Obviously this won’t work for all sports, but things like football, track, soccer, it would allow for de-gendered team, even allowing athletes with the skills but not the genetically-endowed physical attributes to have a place to play.
Note: I know very little about sports and being on a sports team, so please point out anything that doesn’t make sense.
I feel like weight class doesn’t do it. Women have higher body fat %. Is a welterweight woman athletically equivalent to a welterweight man? I don’t think so.
