How should you work out abs when you are overweight?

You can do crunches.  I would not add weight because you don't want to make your ab muscles bigger, because that will only increase the size of you belly.  You will also not lose weight by doing crunches or sit-ups, diet and exercise is key.

well what you have to realize is that situps only work your upper abs, which get a good workout if you lift weights, the hardest thing to tone is your lower abs.  You should work to fatige (not burn out) your upper abs, then work your obliqus(sides) and then do leg lifts (get leg weights if you're not getting fatigued with just your legs) in order to work your lower abs.  You use this order so your upper abs and obliques don't assist when you work your lower abs.  If you want faster results do a power walk before working abs and run after.  Watch what you eat of course, and increase your potassium(rasins and bananas).  You wouldn't believe how much water weight can cover your abs and the potassium can help reduce this.

You can work out your abs and develop muscle, but if you're trying to get a six pack, you have to burn the fat that covers the muscle so it shows. The ab lounge will build the muscle, but you have to do cardio to burn fat.

Start with 20 crunches lifting your legs at a 90 degree angle for your lower stomach. Lift your legs above the ground and keep them there while you do crunches for the upper portion of your abs. Do side cruches for a slimmer waist. And finally cross one leg over the other and do crunches connecting your left elbow to your right knee. crunch first then connect elbow to knee. Continue to add crunches the more you get use to it. HAVE FUN! :)

In order to have good abs you MUST have a low body fat level, at the least in the single digits.  If you have too much bodyfat, then you can have the biggest abs in the world, but they won't show up because the fat sits on top of the muscle.  So diet and cardio are both crucial if you want to have great abs.\n\nAs far as exercising goes, abs are tricky.  You need to make sure that you are doing the exercises with good form.  90% of all people do ab exercises wrong.  It's way to easy to use the hip flexors instead of the abdominals.  Proper crunches will work the abs, while sit-ups mainly work the hip flexors.  Check the link below for good instructions on different ab exercises.\n\nFinally make sure you are doing exercises for each of the different muscles that make up the whole "abs" ... the upper abs, the lower abs, and the obliques.  Good luckl!!!

Everbody has abs and you can have the strongest abs but if you have fat covering it up, then there is no point. The abs are made up of 3 parts side, upper and lower. my cousin is a trainer and he taught me this exercise and its a killer. You do 25 crunchers and then 25 crunchers to the left and 25 to right. Then you hold dumbbells in your fist to keep your hands down when you are going left to lift your leg up and down. when you are going down, go slowly. When you do these exercise you should contract your muscles. Do 3 sets of this and you are probably sore the next morning but it feels good. if you get to a point where go can do it easily and then go to 50. You have to lower your % of fat which means cardio if you are fat or if your just skinny, then all you need is to built up your abs. For most people it is losing the fat, where you could do half an hour of stair master which like 500 calories times 7 days equal 3500 calories. 1 pound of fat equals to 3500 calories. So if you burn 500 a day and cut back 500 from your diet. Then you would lose 2 lb week which means 8 lbs in a month, if you stick wit it. For diet wise, drink more water and no soda, the carbs are too high. You cant have candy and too much beer. you should have a low carb high protein diet. if you follow what i told you i can 95% than you have abs very soon.

Exercises: Crunches are very effective at toning the abdominal muscles. Do one set of 20 every morning before you get dressed: Lie on the floor with your knees bent. Lock your hands behind your head, and bring your elbows and knees together by flexing your abdominal muscles. Aim your elbows and chest toward the ceiling; lift shoulder blades 2 inches (5 cm) off floor. Avoid fully extending your legs, as this can place too much strain on your lower back.\n\nActivities: Great ab workouts include rowing, tennis and yoga. These activities work the entire set of abdominal muscles, promoting overall strength. (They're also much more fun than sit-ups and crunches.)

Concentrating solely on exercising your abdominal muscles will not do much for your figure.  Keeping your body fat low will bring out the best of your abs.  So far as strength training squats and lunges will do the most for your figure.  Your best bet would be to stick with crunches because they are pretty good, but don't over do it.

Do you mean tummy exercises?  or exercisers?  (there is a difference).  Exercises really do work; any sort of sit up, or try a number of them to work different parts of the abs.  You also need to do aerobic exercise, like fast walking, or running.  That will help eliminate the overall fat percentage of your entire body, including your abs.  Eating right is necessary too.

1) slow down your reps\n2) lower the reps and up the weight\n3) watch your form and be sure you are isolating the   muscles properly with your movements\n3) break up the crunches into MAX sets of 20 or 30, and vary the type of ab work you do (just straight crunches don't target enough)

Cardio gets rid of the excessive fat. If you start doing sit ups or anything to strength your ab muscles without losing the fat first you will look heavier.

lower your overall bodyfat through cardio 3-4 times a week for 30-45min and a clean diet and then strengthen the ab muscles best ab workouts are roman chair situps and leg lifts.  Only train abs twice a week overtraining only breaks the muscles down.

Just do lots of crunches. I do crunches, too. They hurt, but hey, it's worth it in the end!
