In order to build better abs, don't work your abdominal muscles too often. Your ab muscles are just like the other muscles in your body and require rest. Don't work your abdominal muscles two days in a row, only work them two or three days a week, with at least one day of rest in-between.
Great looking abs will get you attention wherever you go. To get great abs, perform this simple exercise for five minutes, every morning. Lie flat on your back on the floor or on a yoga mat. Slowly bicycle your legs up and down in the air, as if you were pedaling a bike up a hill. As you push your legs away, make sure to fully extend your legs so that your knees are straight.
Do not equate a workout with calories burned. A lot of people make the mistake of deciding that just because they had a workout, that means they can add on a few extra servings or eat that fattening desert. Weight loss in fitness is about burning more calories than you take in. If you eat to replace the calories then your net gain will be zero.
