Perhaps this has been discussed before but I'm not sure how I'd look it up.
How do people know what the muscle structure of an impossibly huge character looks like?
In cases like The Hulk, sometimes Venom, giant ogres in fantasy art, etc. they seem to be rippling and bulging with muscle. Are they all real body muscles that have been exaggerated or do they add fake muscles in to bulk them up?
Look how many intricate little muscles he has! Nobody looks like that, are those real muscles?
Venom is an excellent example. Look how huge he gets! You can't get a human reference for this stuff! lol
