Try this test
Ok when finished with this test u r going to have a number and that number is going to be the amount of crunches you have to do. Okay ready?
Pick a number 1 to 10. Add 20 to that number. Think of your favorite color and add the number of letters there are to your number ex (green = +5) now add your age. Divide by 2. Add 100. Divide by 5. Add your best friends age and whatever number you have is the number of crunches you have to do.
Tell me if this works I just made it up.
What if u took the division out and instead used multiplication and added a few more fun stuff...like add ur moms age and subtract your oldest sisters age and if u dnt hav a sister use ur brothers and if u dnt hav a sibling add 50 there's like a million ways
