Running from Problems

Alright, listen up, you big lug. The joke here plays on two meanings of 'running'. You, big brain, probably think of 'running' as, like, jogging, right? Good job. But it also means avoiding something, like 'running from your responsibilities' or, in this case, 'running from your problems'. The speaker is making a self-deprecating joke that their 'fitness' was actually just a metaphor for constantly trying to escape their issues, and even that got exhausting. You're probably exhausted just reading that, aren't you? Based fact: You probably also run from your problems.
