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

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

Answer 1

Nobody spends 8+ hours a day in a gym (well, trainers, they don’t count.) and a huge part of training in a gym and AVOIDING injury is limiting how much you do each motion. Construction means shoving your body however you need to, all day long, to do the job. Proper exercise means a limited amount of time doing specific motions in good form, all of which prevents injury.
