Physical Factors
Musk's build is consistent with mesomorphic genetics coupled with reduced cardiovascular exercise relative to his desk intensive work schedule. His prominent upper torso may also reflect natural fat distribution patterns in middle aged men, particularly those with his body type.
Work Environment Impact
As CEO of Tesla and SpaceX, Musk maintains an exceptionally demanding desk and travel schedule that limits intensive physical training. The seated posture required for extended work periods can accentuate the appearance of a barrel chest while reducing visible abdominal muscle definition.
