I would say run/cycle to lose weight, either on treadmill/fitness bike or outside. About 1hr per day for that. 300-500 situp/crunches combination (takes about 30 minutes) in order to build abdominal muscles, and the dumbbells to build arms (whatever rep until your arms feel tired, but not extremely tight). You can lie down and lift the weights from your arms in a T position up to build chest muscles but benching is more effective.

My dad had me and my brothers do some whacked out ab workout program when i was 12, it entailed doing 1000 crunches every other day.  Of course not 1000 straight, but more in sets, like 200 of legs lifted crunches, 200 legs spread apart crunches, 100 booty lifts with your legs 90 degrees from the ground, 200 bicycle kicks, 100 flutter kicks, 100 kick offs, aaand 100 leg lift offs.....we did that for about 2 to 3 weeks, and around the 3rd week i had freakin abs of steel.  Takes a long ass time though, normally the workouts entailed up to 3 hrs, and your stomach will feel like someone literally ripped you open.  Of course now i've read that apparently doing TOO many crunches can weaken your stomach muscles, which can cause injuries to occur easier such as hernias and what not.....but if you eat right, strecth before and after these exercises, and take your time and focuson the muscles, and not the quick get it out the way kind, you'll have abs of steel again in no time.   Just gotta stick to the program for at least a month.

Whatever exercise you do will burn calories and, with proper diet, result in weight loss.  However, the weight is lost all over, not just in the area being exercised.  Doing crunches will help you build abdominal muscles, which will look good once the weight is off, but it will not cause you to lose weight only in your abdomen.  Cardio exercises are best for weight loss: Using a rowing machine or "skiing"-type arm movements (like you get with an elliptical trainer) are good ways to burn calories without using your legs.  Swimming with a styrofoam buoy between your legs is also great exercise.

first you need to find out if you are performing these exercises properly.  if you are, then maybe it takes longer for you to feel the burning sensation.  when i do crunches i don't start to feel anything until i'm around number 30.  that's because my body is getting used to this exercise so i must increase the reps.

The best way is to do crunches. Start out with like 20-40 a day. Slowly work your way up to about a 100-120 a day. It will work. That's what I did. works wonders.

6 minute crunches..do a minute each of different types of crunches and end it with 6 inches..which is where you lay flat on the ground.with your back to the floor and then you raise your feet up 6 inches and hold it for more than 30 secs until you feel a burn and keep forcin it until you cant take it anymore..do it 4 to 6 times a week and maybe you'll see some results..

Cardio is going to burn off the body fat you have covering your abs. Crunches are going to tone the abs underneath the body fat so that once the body fat is gone you will have shapely muscles. And if you've been eating cheetos, that's not really going to help.... :)

You have two options. You can cut calories and perform crunches like crazy, try one of the hot new incredible infomercial ab devices and buy a “fat burner”, Also there is another  option but it is not too popular. Eat right, Understand functions of the abdominal muscles, work the body as a whole, and allow for ongoing fat release. Of all of two options, there is only one that "works," all of the time. Unfortunately, it “appears” to be the most complicated. \n\nHere is the Real Ab-Solution:\n\nBefore we go any further, I would like to point out that slimming down your abdominal parts REALLY means reducing you body fat percentage in those areas. Therefore, the goal is to reduce your body fat percentage.  \n\nNow that we understand what we are seeking, let us zero in on the solution.\n\nStep 1: Eat right\n"Eat right" sounds so simplistic, but the idea is maximize natural unprocessed foods and minimize processed or junk foods (Please do not go on a depravation diet, it will make things worse). However, you also need to eat in a way that supports Fat loss.\n\nThe real trick lies in stabilizing blood sugar, which allows fat to be released from your fat cells. You would do that by eating meals free from simple sugars and refined carbs, low in processed saturated fat, and balanced with protein, complex carbs, fiber, and essential fatty acids. \n\nStep 2: Move\nOnce the fat is release from the cells, they need to be burned in your muscle cells. Releasing the body fat is not enough; you need to support your nutrition with a more active lifestyle. If you are not active, the released fat just goes back to the fat cells and they are not burned. Burning that fat make your “six packs” visible. You not only need to work on your abs or core muscles but you also need to work you the body as a whole (focus on the major muscles like your legs and back).\n\nThen you need to optimize circulation with moderate aerobic exercise (do not go crazy), and fat release should be consistent and ongoing, and a little at a time, those abs will shine through.\n\nhttp://www.charlesblain.com\nhttp://www.fitmindtraining.com

