@GoblinGuy it's called Myostatin-Related Muscle Hypertrophy and is a genetic disorder of varying severity that, unsurprisingly, numerous strongmen and strongwomen have. Oddly enough because it is a genetic disorder it isn't unfeasible for their to be a "race" of people with it if they selectively breed to maintain it.
As a side note it also occurs in certain animals (like cows) and is prevalent in certain domestic dog breeds; ever wonder why some dogs are jacked AF? That's why lol.

Really? I would think just needing a wheelchair would be a blessing, unless that isnt his biological kid. I would think that dude is definatly strapped down to something to carry him with since he likely has a powdered pelvis though. If this 6 year old kid's arms are anything to go by, the Mother should be able to lift a car at least.
It would be an interesting twist though if dad was the only biological parent who had amazon ancestors somehow. And his current wife (kids step mom) was super skinny.
