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.
average 40 fit 60 super fit 80 phenom gymnast, dancer, surfer 100.
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.