If you do more than 3 sets of 20 for crunches you are wasting your time.  "Lower abs" actually don't really exist, there is a long muscle from the bottom of your chest to your pelvis called the rectus abdominus, which is all one muscle.  It can be activated in sequence with "crunching" exercises generally activating more of the top of the muscle.\n\nFor the lower part of the muscle you do reverse crunches.  You lie on your back with you knees bent at 90 degrees.  Pick your legs up off the ground and raise your legs up.  At the end of the movement, make sure to lift the hips off the floor to really get the abdominal muscle.\n\nIt has also been shown than crunches on the stability/physio/exercise ball activates all the muscles in the abdominal region (due to the extra stability needed to stay on the ball), including the upper and lower parts of the rectus abdominus.  Picture at:\nhttp://www.popularfitness.com/exercise/exercise-balls.html\n\nThe reverse crunch can be performed on the ball, this website has a picture:\nhttp://www.ediets.com/news/article.cfm/cmi_1211578/code_12738 (I don't like the rest of this website, so just look at the picture).\nYou can do the reverse crunches on the decline bench as well.\n\nHope this helps

Well since you have many ab muscles you can't kust do 1 ab exerise. I would say at least 3 per group. A really good women for women is the reverse crunch. Lie on back , put your legs up so you form a 90 degree angle, lift your shoulders slighty, try not to let the lower portion of your legs fall out of the 90 degree angle. \nbeginner 2 sets of 6\nintermediate 3 sets of 10\nadvanced 4 x 12

First and foremost, stay away from any ab machine as they are simply a waste of money and barely effective.\n\nI just love when people talk about doing 100s of crunches.  Waste of time and waste of energy.  The abdominal muscles work just like any other muscle and have to be challenged as such.  First of all, high-repetition crunches will work nothing more than your endurance.  If you want muscular abdominals, you have to challenge them with resistance and good form just like you would your chest, your back or any other muscle for that matter.  Targeting the correct energy system is imperative.  This means you should never enter into the aerobic phase of this exercise, ideally keeping it under 2 minutes at most.  \n\nThink of rolling a carpet and contracting fully on the top of the movement and squeeze.  If you do them correctly, you shouldn't be able to do more than 30 crunches.  Any more than that, and you're probably doing them half-azz, incorrectly or with a partial range of motion.\n\nFor the upper abs, focus on crunches which effectively work the abdominals better than sit-ups or any machine on the market.\n\nFor the lower abs, keep in mind there is very little muscle tissue there so decreasing levels of body fat is the most effective way to bring out the best in this area. Hanging leg raises, v-situps and reverse curls are among some of the best exercise for this region. Always make sure your pelvis curls up to maximize lower abdominal contraction during these exercises.\n\nAs far as fat loss and getting ripped goes, cardio, cardio, cardio. In the morning, on an empty stomach at about 70-80% of your maximum heart rate for about 30-45 minutes. This combined with a common sense diet will quickly shed body fat so you can actually see those abs you've developed. \n\nI would encourage you to seek the advice and guidance of a personal trainer in your area for further education on these principles. Please ensure you start off at a very basic level for crunches and cardio if you are a beginner.\n\nHere's a good list of ab exercises:\nhttp://www.preventdisease.com/fitness/Strength_Exercises_abdominals.html

The best workout for the abs is crunches. Dance or move for about five minutes then do about 25 crunches a day twice. And another one is lie on a mat and pull your legs together high up do it about 10 to 20 times. Also Dancing is good, for specific like belly dancing thats why they are in shape, like Shakira she's got good abs because she is the best belly dancer. And Cardio exercises like walking or running on the treadmill and increase speed and incline as time goes by. And thats the best ways to look great. Good luck. And in no time you will see a big change.

In addition to crunches, if you have fat in your midsection, you'll also need to burn some additional calories if you want your toned abs to show.  Good workouts for this are walking or running or anything aerobic.  Also do ab exercises like crunches, leg lifts, bicycles, reverse curls, etc to work those ab muscles.
