Answer 1

Any decent weightlifting program is structured in a way not to be harmful.

When you’re training, you’re lifting a balanced bar, you focus on good form, you pick the type and amount of exercises you do, you train your body in a more-or-less balanced way so every muscle gets similar amount of training, and you’re doing it for relatively short sessions (say, 3-4 times per week for an hour).

Manual labor, on the other hand, doesn’t have much structure, you’re lifting awkwardly shaped objects, certain muscles work much more than others, people generally aren’t mindful of good lifting form when at work, and they do it every day continually, 8 hours per day.
