First, read the English article below.

Some estimates say that professional soccer players run 6 to 8 miles (9.7 to 12.9 km) during a 90-minute game. That's a lot of running, and you’ll do most of it when you don't have the ball. Learn how to get into open space, how to run to where to your teammate expects or wants you to be, and how to run past a defender who's guarding you.

Acclimating your body to this muscle memory is an important part of being skilled with your non-dominant foot. You want to be able to send corner kicks right to the middle of the penalty area, usually up in the air so that a teammate can head or kick the ball in.
