My friends who work in offices (project managers, architects etc.) almost all have back problems. I've been lifting steel around this whole time, and at 35 years old I have no back pain or joint pain beside an ankle I broke hiking at 19 that gets a numb ache from time to time.
Being fit, strong and active is the single biggest protection against entropy. That said, wrecking yourself to please some boomer who pays you shit is a thing too, you need to hold your own and tell them to fuck off when your body tells you no.
