There is no such thing as spot reduction. You cannot reduce fat only in your abdomen by doing crunches. Unfortunately, that is not how it works. You must lose total body fat to have less fat in your stomach, so burn more calories than you're taking in. Crunches help burn some calories, and help define your stomach muscles, but will not burn fat just in that area.
Simple cardio and excersices can result in you loosing your goal weight. Doing crunches on your couch and doing leg raises can result in weight loss but it will give you the biggest ab burn ever!
20 calories per 100 crunches, if you're doing them correctly.
Do lots of sit-ups and crunches Okay no. All that will do is build up your layer of muscle. Your stomach goes... Muscle, fat, and then skin so by doing crunches and sit ups all it does is make your abs bigger. Not burn fat. By doing this u will ultimatly end up looking bigger than before.
doing about 20 crunches a day at the same time each day will help burn your stomach fat your body fluctuates in 24 hours so when you do exercises the same time each day your body will fluctuate out the same amount of calories,getting better and faster results. try doing them at night right before you go to bed.
Doing crunches won't make you bloated, it will help burn belly fat and gain abs. Eating junk food will make you bloated and fat.
Doing crunches does not make you skinny. Eating less calories than you burn and being active (cardio exercise) will make you skinny.
To burn stomache fat and get a flat belly, do not try to find the easy way out, through medicine, drugs, machines, etc. To answer your question, you need to do crunches/sit up each day until a point that a bit beyond the point that you start to feel a "burning" and soreness sensation in your stomach or abdominal area. Doing crunches will work out your abs. Leg lifts, and other abdominal workouts will also help.
Yes they are but you should warm up really well before and start doing crunches right after the other exercise; it will burn more!.
I have no idea what the previous person was talking about.Anyway, 100 crunches burns about 50 calories.
No. Sit ups and crunches do nothing to lower stomach fat. You can not "target" fat loss. You have to lower your total body-fat percentage. How you do that is to lower the amount of fat you consume in your food and up the amount of exercise you do to burn the fat that is already there. Also, Sit ups and crunches are very bad for your back. If you want to develop your stomach muscles, you should do various plank exercises. If you Google "sit ups are bad for your back" you'll see literally hundreds of pages of documentation that shows why they are bad for you. Personal fitness instructors who know what they are doing do not have their clients do sit ups and crunches anymore.
Studies have shown that localized exercise does not burn fat in those areas. Sit-ups will not burn stomach fat and face-crunches will not burn face fat. These exercises only tone and build muscle. To lose fat you need to burn more calories than you consume by doing cardiovascular exercise.
