There are a number of types of physical labor that will cause large 
pectorals to develop e.g. one can find century old photographs of 
laborers working in the fields with shirts off who have a gym monkey's 
physique.  Our bodies have evolved to withstand much more physical 
strain than we actually tend to put on them these days, hence the 
responsiveness of the muscle when one puts it to use.  The state of the 
average human body today is a long way from the evolutionary mean that 
gave us the bodies we have.
