So I am at the gym last night (yes, Halloween night). I always like to start with some cardio. I am huffing and puffing on the rowing erg. I see the calorie burn counter click over 300. I thought, good worked off that bag of Doritos. So I wondered for those of you who workout regularly, do you think of the time spent sweating as offsetting the bag of chips or cookies from the afternoon snack or does it instead mean that you're having double dessert tonight? I guess I look at it as penance for my eating sins.
