And up untill the 1940's spiral fractures in various sports were unknown,The base level of exercise from normal activities starting in early childhood built a more robust skeleton and stronger muscle attachment points. Proof would be trivial, as amish and menonite comunities still follow the same practices.....they are not known as slouchers go look at average city kids, and then go look at the ones bieng raised on biodynamic farms, my joke is that the city kids are soft and grey, but the farm kids look good enough to eat, 2 seconds and you see the healthy glow

The sports were massively less competitive back then, incomparable to todays variant. The sports as a super competitive and popular past time is recent development. If less people do sport and sport itself is less competitive, less people will get injured.

Also, while people were strong, they were not buffed. The robust build, six pack and big muscles is our ideal. Men were basically thin.

Fun fact: cities are overall thinner then rural parts.
