That does sound high. I use an elliptical and on the one I use, at moderate sustained effort, I burn about 300 calories in a bit over half an hour. I suppose your numbers are possible ....but seems unlikely.

    sounds high to me, elliptical at my gym are normally about 100cals to high for 30 min. sessions compared to my hrm ... personally I average about 10 cals a min.

    I'd be surprised if it was much over 200 in 20 minutes... even if you're huffing and puffing and sweating...

    No, it does not sound right. Way too high.
