Say you’re trying to get in better shape.
Start with a little.
Start with a .5 mile walk for a week.
Then maybe make it a .75 mile walk the next week.
Then maybe make it a 1 mile walk the next week.
Then the next week jog .5 miles, walk .5 miles.
And so forth. And in a pretty short amount of time, you’ll be jogging a mile.
