breech correction exercises; prenatal exercises to turn a breech baby
Refers to a set of exercises performed during pregnancy to encourage a breech baby to turn into the head-down position before birth. Often associated with traditional Japanese practices.
After doing breech correction exercises every day, the baby turned head-down.
I learned how to do breech correction exercises from my midwife.
逆子 means 'breech baby' or 'breech presentation'; 逆子体操 is the specific exercise regimen to correct it.
体操 is a general term for 'gymnastics' or 'exercises'; 逆子体操 is a specialized medical/prenatal exercise.
Compound of 逆子 (さかご, 'breech baby') and 体操 (たいそう, 'exercise'). The term is straightforward and modern, with no obscure historical derivation.
