My comment to this question is last Friday I did 40 minutes on the cybex elliptical machine level 8 of 10 hills program. Said I burned over 500 calories. Sounds good?
That night before the pinside meet and greet hosted by JJ I ate the nachos at Twin Peaks the menu said it was 2400 calories plus I had 2 large beers. I rest my case.
Cheers
