When you lift weights, you can choose a weight that’s appropriate to you. When it gets too heavy, you stop. When you’re finished, you rest for a day or two. When you feel a twinge, you easy up or take a rest day. When you’re lifting heavy things for a job, you lift whatever needs to be lifted in whatever motion it needs, with incentives to do it quickly. If you’re tired, you lift it anyway. If you feel a twinge, you probably ignore it because it’s probably nothing. Then you do it again the next day regardless of whether you feel like it. Some of that can be mitigated by workplace rules, but it needs pretty radical overstaffing or acceptance of considerably slower work, neither of which Capital is a big fan of.
