I don't know what to do, i've only been able to gain weight over the past 11+ years, it's very frustrating. But i went running on Friday, starting over with Cto5k Week 1, and rode my bike about 3 miles yesterday, which wasn't especially strenuous (younger siblings came along, so there was a lot of stopping and starting), but i am sore from the running, which didn't go as well as i would have liked.
Trying to lose weight is incredibly frustrating. Training and dieting are both futile, and any time i'm not training...well i pretty much weigh more than i ever have before right now. In fact, it's getting pretty dire. I just wish that i knew what to do about it.
