When I started at the gym they said you cannot tone individual areas. you have to do cardiovascular work to get rid of the bodymass fat and then tone the muscle by doing the dreaded abs work (or wahtever part you want to tone ). They also said that when you start to exercise that you won't lose weight, at least not to start with, as you gain muscle which is heavier than fat, so they advised to take body measurements instead.
So I used to pound on the treadmill for 45 minutes 2 or 3 times a week. I can't run so I power walked. I lost 4 inches off my muffin top and dropped from being nearly a size 14 around that area, to an easy size 10 in about 2 months. And I never once did a situp. It was all from the walking and losing your body fat all over the body. And my weight only dropped by about 4 pounds.
