Not being a bitch at all - just find it bizarre that in your original post, you said "Stomach exercises won't give you a flat stomach", "All you need to do is have a healthy diet, low in saturated fat", "do some Cardiovascular exercise at least 20 minutes 3 times per week" and "What also helps is pulling your belly button in towards your spine".
Now, all lovely jubbly, indeed, but by indicating that this is how you get a decent stomach is odd.
Are you telling me that all those fancy machines and all the gyms, etc around the world are wrong?
I'll just say that i would rather follow the instructions of a professional.....
