Okay, so I definetley have a flat stomach, and I'm pretty toned so its weird that whenever I sit if I stand up I get red lines across my stomach. They're not stretch marks or anything because they disappear after awhile but they're still really weird. Anything I can do to stop this?

Haha, I get the same thing. It's pretty much just a crease from sitting. Even if you have a flat or toned stomach, there's SOME meat on it, it's impossible not to have some. The only thing you can do to stop it is to sit up straight and not slouch over.1
