I get what you are meaning to say, that secondary sexual characteristics dictate certain trends and limits. I agree.

However, what I find interesting is that historically, the bulk of manual labor was done by the lowest class cultures. It depends on the time and place, but indentured servants, slaves, and women of the household were expected to do most of the labor. These decisions were not made on the merits of absolute physical strength, but rather by ones social status.

In fact, the strongest men. Those with the most physical apitude and power, tended to enjoy leisure at the expense of these lower classes. Including thier women.

The idea that strong men make strong countries, or do the best work, is a myth. Typically, wealth is built by poor men, women, and subjugated social classes, and the mythical status of the strong man gender stereotype serves to justify this arrangement.

So yes, the strongest biological male human will probably always outlift the strongest biological female, but the actual outcomes of who does the work is decided by gender, and historically, the labor fell on the woman. See what I mean about gender being, "bad?"
