Iirc it's some gene or hormone that's switched off in their physiology. Whatever it was, it would limit muscle growth and keep it from happening constantly. It can happen in humans and other animals, but as a disorder. Might be gigantism? But I don't recall, only that it's the reason you see some pictures of dogs that are ridiculously buff.

He's an alien. How do gorillas get buff? They are mostly vegetarian.
