There is no set number of calories per sit-up. The number of calories used per sit-up depends on a large multitude of things. How much mass are you trying to move? How quickly are you trying to move it? What kind of resistance are you moving through? What is the exact number of muscle fibers that contract in your particular body when you do a sit-up? Do you use the exact same number of muscle fibers the same exact way for each sit-up? How efficiently do your muscles work? Do you work any muscles on your way back down? The number of calories burned per sit-up is probably never actually known. It would be slightly different for each and every sit-up even in the same person. If there is a figure out there in cyberspace, it is guaranteed to be an estimate, and it is nearly guaranteed to be a useless figure in actuality.
Burning calories is all about getting your heart rate up a bit, and keeping it up. So unless you plan on doing situps for half an hour or more you simply won't burn a significant amount of calories that way.
A person weighing around 150 pounds will burn approximately 271 calories doing 350 sit-ups in 30 minutes. A person weighing 200 pounds will burn roughly 362 calories doing 350 sit-ups in 30 minutes.
That depends on your metabolism. People with a high metabolism will burn quite a few calories, probably around 70-80. With a low metabolism, this number drops though. Hmm, some say it depends how long it takes, and how much effort you use in addition to this. For sedentiary effort, you're looking at around 254 cals in an hour. For greater effort about 560.
To burn 1 lbs., you would have to do about 70,000 crunches.
One sit up does not burn a calorie. It takes about 5 sit-ups to burn 1 calorie.
The number of calories that a person burns while performing 50 sit ups depends on their intensity and weight. The average 150 pound person burns about 30 when doing 50 sit ups.
about 10 calories

Sit-ups have to be done briskly in order to burn a significant amount of calories. Fifty sit-ups on average would only burn about 30 calories.
Doing 30 sit-ups will only burn about 7 calories. The amount of carbs burned is not really something that can be determined as it usually goes by calories.

Isometric exercise will not burn very many calories. While it does burn some, it is a strength training exercise, whereas something like sit ups or running burns calories.
When it comes to burning calories, how hard and for how long is much more important than what you do. Pretty much all activities that gives you the same increase in heart rate for the same time will burn the same amount of calories. Now, it can be a bit difficult to get a good burn going doing sit-ups only, as most people won't have enough upper body endurance to keep doing it fast and long. And it's dependent on weight, gender, age, fitness level etc. But let's say you can do sit-ups at a pace that gets you about as sweaty and winded as if doing aerobics, then you'd need something like 60-75 minutes of continuous sit-ups to burn around 600 calories.
It would be practically impossible to lose weight just with exercise alone. An average person weighing 145 lbs. would need to perform a total of 17,500 sit-ups in order to burn a pound of fat which is equivalent to 3500 calories. This is why doctors recommend combining diet and exercise.
If you were to do situps for a continuous ten minutes vigoursly you would burn 90 calories.
Not very many, but doing all 100 of them in a row will give abs to your abs. I don't know but if you want to burn calories jogging is a better way to do it.

Ok, that stuff was junk. You burn about .2 calories per sit-up for the average person. So in other words, 10 sit-ups burns 2 calories. If you're looking to lose weight, I suggest jogging, walking or running. Again based on the average weight and height 1000 sit-ups is equivalent to jogging, running, or walking from around 2.5 to 3.5 mi. for the average person. Pick your poison. DO one of them for 17.5 days eating around the recommended amount of calories per day, and viola, you have lost a pound, though it also helps to switch out some foods, like eat an apple instead of a candy bar, trade in 2% milk for skim, eat vegetables to your meal, grill rather than fry. All these things will help. directly @topic: .2 calories
The number of sit-ups that you need to do to lose two inches depends on many factors. The first is how much you weigh when you begin. The second is how long it takes to do those sit-ups. The faster you do them, the more calories you burn. Doing 100 sit-ups in 10 minutes will burn approximately 57 calories.
In a 16 ounce bottle of soda, there are about 184 calories. The rate at which the sit-ups are performed will determine the amount of calories burned. If 100 sit-ups in around 10 minutes, 57 calories. It would take around 300 sit-ups in 30 minutes.
