DAMMN, people. I do 2 hours of cardio and 30 crunchies every few hours. I was just wondering, FUCCK.
Jesus, I thought people were nice. And I probably weigh less than that, because that was way when I was fatter- it's just that I don't have a scale, so I have to go for the worst.

I was only wondering because that way I could see if I should up my diet so I lose in a healthy way.

i use to have a site which would show you how many you burn without doing anything, but its usually between 1200-1500. im 5'3'' 157lbs and i burn around 1500 without working out or anything. let me see if i can find the calculator
