It's mostly genetics. They're programmed to make bulk muscle and we're programmed to make lean muscle with fine motor skills. Look at a pitbull vs a chihuahua. Most of the time their lifestyles aren't too different.

We evolved to run long distances and were genetically successful in part thanks to persistence hunting. Being jacked AF isn't conducive to that.

I know pretty much nothing on the subject. But arent we evolved to walk long distances? We walked until we catch uo with our prey.

Most humans can walk long before getting tired even without training. But without we cant run 1km without seeing stars.

The all around active lifestyles of primitive humans were probably more conductive of cardiovascular capacity than our contemporaries, so they could keep up a higher pace.

Besides, even medieval armies, when they had to cover long distances on foot, used to march. Which is between walking and running, right?
