In crunches your legs move up toward your chest at the same time you raise your chest. In situps your legs stay still (feet on the floor). Most peole think that crunches are better for your lower back.

I find plain, old-fashioned crunches are the best thing in town.  Do 100 a day or more, and you'll be set for fantastic abs!

Run Hills and Kentucky 22 Ab work out program\nThe Kentucky 22 is 4 sets of sit ups/crunchs targeting each muscle in your abs..... First set of 22 is a reg crunch/sit up. Next sets you lay on your side and crunch from elbow touching the ground to the opposite knee. Each side gets 4 sets of 22. Next cross your legs and do the same crunch's 4 sets of 22 and finish the same way you started. And don't forget your push ups, always come in Handy!

Do crunches, they work your abs more than sit ups and they aren't as bad on your back.\n\nYou can also try leg raises. You can do them lying down on the floor or if you really want to work the abs, you can do them hanging from a bar (they are often done on chin up bars at gyms) or something else that is elevated.\n\nHowever the best thing you can do for toned abs is to improve your eating habits and reduce your fat intake. You can do all the ab exercises you want and not be toned if you have poor eating habits.\n\nThis site has a list of many more ab exercises and how to do them.\n\nhttp://www.myfit.ca/exercisedatabase/search.asp?muscle=Abdominal&other=Ab

it doesn't really matter, if your doing the same crunches then your only working a few muscles, better to do some to the side and do some leg lifts while on your back, vary it so that all your core muscles are worked,  your muscles will continue burning calories for up to 12 hours afterward, so work as many as you can

Sounds like you are doing the right thing with crunches, etc. ... I think you should also do some aerobics, dance or something like that to round it off.

ab lounge will work, but it requires alot of repitions and you must do it completely the full way. Basically, its a crunch with someone helping you. I would start doing it then move to the crunches

Crunches and Leg Lifts

Neither.  All those do is help build some muscle up.  But if you have fat in that area, all you will have is muscle that you cant see under the fat.  You have to do cardio to burn fat, because spot training does not work- situps or crunches do not burn fat in just your stomach, the fat comes from all over your body- just like cardio.  Do a lot more running and biking 45-60 minutes a day, 5-6 days a week, that fat on your stomach will then disappear.  Do the crunches or stiups to have a nice looking stomach when the cario has removed the fat :)

Focus on crunches which work the abdominals much better than sit-ups.  \n\nHere's a short list, but I would advise to seek the advice of a personal trainer for proper execution and intensity.\n\nhttp://preventdisease.com/fitness/Strength_Exercises_abdominals.html

Press ups and abdominal crunches are effective exercises that you can to at home without equipment and without taking up a lot of your time. They will tone your body and strengthen your core muscles which will reduce your paunch.\nHowever, if you have excess fat as well you will need to exercise for longer or more intensively to lose it, or reduce your calorific intake.

Sit-ups mess with your back and are unnecessary.  Crunches, forward and to both sides, are going to concentrate only on those muscles.  As you get stronger hang from you knees on a bar and do crunches that way.  The more you do the more you can do.  When It's burning it's working.  If you don't have  a lot of fat over those muscles you'll be there in a few weeks, or even less.  Once you reach the burn get to where you like it.  It's sort of an addiction.  At first it's a bad feeling but then you start craving it.  But you need that to get a real solid six pack.

a few good exercises for you:\n1) when you are doing your crunches, twist. bring your right elbow to your left knee.\n2) hold a weight bar over your head (with only enough weight to make you focus on stability, not much) then, standing with feet shoulder width apart, bring the bar to your left side, then back up, then over to the right side. you are only moving your upper body side to side.\n3)the best excercise (hurts like a mofo) is the side plank. just like the normal plank, but turn to your side. lay on the floor and hold all body weight on your forearm and balance yourself on your forearm and foot. hold this for anywhere from 30sec-1min. i promise you will feel it! =)\n\nGood luck to you =)
