What does the line under someone's name mean?

The line under someone's name says what they are doing in Kovo. "Locked in on a workout" means they are training right now.

It is a different thing from the green dot next to their picture. The dot answers whether they are here. The line answers what they are up to.

The line only describes what someone is doing inside Kovo. It says nothing about where they are or what they are doing away from the app.
