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

Body builders are trying to optimize muscle growth/tone. This means pushing their bodies to the absolute limit (which causes damage) and then allowing time to recover (when the body heals that damage, resulting in growth). It is a plan of extremes designed for optimal results.

Manual laborers are not pushing themselves to extremes every day. The are working _hard_ but they are working within their limits. This means they don’t need the recovery period afterwards to rebuild the damage done by their labor.
