The endomorph is characterized by a round physique, carrying extra
body fat. The endormorph is has a large bone structure, and has a
good portion of muscle mass. The endormorph has a wide thorax (rib
cage), which makes a large angle with his ribs. It is sometimes
more difficult for an endomorph to keep weight down, but it is
entirely possible that an endormorph make great gains with his or
her training to the point where it may even seem as though his or
her body type has completely changed!
