You can....
Let your villager excercise
Letting them exercise will gain building skill? ...
Yes, in VV2 as in VV3, when a villager makes exercises he may get some building skills. At the end of the exercise, he stops and sit down to have a rest. Then he gains skills or say "no", they don't!
So, you may make a stew or a potion that makes them "exercise"!
