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?

Answer 1

Because one is a science based optimal approach for the *most effective* muscle growth while managing fatigue while also (typically) pushing those muscles to failure to at least some extent.

Construction guys are still going to build muscle because they use them, but it’s not going to be anywhere near as efficient as a structured regimented program that a decent level bodybuilder would use.

It’s just apples to oranges really.
