Ignoring the depressingly-predictable classist/colonialist tone, it's interesting to note that modern medicine recommends things like pelvic floor exercises to help with childbirth, primarily to prevent unwanted urination during childbirth and incontinence afterwards it seems.
But this observation - if correct - might lead us to conclude that certain types of exercise help the actual act of childbirth more than others.
Do we know if this has been corroborated / debunked? I'm wondering if there are any agencies out there with specific recommendations for those who are trying for a baby, for exercises that are actually proven to make childbirth quicker or less painful?
