Do 10,000,000 crunches in a day, it wont help in the first place. A waste of time. Hanging leg lifts will help tremendously! Olympians do them!
5000 hours is equivalent to 208 days.
There are 365¼ days in a year SO ...365¼ x 5000 = 182650 days
5000 hours is equivalent to 208 1/3 days.
5000 minutes is 3 days, 11 hours and 20 minutes.
24 hours in a day, so 5000 hours is 5000/24 = 208 and 1/3 days
50, spread them out or do them all at once
714 weeks, 2 days
seven crunches.
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.
Since there are 7 days to each week, there are 35,000 days in 5,000 weeks.
It depends on how fit you are!
There is no number for everyone- each person has a different number.
