necromanceranne 566e9be0c9 Non-workout sources of athletics experience diminishing returns on experience gain (#92206) 
## About The Pull Request

For instances of athletics gains that don't involve workout
machinery/granting the exercised status effect, those sources of
experience suffer from increasing diminishing returns as the person
gains athletics levels.

## Why It's Good For The Game

While I still like that this lets more people engage with athletics
across a round, it did unfortunately trivialize getting higher levels of
athletics by doing some relatively banal activities that took really no
preparation to accomplish. The intended method of getting experience
should be the workout equipment, and so at a certain point these sources
of experience should stop granting free levels.

If someone refuses to interact with the workout mechanics and only
chooses to use these alternative methods, then uh....I guess all the
more power to them but they'll be there for a while.

## Changelog
🆑
balance: Athletics experience gain from non-workout sources, such as
climbing ladders, hopping tables and rope climbing, experience
diminishing returns as you gain athletics levels. To reach legendary
fitness, you really should hit the gym.
