If body builders need rest days between training the same muscle group, why are construction workers like scaffolders generally so well built and so strong?

Question

If rest days are required between working the same muscle group how do these guys get so big? A scaffolder can’t rest his lats or deltoids and is working at least five days a week. Sometimes seven. How does this work?
