Well, I always try food when I travel. I don’t think any food is unusual, as if it’s eaten there it’s obviously usual there.
These are humans in their “natural state”.
I assure you, these men are in superb physical condition. Chances are they’re fitter than you. However, they’re not excessively muscular, at least superficially - nor is any “natural” animal.
There are no Arnold Schwarzeneggers hunting kudu in the Kalahari or ice fishing in Greenland. Humans who body-build are doing so to make themselves more attractive to potential mates (and yes, that is really why you’re doing it, regardless of your sexual orientation), not to aid their survival.
Humans depend on tools for hunting, and so we have little use for immensely strong muscles (throwing and running are the main things we’re “supposed to” use our muscles for). Most large predators require musculature, and believe me, they are muscular.
