Hey there, so i need some help with any fitness gurus about the amount of calories i burn with my runs.

I use a Cross Trainer ( Elliptical Trainer ) and i run 9km a day, but i run it in 20 minutes, My Cross-Trainer says i burn 800 Calories for the run, However when i look up calculators and stuff like that they seem to cut it in half.

I Weigh 120kg now, Used to weigh 136kg ( But not sure if the scale i used was telling lies to me when i first weighed in or not, ( Going off the first weigh in a few months ago i'd have lost about 16kg.

I feel like i probably haven't lost that much but i weighed myself today on a digital scale and it came in at 120.5 with all my clothes on and stuff in my pockets ( I re-weighed myself a second time with my wallet and phone out of my pocket and it came back as 120.2).

So what i'm hoping for is someone to re-assure me that i probably am burning about that many calories per 20minute run like the cross trainer says ( Because of my weight maybe? ) Or i am more than likely not burning that much.

20 minute runs, 9km, weigh 120kg - Constant speed of 25-32 ( What i assume is KM Per Hour ) -- I also walk most nights for 3k ( Power walks ) And play soccer every second day for atleast 1-2 hours ( Casual ) But i'm not including that in the 800 calories burnt from the cross trainer, I am super curious to know if this machine is telling lies too.. Thanks in advance! Will check back soon.

    Sorry I'm a bit confused as 9km in 20 mins doesn't seem to add up. Running 9km in 20 minutes would put you in the Olympics. For an actual run it's fairly safe to work on 100 calories per mile.

    Its not real running. Its an elliptical "run".


    If you want to OP, get a heart rate monitor with a chest strap.

    A heart rate monitor will give a better indication of how many calories you are burning. As someone who has been running for about 3 years and weighs 190 pounds, it takes me about an hour of running to burn 900 calories. Even when I weighed 230, I wasn't burning more than about 1000 calories in an hour. Your 900 calories for a 20 minute workout is probably closer to 300.
