Maintenance of one's muscular-skeletal system is a Goldilocks problem. Too little exercise leads to atrophy, but too much also leads to degeneration. Eg the productive lifetime of slaves in the labor-intensive Caribbean sugar plantation system was only about 10 years. Breakdown of joints, ligaments and tendons was a common problem related to overwork (and is commonly seen in athletic training today).
Similarly, my understanding of the history of yoga in India is that it was introduced because of the sedentary lifestyle of the Brahmin caste, and much like with office workers today in the USA, it served to keep them in decent physical shape.
