Do sit-ups really flatten your belly?

I agree with Wiggles and LaDeBoheme, sit ups will not born fat so it will not gonna cause a flat belly. As you said it is a Myth. For flat belly you need to have low body fat %. 5% for a male, and 11% for a female.. To burn fat you need to do mostly aerobic exercise, long exercise on medium power, like jogging swimming or long walking. Sit ups is ain't a good drill any more, cause it heart your back, the best is to do it with straight legs and to lift your body only until your scapula are leaving the floor, hold for 5 seconds and relax. Enjoy :)

Why wouldn't sit-ups flatten your belly? They work out the muscles in your ab region, thus building muscles and eliminating flab! :)

well i think they do and if they don't at least you are using up the calories so its a win win.

Sit-ups/crunches strengthen the ab muscles, but don't remove the fat layer on top of them. You have to incorporate proper diet and aerobic exercise to help burn the fat off.

True, it is impossible to burn fat in only one targeted part of your body at one time. Your body burns fat all over your body at once- so, the best way to burn fat from your belly, would be to do a bunch of cardiovascular exercises and what-not- stuff to get your body burning a lot of energy.

I'm not totally sure to be honest with you. But i have always heard that sit-ups actually just tone your belly. I don't think they necessarily "FLATTEN" your belly. But maybe I'm wrong. To be honest, I'm not all that totally sure!

Sit-ups work a small portion of your abdominal muscles the only way to "flatten" your belly is with a calorie restircted diet
