Giving Blood and Exercising

Alright, I'll just admit it. I go to spin classes. So sue me. Anyways, these classes are pretty damn intense - I routinely lose about 4-5 lbs of sweat during a one hour class, despite the fact that I drink 16-22 oz. of fluid during the class. The web sites I have read about blood donation and exercise all talk about dehydration, and varying time intervals of decreased performance. Any anecdotal experience out there? Nothing would be more emasculating to me than to faint in a girly spin class.

As long as there is about 6-8 hours between the donation and your class, you should be fine. The more conservative approach would be to wait 24 hours. But you'd have to be the kind of pussy who goes to spin class to wait that long.
