A physically active job does not guarantee better physical fitness for many reasons, most of these including:
1. Repetitiveness
Repetitiveness is a harmful factor of physical fitness because not all exercises are healthy. Repeating one can lead to physical harm and/or injuries; science shows that in doing so, people are deceased at earlier ages.
2. Working Conditions
Just because what one is doing is considered fitness, that does not always come with the guarantee of high-quality working conditions. People can suffer in poorly maintained environments, and with physical fitness being a major aspect of what is done in the given environment, conditions are to be largely considered. This especially applies to elderly people who might have a desire to want to get fit; they require adequate treatment in terms of their environment too.
3. Different people, different needs
Not all people who work in physically active demanding jobs require the same exercises. In order to achieve a state of physical fitness, one must have a pure balance of what is needed. There could be one form of exercise being done in the work environment; people who do not need this could be at risk of losing their jobs, their homes, and even their lives. Different people have different standards, meaning that some require what others do not. People who do not or cannot live up to these common standards are risking themselves financially, they could be evicted due to a loss of income, and they could die due to harsh and borderline exhausting work conditions.
