IMO Harrison Ford looks pretty damn fit in that picture and I wouldn’t bat an eye if he were in a super hero movie today. Like that’s not a Thor body but there are many characters where that body would fit in just fine. I agree that movie bodies are not very attainable for most people with busy lives, but on the other hand, if you’re playing a super hero you’re not playing an average person. It would probably be weird to see an average body shape doing the impossible stunts you see in action movies.
