Yesterday I rode my bike over 30 miles. I haven't done that since last summer. It was hot and I was sweating pretty bad most of the time. by the time I got back, I was a little dizzy. I probably should've taken it easier since I haven't done it for so long. Anyway.. I was expecting to see some weight loss today, but I was 4 pounds heavier. How does that happen? I didn't eat more than normal or anything. I know that significant weight loss doesn't happen overnight and that if I did lose weight, it would be mostly water weight. But to put on four pounds seems kinda strange.
