I have a computer job, so I spend more than nine-hours per day in front of the computer (yeah, I know, hoooorrible!). Because I sit a lot, and I don't like sitting up straight, it affected my stomach. What's the fastest way to a flat stomach? What food should I avoid? and what exercises should I do and when should I do them? I take a 20-minute-jog every morning but that's definately not enough. I do it about 10 minutes after I eat breakfast which is I know very wrong, but I can't seem to wake up earlier. Is it okay to go jogging three-hours after lunch? Is it a suitable time?
