logging lots of burned calories

been at this for a week and trained around 4 days, how accurate are the cybex or any machine for calculating calories, i am 250ibs and 30 minutes on the arc machine was just over 500 calories, still reasonably fit and can push myself, was just wondering how accurate they are

    Not very accurate, but more so then the exercise database in MFP. For a more reliable idea of your calorie burn, I suggest a heart rate monitor. For reference, an hour on an elliptical for me is about 600 calories and that's a very intense workout. Good luck!
