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.
How much weight you can lose in a month by drinking water and doing crunches every night also depends upon other factors. These include you start weight, gender, age, diet, metabolism and how many crunches you do each night.
seven crunches.
You do crunches every night! leg lifts too! start at as many you can do in a row with out stopping for a break then the next night add one to that. then the next night add one! so on! in for some reason you don't do one night make up for it the next day!
Crunches will help you to get abs however, you will not be able to see them without losing weight. If you have a layer of fat over your abs, no amount of crunches will give you the abs that you are looking for.
Losing weight can be hard. If a person eats less, and exercises by doing crunches and running, they will lose some weight. The amount is dependent on how many calories they put in their body, and how many calories they burn.
a good amount but if he/she did not eat all of it last night you could leave it but it matters how many hermit crabs you have but do a good amount!
20 calories per 100 crunches, if you're doing them correctly.

For my school athletics, I do the following crunches: 30 crunches, right elbow to left knee 30 crunches, left elbow to right knee 30 crunches, legs bent to the left 30 crunches, legs bent to the right. That adds up to 120 crunches. You could do many more, or even less. It really depends on how fit you are.
