    For cardio, I did Insanity- the Shaun T workout video- fairly often. (I say did because I'm now beginning to implement FocusT25 instead.) The shorter Insanity videos had about 30 minutes of cardio and I would burn about 270 calories. The longer video had about 50 minutes of cardio and my calorie burn was about 440. Both of these numbers don't please me. I work SO hard when I do those videos, but because I'm shorter and lighter I don't burn as much as others. On the elliptical and treadmill I supposedly burn 12 calories per minute, but if I use my HRM it's only about 8 calories per minute.

    I'm with you Debbie.

    All apps, cardio machines and MFP show a burn 30-100% higher than my Garmin HRM. I'm 44, 5ft1in and 67kg.

    Today for example 65min = 470cals (HRM), average heart rate 138 (100-160 range) (155 is high for me)

    This was my run:
    50min running + 10min walking (warm up / cool down). My run included 4km with an incline of 4.5% in 35min and 7.7km total. 2km were downhill, one of which was walking time cooling down. So that would equal about a 5k with incline in 42min, the rest was flat or downhill.

    Even with a lower, IMO, more accurate burn, I only eat about 50% of these cals back.

    im not sure how someone can train for 60min with there heart rate at 178 I dont know athletes that keep that pace.

    Some folks are effectively (and generally unintentionally) hacking the calorie algorithms in their HRMs with HIIT. Interval training where the "slow" periods are short enough will show incredible calorie burns because the heart hasn't had a chance to slow down too much - but it's a mirage, those numbers are a huge overestimate.

    The HR monitor should be correct.

    The HR monitor should be correct.

    They are only correct under some pretty specific conditions, none of which are met by interval-type exercise.

    Judging from my heart rate monitor, I burn around 300 calories when I'm on the elliptical for around 45 minutes. That seems pretty low, but I'm not extremely overweight, so maybe that's why? idk.

    The HR monitor is correct.

    This. Cals burned is more than just HR and more than just personal body stats, it also involves VO2. There's a good post about it around here somewhere.

    700+ cal burns per hour are pretty laughable, btw. Anything that's causing greater than 10-12 cals burned per minute other than running is hardly sustainable for 60 minutes.

    I workout 5-6 days a week. My cardio exercises are usually 60-70 minutes long. The cal burn is usually between 750-830 cals each time as well. Depends on how I feel that day. I use a stationary bike with levels of resistance and a cal counter.

    They are quite ok, maybe not the best thing for interval-type exercise as you mention however.

    ETA: This is from the same poster as the blog link above, but it's more recent, not sure how much they differ.

    When I use the elliptical, 25-45 minutes 200-400 calories. When I play tennis or racquetball it is from 45-90 minutes--about 400-850 calories. I find that it is easier to do a lot more cardio if I am doing an active sport. The tennis is more active than doubles--it is a drill where the instructor keeps us moving all the time. I do about 45 minutes on the racquetball,

    As of late, 1 Hour of Cycling is around 650-700 calories.

    I usually do 45-60 minutes on the elliptical and burn between 500 and 625 calories, this includes a 5 minutes cool down.

    usually 400-600 but up to 1,000 when it's nice outside.
