I know this is advertising, and I will probably get a couple hours' ban for this, but you guys have got to try the P90X workout! See my avatar? No Photoshop at all. This is after a week of P90X. Epic!
EDIT: Give it a sec, my gravatar has to update. Just click my name until it updates completely.
My personnal workout starts by getting out of my bed, then I like to do ~ 1 Hour of Programming, 10 minutes pause, I repeat until 9:00 PM then I go to sleep. Do that for all summer and you'll have a Six Pack in your brains.
