There are two things you need to get a visible 6-pack, whopping great abdominal muscles, and zero-to-none subcutaneous(under the skin) fat. Doing the crunches can give you the muscles in a couple of months, but if you have too much padding under your skin it won't help you. Trouble is, the fat that hides your abs is your insulation and your energy reserve, and we're meant to have some of that. Getting thin to the point of getting great abs basically isn't healthy. It can very likely lower your energy levels and your immune system.
20 calories per 100 crunches, if you're doing them correctly.
I have no idea what the previous person was talking about.Anyway, 100 crunches burns about 50 calories.
bout 50
Depends on what you eat. If you really want to lose weight try jogging or walking. Cardio burns more fat.
Doing crunches does not make you skinny. Eating less calories than you burn and being active (cardio exercise) will make you skinny.
200 crunches burn about 10 calories, so if you divide 10 by 200 you find that one crunch would burn 0.05 callories.You actually burn 50 calories doing 100 crunches, so 200 would burn 100 calories
No it burns more
Ok first of all you must do 100 crunches everyday(if it hurts like the hell take a break just about 1 week). When you did 100 crunches about a week do 100 push ups and 100 crunches. When you did 100 crunches and 100 sit ups a week do 100 push ups if you can a week then do all those thing about a month you see a big difference. Remember not to eat much sweets,chocolate,icecream lots of fat things. Eat meat and fish lots of fruits.
It all depends on your size, weight, and fat % If you are trying to build a six pack, and you already have a low body fat % I would recommend anywhere from 60-100 crunches a night.
you possibly can.
you should get at least $100 or more if not you're getting ripped off.
Just to get a little exercise, maybe 100 or so a day. If you want a really toned stomach and abs, then do maybe 200 crunches a day, along with some other core exercises.
