I’m wondering if you could take all the “fun” manual jobs like smashing things with hammers, and contract them out to normally-desk-bound people, who do it for minimum wage (for the task at hand). So then you have a large work force who individually only do the manual work for a small part of their time each (e.g. one day a week/month), maintaining their usual career the rest of the time.
What other kinds of manual labour do people enjoy? It’s pretty much just smashing things up for me I think.
