Such a huge difference, and woah for doing 81 mins - legs of steel!

Thanks for the tip, will look out for the HRM that will sync with MFP - too easy!

Thanks, yes the 36 mins does nearly kill me - particularly on days when I'm fasting. The resistance of the random program goes up pretty high, so quads are killing me during the last 5 mins! :wink:

Thanks for all the responses, I will get myself a HRM and use that to calculate calories burnt from now on. Was just wondering if other people were encountering similar discrepancies with calories burnt through exercise.
