student asking question

How I know of "tough" is only from "tough guy" that we say in Korea to people who are strong. But I don't think that's how it means here. What's it mean?

Here, "tough" means "hard" or "difficult!" Ex: It was really tough moving and leaving my friends behind. Ex: Training for the competition has been quite tough these past few weeks.
