How does Tyreese STAY so brolic

Tyreese is a big dude. His stature is foreboding. But it begs the question at least to me, how does he keep his strength like that? You have to eat a lot and work out to keep your body built.



As someone already said, this is a universe where food is extremely scarce and running is a requirement several times a day. How does he do it?







love the character btw.
