Levelling of agility skills

[Walther]

So, to be hones, It's not like i have survived for weeks or so but I've had my share of levelled skills. mostly weapons and cooking/crafting skills but I never managed to level one of the agility skills.

 

what would one have to do to level the agility skills? (Sprinting, Nimble, Lightfooted, Sneaking) and for how long would I need to do that?

 

PLUS: Is there a way to increase levelling for other skills than cooking, crafting and farming?

sneak around a lone zombie, makes sneaking and nimble go up, sprinting a lot is awfully slow to rise sprint level, it takes its time, truely and more drastically than all other skills

interesting, i'll try that out next time i play PZ. thanks
