– why is working a manual labor job (construction, manufacturing, etc) destructive to your body but going to the gym every day isn’t?

Question

I’m an electrician and a lot of the older guys at my job have so many knee and back issues but I always see older people who went to the gym every day look and feel great

Because when you do manual labour jobs, you’re using your body in whatever way you can get the job done. Craned over, back bent awkwardly, on your knees for hours… all things that are terrible form and posture. Because the alternative is often that a task becomes impossible.

People who go to the gym regularly and work out often are paying attention to their form and making sure they’re doing things right.
