it won't really help you lose weight but it will scult your abdomen.

Some folk reckon doing stuff like this when you have a biut of flab on your stomach just hardens it and makes it harder to shift but I think it's bullshit. you're workign the muscle not the fat. muscle burns fat more muscle = more fat burnt etc...

Do half an hour to an hour of cardio and then this everyday and you'll see results within a week fi you eat properly.
