Many of us has seen guys with no legs, but for my case those big guys with large upperbodies but pathetic wheels are just relative big at about 190-200 lbs max. Maybe around 17'' arms and 23" wheels. However my question is, is it even possible for a really HUGE guy like lets say 240 lbs 10% BF with 50+" chest, 20" arms to have really small legs?

Cause in order to be that big, they must surely eat like mad, so even if they hardly train their legs, isn't is natural for their wheels to grow naturally to a decent size as well?
