Uhh yes it is? Lol, idk why so many people are trying to say this guy is incorrect when it's simply a fact that some people have denser muscles than others.
Its minimal and completely irrelevant to the video. All the video shows is the worker has better technique, and his only muscular adaption will be muscles required to move 4 bags of cement (back and forearms).
I mean that's fair enough, but some people do genetically develop more muscle density than others and that could also be a factor here. I dont think its the singular cause for him being better at it, and hardly the most contributing factor but to wave it off as though it's not a thing is dumb to me. A lot of thin guys are much stronger than they look specifically due to muscle density, you get that in football (soccer) players all the time.
