Why should pregnant women serve in the military in the first place?
Oh, I quite agree that pregnant women have no business being in the military. But that's not really the question here. I have no idea about the context of why they're getting instruction on how to conduct classes for pregnant women. For all I know they'll be doing classes on post for soldier's wives or something. And while it's true that pregnant women soldiers have no place there, they -are- there and the instructors that conduct those fitness classes need to know what they are doing.
So back to the original point: that this exercise in the context of training new instructors about the realities of pregancy in fitness training-- isn't as absurd as the headline and first few sentences seems to suggest.
