It's worth noting that the anatomic accuracy of classical statues like Laocoon, the Farnese Hercules, etc. indicates that there were at least some men walking around in antiquity with an amount of muscle mass that could only be developed by deliberate hypertrophy training of the whole body, as opposed to just getting muscle as a side effect of specific athletic training. It seems like these people were doing something quite similar to modern bodybuilding, goal-wise.
