Deliver baby without preparation/exercise

Hi any mummies did not do any prenatal exercise, yoga, bouncing on ball, eat dates etc to prepare for labour but still managed to deliver baby naturally ? Im abit stressed whenever i read that we need to eat 6 days a day, do squats, penatal exercises to prepare for labour but i dont think i would want to do it. But also scared if i dont do it i wont get to deliver my baby. Anyone did not do any of these but managed to still deliver their baby healthy? #FTM
