Why is physically exerting yourself to the point of exhaustion at the gym good for you but various jobs involving manual labor seem to cause permanent damage in the long term?
In: Biology
Exercising on your own for health usually involves a wide range of activities done in balance with one another.
Manual labor is often about performing the same task over and over again in the same way. A guy in a warehouse picking up heavy boxes over and over again. On an assembly line making the same motion with your arm/shoulder thousands of times in a workday. That’s how repetitive motion injuries occur.
