What is the most fun way to get fit?

Definitely sports, so whatever, like football, basketball, yeah, swimming even.

Playing a team sport with your friends.

Maybe like doing something that doesn't feel like actual exercise, so rock climbing or trampleining or roller skating, skateboarding, that type of stuff.

I would say team sport or calisthenics, if that's how you pronounce it, is a fun way to get fit.
