Never heard of this before until I came across with a topic in my class regarding Current Procedure Terminology Codes - CPT for insurance billing purposes. I read about codes in giving birth and there's a suggested to read information about acquiring relief from pain and discomfort due to pregnancy. That there's some exercises that would help to ease the discomfort through effective breathing and relaxation, mind body exercises and many more. I thought you could just go to the gym and any trainer could assist you to do prenatal exercise. I was wrong because it takes a specialist to work on that task. There are specific trainings and certification for competency. It's called Pre-post natal exercise specialist. New found profession, interesting!
