Pregnancy and postpartum are not a fitness problem. They are a medical period during which fitness considerations can be valuable inputs — when filtered through qualified specialists. Volume 30 is the most-deferred volume in the Library, and that is the volume's central professional posture.
Exercise during uncomplicated pregnancy is broadly safe and beneficial. ACOG Committee Opinion No. 804 (2020) is the standard-of-care reference in the United States, complemented by Mottola 2018 (Canadian guideline), Brown 2022 (Australian), and the IOC expert group consensus (Bø 2016 to 2018). The contemporary consensus across these documents: continued or initiated exercise in uncomplicated pregnancy reduces gestational diabetes risk, reduces preeclampsia risk, supports healthier gestational weight gain, improves maternal mental health (Davenport 2018 meta-analysis), shortens labour duration on average, and improves postpartum recovery. The historical "rest during pregnancy" prescription contradicts the modern evidence base for most pregnancies. Absolute contraindications listed in ACOG 2020 require obstetric direction — exercise prescription in those cases belongs to the obstetric team.
