Disappointment ...

... at the gym tonight. My trainer decided she'd have me step on the scale tonight to check my progress. 175 lbs! How is it possible that I gained 5lbs? I follow my diet and I work out. I don't understand. My trainer assured me that I had no need to worry, that it was after 7pm when I weighed and I'd just eaten dinner before going to the gym. So I think I'll weigh in tomorrow morning just to be sure.
